Re: [Proposal] Drop Wonder's Ant Build

[Dev WO via Webobjects-dev]

I’m like Ted,

I though it would prevent me from keeping my current (ant) projects as they are.
I understand this only applies to building Wonder.
I don’t think it would be fair to ask the contributors to spend time on keeping 
a build system for Wonder that none of them use.

So as far as my opinion counts, I’m not against dropping ant build system from 
the Wonder build:)

Re: [Tomcat] - Resources referenced in CSS not displayed

[Dev WO via Webobjects-dev]

Thanks Pierre,

Just tried it, the files are now also in the “static” tree, but the application 
still generate the url like
http://localhost:8081/CloudManager/WebObjects/CloudManager.woa/wr/wodata=/usr/local/apache-tomcat-9.0.29/webapps/CloudManager/WEB-INF/CloudManager.woa/Contents/WebServerResources/defaultscreen.css

I’m doing http://localhost:8081/CloudManager/static/CloudManager.woa/Contents/WebServerResources/images/logo.png
 
<http://localhost:8081/CloudManager/static/CloudManager.woa/Contents/WebServerResources/images/logo.png>,
 the image is displayed, so that seems to be on the right track, but how to 
make ERXStyleSheet to actually generate this kind of URL...

[Tomcat] - Resources referenced in CSS not displayed

[Dev WO via Webobjects-dev]

Hi list,

I’m struggling with something Tomcat related:
My application’s CSS is working except for referenced items like a background 
image or a font.
What I have so far:
-The images and font are present inside the same folder, everything is 
correctly deployed under Tomcat and all files are there after Tomcat expand the 
war
-No mismatch of case sensitivity for file names either inside the CSS or on the 
filesystem
-Everything is working as expected when running from Eclipse or under 
WOMonitor/wotaskd

Just as a side note, I don’t really have a say on the deployment (Tomcat), all 
static resources must be served through Tomcat and not “split” with a web 
server. Customer skills is zero, Deploy/undeploy under Tomcat Manager is 
already “a lot” for the customer.

The deployment generates urls like:
http://localhost:8081/CloudManager/WebObjects/CloudManager.woa/wr/wodata=/usr/local/apache-tomcat-9.0.29/webapps/CloudManager/WEB-INF/CloudManager.woa/Contents/WebServerResources/defaultscreen.css
for the CSS, which is ok and working
the CSS has relative path like 

@font-face {
  src: url('fonts/ysiweb.woff') format('woff');
…
}
and for the background image
… background-image: url(images/logo.png)…

In the browser’s inspector, I can see the logo.png and .woff font, but even if 
they get a 200 status, they actually have no content (transfer size of 175B for 
both in the web inspector)
The urls are:
http://localhost:8081/CloudManager/WebObjects/CloudManager.woa/wr/wodata=/usr/local/apache-tomcat-9.0.29/webapps/CloudManager/WEB-INF/CloudManager.woa/Contents/WebServerResources/fonts/ysiweb.woff
 

and
http://localhost:8081/CloudManager/WebObjects/CloudManager.woa/wr/wodata=/usr/local/apache-tomcat-9.0.29/webapps/CloudManager/WEB-INF/CloudManager.woa/Contents/WebServerResources/images/logo.png

I've tried adding the mime-types manually to the web.xml, but it’s clearly not 
the issue here.

I found a thread "Tomcat deployment and CSS images” from 2013 by Miguel Torres, 
but he actually changed the context-param WOAppMode to Deployment and “split” 
the resources with the Web Server, something I can’t do here.

I’m lost, I don’t understand what’s the issue here.

Any help greatly appreciated:)

Thanks,

Xavier

Re: [ERRest] - Manually generating rest URL

[Dev WO via Webobjects-dev]

I actually did like ERRest, but directly in my DirectAction

public WOActionResults statusAsJsonAction() {
//assuming dict exists
ERXRestRequestNode restResponseNode = null;
ERXRouteResults results = null;
try {
ERXRestContext context = new ERXRestContext();
restResponseNode = 
ERXRestRequestNode.requestNodeWithObjectAndFilter(dict, 
ERXKeyFilter.filterWithAll(), context);
results = new ERXRouteResults(context(), context, 
ERXRestFormat.json(), restResponseNode);
} catch (Exception e) {
// TODO: handle exception
System.out.println(e);
}
return results;

I should get a better handling for the exceptions though;)

Re: [ERRest] - Manually generating rest URL

[Dev WO via Webobjects-dev]

I cannot really say it is solved based on the subject of the thread, but 
regarding what I was actually trying to do, it is solved.
I picked up just what was needed to generate the Json response in my 
DirectAction class so I could keep what I was using the generate the url.

Thanks anyway, it gave me some time to look at ERRest:)

Re: [ERRest] - Manually generating rest URL

[Dev WO via Webobjects-dev]

I was just looking at making a DirectAction to get a NSDict as a json output 
actually.

Searching for that it looked like ERRest was the answer, but maybe I should 
just “borrow” the method that actually generate the son response and stick with 
the regular DirectAction…

Re: [ERRest] - Manually generating rest URL

[Dev WO via Webobjects-dev]

Hi Jesse,

Thanks for the pointer, that does look better, but I don’t understand 2 things:
The method I have is
actionUrlForEntity(WOContext context, String entityName, Object entityID, 
String action, String format, NSDictionary queryParameters, 
boolean secure, boolean includeSessionID)
I’m doing “ERXRouteUrlUtils.actionUrlForEntity(context(), "Status", null, null, 
null, restDict, false, false)"

I’m expecting a url like 
''/cgi-bin/WebObjects/CloudManager.woa/ra/Status?type=heat”
but I get "/cgi-bin/WebObjects/CloudManager.woa/ra/statuses.html?type=heat”
I don’t really get why I got “statuses.html” instead of “Status” (the capital S 
and the plural+.html).

Looking at the source, it seems whatever I choose as “format”, I’ll get a 
“.something” appended, but the response is still ok if I do 
'/cgi-bin/WebObjects/CloudManager.woa/ra/Status.json?type=heat” so that’s not 
an issue.

But the capital S and the plural do break my call, any idea about this?

Thanks, hope everything is as good as it could be in NYC,

Xavier

[ERRest] - Manually generating rest URL

[Dev WO via Webobjects-dev]

Hi everyone,

I’m currently trying a few things with ERRest.
In a stateless component, I need to create some urls manually (they will be 
used inside a script element).
When I was calling my DirectAction class, I was just doing this:

context().generateRelativeURLs();
NSMutableDictionary dict = new 
NSMutableDictionary();
...
dict.put(key, value);
...
String relativeUrl = context()._directActionURL(“myDirectAction", dict, 
false);


But I wasn’t able to find out the equivalent _directActionURL() method to 
generate the Rest (with /ra) URL.

How would you manually generate a relative URL for an ERRest request?

Thanks a lot and stay safe,

Xavier

Re: [Tomcat] -Classpath ordering issue (Dev WO)

[Dev WO via Webobjects-dev]

Hello Faizel,

Thanks a lot for this.
I was able to get back to this and made some tests. First, it’s clearly better 
when the context.xml file is in META-INF:)
I voluntarily made a typo in it and I was able to see that the file was 
actually checked by Tomcat.
I also tried to put things the other way around to actually create the issue on 
my test machine (Mac mini), but I wasn’t able to “break” it…
I thought that putting ERExtensions.jar in the PostResources would lead to the 
error I was getting on the other tests servers, but everything worked fine on 
the Mac mini. I wasn’t able to make it exhibit the failure from the other 
servers (NoSuchMethodError). I don’t understand that, and it feels like I can’t 
be sure it would work as expected on future deployment.

Any idea why I couldn’t create the error using the Pre/Post Resources (I’ve put 
all resources in their opposite directive)?
Any idea on how to make sure I can create (and so fix for sure) the error?

For now, I don’t have access to the other servers that were having the issue, 
but I used Matt’s tip (pre-expand ERExtensions.jar into /classes/…) and it was 
working. It’s just that I don't feel confortable keeping this solution as 
nothing tells me that classes folder loading won’t change in a Tomcat update…

Thanks a lot,

Xavier

Re: [Tomcat] -Classpath ordering issue (Dev WO)

[Dev WO via Webobjects-dev]

First, thanks a lot Matthew, that did the trick.

May I ask how you automate that for subsequent build?

I’m still trying to make the PreResources work without success so far. But I 
feel like it would be the most reliable way for futur version of Tomcat…

Thanks

Re: [Tomcat] -Classpath ordering issue (Dev WO)

[Dev WO via Webobjects-dev]

Hi Matthew,

I will try that.

Also I’m currently looking into using the PreResources feature like this:

-creating a directory mywebapp/WEB-INF/prelib with all the system jars (the 
Apple ones)
-mywebapp/WEB-INF/context.xml contains







but it doesn’t work for now. I also tried with an absolute path, but same 
failure ( java.lang.ClassNotFoundException for WOApplication)

Have you ever tried that way? any pointers?

Thanks,

Xavier

Re: [Tomcat] -Classpath ordering issue

[Dev WO via Webobjects-dev]

So far not good,

I’m trying to use the VirtualWebappLoader as below, but I’m not even sure my 
syntax is ok (and can’t find anything in the log relevant to this).
I “know” it doesn’t work as even with JavaWebObjects lib as the first one, the 
app still work on machine #2 (I would have expected a NoSuchMethodError 
exception)

I’ve also found jarjar (https://code.google.com/archive/p/jarjar/ 
<https://code.google.com/archive/p/jarjar/>) maybe creating a single jar with 
all of them inside might work, but I’m not sure how to use and to set an order 
for the jar…

Any pointer or sample code related to this lib ordering problem?

Thanks,

Xavier

[Tomcat] -Classpath ordering issue

[Dev WO via Webobjects-dev]

Hi WOers,

I’m starting to lost my mind with a Tomcat deployment (not my choice)

I have 4 machines:
1-Dev machine running through Eclipse and Apache (OS X) => Everything works
2-Test Tomcat deployment machine (OS X / Tomcat 9.0.29) => Everything works
3-Another test Tomcat deployment (Debian / Tomcat 9.0.20) => Everything works
4-Customer “beta test" machine (Debian / Tomcat 9.0.20) => Some part of the app 
doesn’t work

Of course machine #4 is the one I have the least access…

By "Some part of the app doesn’t work” I mean that I have some asynchronous 
thread that do their job, I have some HTML interfaces that works, but other 
don’t...
After way too much trial, I was able to get basically the same errors on my dev 
machine by changing the class path (moving down ERExtensions frameworks in the 
classpath). Finally getting errors like:

NoSuchMethodError: 
com.webobjects.foundation.NSArray.(Ljava/lang/Object;[Ljava/lang/Object;)V
and
NoSuchMethodError: 
com.webobjects.appserver.WOCookie.(Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;IZZ)V

After reading every thread about Tomcat from the mailing list from 2004 up to 
today, I still don’t get the issue.
I’m using the exact same .war file on all machines, with the web.xml relevant 
part (when framework order is correct) at the end of the message.

I have no clue and no idea regarding how to find the issue on this machine #4.

I’m using Wonder7 and WO5.4, the Application class extends ERXApplication 
(having JavaWOJSPServlet in the build path or not doesn’t change the fact it 
works on machine 1,2 and 3 but not 4)

Thanks for your help,

Xavier

[Tomcat] -Classpath ordering issue

[Dev WO via Webobjects-dev]

Hi WOers,

I’m starting to lost my mind with a Tomcat deployment (not my choice)

I have 4 machines:
1-Dev machine running through Eclipse and Apache (OS X) => Everything works
2-Test Tomcat deployment machine (OS X / Tomcat 9.0.29) => Everything works
3-Another test Tomcat deployment (Debian / Tomcat 9.0.20) => Everything works
4-Customer “beta test" machine (Debian / Tomcat 9.0.20) => Some part of the app 
doesn’t work

Of course machine #4 is the one I have the least access…

By "Some part of the app doesn’t work” I mean that I have some asynchronous 
thread that do their job, I have some HTML interfaces that works, but other 
don’t...
After way too much trial, I was able to get basically the same errors on my dev 
machine by changing the class path (moving down ERExtensions frameworks in the 
classpath). Finally getting errors like:

NoSuchMethodError: 
com.webobjects.foundation.NSArray.(Ljava/lang/Object;[Ljava/lang/Object;)V
and
NoSuchMethodError: 
com.webobjects.appserver.WOCookie.(Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;IZZ)V

After reading every thread about Tomcat from the mailing list from 2004 up to 
today, I still don’t get the issue.
I’m using the exact same .war file on all machines, with the web.xml relevant 
part (when framework order is correct) at the end of the message.

I have no clue and no idea regarding how to find the issue on this machine #4.

I’m using Wonder7 and WO5.4, the Application class extends ERXApplication 
(having JavaWOJSPServlet in the build path or not doesn’t change the fact it 
works on machine 1,2 and 3 but not 4)

Thanks for your help,

Xavier

Re: Extending the “No Instance Available” timeout

[Dev WO]

Hi Ben,

Your ping time isn’t the issue for sure, as far as I remember the time out is 
something like a minute…
I think the issue is more on the “application” side.
Try to see if you have anyway to get some log. Eventually output the SQL for 
your app to see if you forget to do some batch when accessing the database (if 
you see a row by row select, that is probably the primary issue to fix)
If it’s a Wonder app: 
log4j.logger.er.transaction.adaptor.EOAdaptorDebugEnabled=INFO either on your 
Property file or as a launch argument.

Re: [Google Chart] - Displaying chart in an Axaj Modal Dialog

[Dev WO]

You are right, it’s clearly more a regular ajax issue than a WO one, so I was 
already looking towards ajax related comment through a modal dialog.
Currently, the modal dialog get the correct string representation of the 
javascript function, and also gets updated correctly (like adjusting the date 
range to display the data).

I’m still investigating on the actual drawing of the chart. I’ve put the script 
function inside an ajaxupdatecontainer and try to use the onComplete which I 
though would be called when the content of the ajaxupdatecontainer is loaded, 
but that doesn’t seem to work as I get a javascript error “can’t find variable 
drawChart (the name of the js function). So I assume somehow it’s not fully 
loaded when the update container think onComplete should be called.

Anyway, this really seems to be a timing issue, I’m investigating this.

Thanks for your help,

I’ll try to update that thread if I can find a “nice” way to make it work.

 Xavier,
 
 There is maybe some other dependency or expectation about the execution 
 context in the graph library that break it outside the normal page rendering 
 process.
 
 You will need to trace or search on how to use this API inside a modal dialog 
 with AJAX contents. There is no real difference between using WO or any other 
 web server technology for these problems.

 Hi Samuel,
 
 I though I did that, but it looks like maybe not:)
 I may have been misled as I was actually displaying the graph inline on the 
 main content (to see if I actually got stuff to display), and also through 
 the modal dialog. When I removed the call in the main content, it wouldn’t 
 display in the modal anymore…
 So currently I’m generating the javascript inline within the main content, 
 and basically just call to draw it in the modal dialog. But I don’t like 
 that because I’m spending time generating the javascript chart directly 
 inside the main content when it may not get called at all.
 
 But I think the call to draw isn’t fully working (or maybe not at the right 
 time). Also I’m fighting with data format, it’s really more painful than I 
 though to use it.
 
 I’ll succeed eventually, but I’m not that confident it will be a “right way” 
 to do it;)
 
 Thanks for your tips,

 Your function drawChart is never called. I suppose 
 google.setOnLoadCallback(drawChart); add some sort of onLoad handler but 
 an Ajax request will never trigger it.
 
 A simple way that should work is to put a script after all the required 
 HTML elements for the graph with this content:
 
 script
 drawChart();
 /script
 
 There is probably another way with AMD call back but this is tricky since 
 the function drawChart does not exists when the AMD is created.

 Hi Samuel,
 
 I didn’t mention the console as there was nothing there.
 
 Let’s try to give more context:)
 
 I’ve got a component which is supposed to be the content of the modal 
 dialog, let’s call it “Chart”
 This component is
 wo:str value = $googleChartGenerationString escapeHTML = $false/
 div id = chart_points style = width: 1000px; height: 600px;TEST/div
 
 The $googleChartGenerationString generate something like this for example:
 script
 google.setOnLoadCallback(drawChart);
 function drawChart() {
 var data = new google.visualization.DataTable();
 data.addColumn('datetime', 'Date');
 data.addColumn('number', 'Points');
 data.addRows([
 [new Date(2015, 4, 3, 23, 44, 48), 1247],
 [new Date(2015, 4, 3, 23, 47, 43), 1247],

 var options = {
 curveType: 'none',

 width: 900,
 height: 500
 };
 var chart = new 
 google.charts.Line(document.getElementById('chart_points'));
 chart.draw(data, options);
 }
 /script
 
 If I’m placing this component inline in its parent component (which is 
 called via a regular component action, meaning the parent isn’t called 
 from an ajax request), everything is fine, the chart is displayed.
 
 If I’m placing the component in the “content” part of an AMD, I can see 
 that it still gets the expected content (using the browser console), but 
 nothing is displayed, even the “TEST” string isn’t removed which is also 
 why I think the javascript isn’t executed at all.
 
 So I’m kind of puzzled as to what could prevent my “manual javascript 
 from being executed when requested inside an AMD.
 
 I don’t really have much more context than this:(

Re: [Google Chart] - Displaying chart in an Axaj Modal Dialog

[Dev WO]

Hi Samuel,

I though I did that, but it looks like maybe not:)
I may have been misled as I was actually displaying the graph inline on the 
main content (to see if I actually got stuff to display), and also through the 
modal dialog. When I removed the call in the main content, it wouldn’t display 
in the modal anymore…
So currently I’m generating the javascript inline within the main content, and 
basically just call to draw it in the modal dialog. But I don’t like that 
because I’m spending time generating the javascript chart directly inside the 
main content when it may not get called at all.

But I think the call to draw isn’t fully working (or maybe not at the right 
time). Also I’m fighting with data format, it’s really more painful than I 
though to use it.

I’ll succeed eventually, but I’m not that confident it will be a “right way” to 
do it;)

Thanks for your tips,


Xavier

Re: [Google Chart] - Displaying chart in an Axaj Modal Dialog

[Dev WO]

Just a follow up, even if it’s not fixed yet.

The issue with the ajaxdatepicker is when the “underlying” page is scrolled, 
the calendar view is just nowhere near the field, it is there, but potentially 
out of sight.

I was able to display some graph by triggering the “onComplete” binding of an 
ajaxsubmitbutton, but so far I couldn’t get the graph to update (nor display at 
first).
Moving forward on this most probably very simple issue, but slowly:)

Re: [Google Chart] - Displaying chart in an Axaj Modal Dialog

[Dev WO]

Hi Ted,

Thank for the pointer, but I don’t think it’s the issue (I might be wrong 
though;))
I think my issue is more “how to make the JS to execute inside the modal body. 
The code is there, so it looks more like I’m not triggering the js correctly 
inside the modal…

 called via a regular component action, meaning the parent isn’t called from 
 an ajax request), everything is fine, the chart is displayed.
 
 If I’m placing the component in the “content” part of an AMD, I can see that 
 it still gets the expected content (using the browser console), but nothing 
 is displayed, even the “TEST” string isn’t removed which is also why I think 
 the javascript isn’t executed at all.
 
 So I’m kind of puzzled as to what could prevent my “manual javascript from 
 being executed when requested inside an AMD.
 
 I don’t really have much more context than this:(

 Xavier,
 
 Have look at the javascript console, if there is javascript error, it is 
 probably your problem. If there is nothing there, you should put way more 
 context to explain what you want to achieve and how you tried so far.

 Hi All,
 
 I’m trying to display a chart generated with Google Chart inside an AMD.
 
 For the Google Chart part, I’m generating a javascript function which is 
 then “written” into the HTML with a simple wo:string/escape=false directly 
 inside the AMD content.
 
 If I display it inline with the page, everything is fine. But if I try to 
 display it through an AMD, the javascript isn’t triggered at all.
 It is there, I can see the response (and it works inline for example), but 
 it doesn’t display/execute at all.
 I believe it’s not triggered at all because the js update the content of a 
 div, and when called through the AMD the “default content isn’t changed.
 
 I’ve tried using the afterLoad and afterResize bindings of the AMD to 
 trigger the javascript, but it doesn’t do anything.
 
 Anyone has any pointer on how to get my javascript executed inside the AMD?
 
 Thanks a lot,
 
 Xavier

Re: ERPDFGeneration problem

[Dev WO]

Hi Tim,

Maybe I'm all wrong, but you could check the Property of each .wo file (it 
should be inherited if the container is UTF-8 or manually select OtherUTF-8)
You could also check the corresponding .woo file and compare them with the one 
from the working component.

Re: What stands in the way becomes the way

Hi Aaron,

You did find something nice coming from France, lucky you:)

I was just telling my wife that I'd like to test that setup and I got you're 
fat enough, no way in response;) So guess I won't buy that French product for 
the foreseeable future.

WOWODC is clearly my best conference/community/favorite people, wherever will

 Hi Dan,
 
 I got it from the “Healthy Back Store” so I guess it’s ok ;-) I spend most of 
 my time in the “zero gravity” position.
 
 It’s kinda funny when you video conference with me. It looks like I’m on the 
 space station.
 
 Hahah, sometimes when people come to service the furnace, etc. they assume 
 I’m a vegetable. They have that look of pity on their face you know. Usually 
 I just go with it, have some fun.
 
 Actually, sometimes I move the chair and adjust the arm to use it as a 
 standing desk. Variation can be good.
 
 It comes from France, the brand is “La Fuma.” It should run around $150 USD. 
 It is meant to be an outdoor chair but I use it indoors. It’s a folding chair 
 that can be moved out of the way or taken with you. The “lacing” breaks every 
 6 months from daily use. It’s like a long shoe-lace. 
 
 It’s basically the poor man’s gravitonus:

Re: Opinions on static createŠ() methods for EOs

[Dev WO]

Someone will correct me if I'm wrong, but I think localInstanceIn is working 
only on an existing object in the datastore.
That means that if you create bar into ec2 and you try to do 
setBarRelationship(bar.localInstanceIn(ec1)) you will get a 
NullPointerException which could be difficult to track and debug if it happens 
in the eo class.

So I would recommend to not do it as a cross editingContext exception is 
easier to debug:)

 It is always safe to call localInstance.  My personal preference is to force

 references.
 
 Ah OK.
 
 I can also see the argument for “just do what is safest”.
 
 I hadn't thought of that benefit to leaving responsibility with the caller.  
 Anyway, I should pick one as I'm currently doing a bit of each with no 
 consistency.

You could overwrite (or create another) method fetchAllPaymentCustomers to

setIncludeEditingContextChanges(true)

I recall a discussion about this stating it was on purpose that Wonder

[Ajax] - Returning a file after ajaxlongresponse

[Dev WO]

Hello,

I'm having some trouble trying to return a file after an ajaxlongresponse.

I'm currently have my callable task used through ajaxlongresponse 
(CCAjaxLongResponsePage), I'm generating a woresponse (which is actually a 
file) then hand back this woresponse to the controller component (which is my 
regular page where I also initiate the longresponse from.
I'd like the file to be downloaded without user interaction at the end of the 
task, but so far I'm just able to get the response into my controller (so if I 
make another link on the page to download it works, but I don't want this extra 
step).

Any help would be great as I'm running out of ideas on this one:)

Thanks,

Xavier

Re: Intermittent hostname null in URL

This usually happens when you change IP address I think.

Re: Max Allowed Sessions

[Dev WO]

Hello Thomas,

I'm not sure if it's the right way to do what you want to do as I don't know 
exactly why you would do that:)
If you want to limit the number of users allowed, you should not rely on 
WOSession, as you could get a session when an exception is thrown, so you could 
basically end up not being able to handle even a single real user.

Maybe with more details someone could give you a better answer.

Re: Max Allowed Sessions

[Dev WO]

That was actually my point:
-you'd like to ensure that a maximum specific number of real user are using the 
system, you'll need to implement a couple things to actually define what is a 
user session and act on it
-you'd like to limit the number of WOSession your app instance is serving, you 
might have something available directly in Wonder

We'll dig in this deeper if the need ever arise;)

 Hello Xavier,
 thanks for your reply.
 
 we have no real problem at the time. This question is just for my own 
 interests ;-) I knew that i can easily define the time a session is alive. 
 And i'm now interested if there is a way to define a max number of allowed 
 sessions at a time (with the limit, that an single user can't login after 
 enough sessions are killed)

[Excel] - Excel generation slow when generating the NSData object

[Dev WO]

Hi List,

I've been doing some measurements regarding an Excel generation.
Almost everything is actually running as expected except when I create the 
NSData object using parser.data().
For example, up to this point of the method, it would take around 2-3 seconds, 
but then it takes around 300 seconds for the data() phase.
Is this something expected or is there something I could try to dig to find 
out why it takes that long?

I'm generating an Excel file which will be around 100KB with around 1000 rows 
and less than 10 columns.

Here's the code that generate it:

ExcelExport export = new ExcelExport(context());
export.setExcludeValidatedStrings(excludeValidatedStrings);

export.setExcludeNeedsValidationStrings(excludeNeedsValidationStrings);
export.setExcludeNeedsFixStrings(excludeNeedsFixStrings);
export.setExcludeGlobalKeys(excludeGlobalKeys);
export.setProject(selectedProject());
String contentString = 
export.generateResponse().contentString();
byte[] bytes;
try {
bytes = contentString.getBytes(UTF-8);
} catch (UnsupportedEncodingException e) {
throw new NSForwardException(e, Can't convert string to 
UTF-8...you should get a better VM);
}
InputStream stream = new ByteArrayInputStream(bytes);
EGSimpleTableParser parser = new EGSimpleTableParser(stream, 
(NSDictionary?, ?)data().valueForKey(Fonts), (NSDictionary?, 
?)data().valueForKey(Styles));
stream.close();
// Up to this point, things are going fast enough, around 3 
seconds

NSData data = parser.data();
// This takes ages, around 300 seconds

String fileName = ExcelExport.xls;
newResponse.disableClientCaching();
newResponse.appendHeader(String.valueOf( data.length()), 
Content-Length );
newResponse.setContent(data);
newResponse.setHeader(inline; filename=\ + fileName + \, 
content-disposition);
newResponse.setHeader(application/vnd.ms-excel, 
content-type);


Any pointer welcome:)

Thanks,

Xavier

Re: Relationship many-to-many issue

Your many-to-many model looks strange to me.
You shouldn't have the relationship listed in repartDomMatieres like that.
Try recreate your many-to-many using EOmodeler create relationship wizard.

Re: [Excel] - Maximum column with EGSimpleTableCreator

I've been nicely suggested to switch row/col as I wouldn't need 255 rows anyway.
But I'll try to keep this limitation in mind and see if I can work on it later.

 Maybe you could write an extension?
 Also the version of the poi-jar is out of date, 3.9 is the latest stable

 Looks like the SS Usermodel is a good idea.

Re: Relationship many-to-many issue

[Dev WO]

I may be wrong but I think you shouldn't have the relationship you have in your 
join table.
You should have only 2 in this table:
-a to-one to EOMatiere
-a to-one to EODomaine

your join-table doesn't really look like a join-table with all these 
relationships.

I would manually recreate every relationship

Re: Problems displaying Chinese in WO application

[Dev WO]

Hi,

The first thing you could check, is forcing the page to display as UTF-8 in 
your browser (usually through the ViewText Encoding menu).
If it displays the Chinese text correctly, it means you are missing a 
configuration somewhere:
-do you have something like meta http-equiv=content-type 
content=text/html;charset=utf-8 in your page HTML head section?
-Are you using Wonder? (it should default to UTF-8 I think or there's a 
property for that).

It shouldn't be a big issue, your setup seems pretty much as it should be.

Xavier



 Hi all,
 
 I'm writing an application that is translated into Icelandic, English and 
 Chinese.

 thor  | thor  | UTF8 | is_IS   | is_IS |
 
 I have _all_ of my project set to use UTF-8 as well.

 thor=# select * from onlanguagetranslations where key='log_in';
 id | lang |  key   | translation
 +--++-
 25 |1 | log_in |  24
 26 |2 | log_in |  25

 It's the first time I'm building RPM packages, so it might not be perfect,

Model/application development layout request for comment

[Dev WO]

Hi WOmates,

I'm actually rewritting a project to make it more multiple configuration 
aware.

I need to define a little more the multiple configuration setup:
-the same code-base will have about 10s different configurations (like language 
setup and custom UI layout)
-each configuration would serve in the range of 100s (maybe 1000s) users

My original idea was to create a single project in Eclipse and have a build.xml 
file for each configuration (providing the language(s), the database connection 
details, etc), that way I could have a specific database for each configuration 
and be able to update based on the configuration (like if configuration are 
used on different timezone, I can have a more optimized downtime window), in 
addition to isolate the data for each configuration.

I haven't completely look into the build.xml to see if I could use it to 
achieve per built Properties and includes for example.

But do you think it's the way to do it or is there a better way to manage this, 
mostly on the maintenance and future development perspective (having a single 
project seams pretty interesting to me)?

It shouldn't really matter for now, but it would also be my first move into 
D2W;)

Thanks for your comments,

Xavier

The browser is actually requesting pages based on language preferences (You can

Re: Multiple websites on Virtualized Server

[Dev WO]

Hello Gino,

I'm actually setting up a Linux virtualized server for WO (Debian).
I'm not done yet, but as far as your concerned, a virtualized server is just a 
server, it can have one or multiple IP addresses, but if you have 2 VM, you 
will have at least one IP (different) for each.
So it's basically like having a hardware server.

At least that's what I think, I may change my mind when I'm done;)

Just re-reading your question, each instance must have its own IP(s) like a 
real server.

Re: Concurrent request handling

 I don't think that will cause a deadlock.  It will cause some incorrectly

 As for the lockups, you really need to get thread dumps to assess those.  
 jstack is an easy way to do this.

 Don't Do Stupid Things  :-)  Which boils down to don't share objects that

 appropriate protection.  Global being either static members or instance

 common mistake.
 
 we inherited a project that has random (but infrequent) lockups and I found 
 that in the Application.java
 
 first there is an instance variable
 
 private NSNumberFormatter millionsFormatter;
 
 then a lazy initialization in the accessor method:
 
 public NSNumberFormatter millionsFormatter() {
   if (millionsFormatter ==null) {
 millionsFormatter = new NSNumberFormatter();
 millionsFormatter.setPattern(###,##0.00);
 millionsFormatter.setDecimalSeparator(,);
 millionsFormatter.setThousandSeparator(.);
   }
   return  millionsFormatter;
 }
 
 Could this approach be one of the causes of the lockups? The app runs in 
 multithreaded mode and there are tons of components with WOStrings bound to 
 this formatter...
 
 Thanks,

Re: Concurrent request handling

[Dev WO]

Hello Andrew,

 
 Hi Xavier;
 
 I would suggest not putting the formatter in the EO class because the EO is 
 model layer and the formatter really belong as part of the display logic -- 
 blurring the two eventually ends up causing design problems in the long-haul.

I completely agree with this:)

 I think in the past when faced with this situation, I added accessors to the 
 components' controllers' super-class which then gets or creates a formatter 
 for a particular purpose (data quantity format / timestamp / currency etc...) 
 which is cached in the user info in the WOContext instance for the current 
 request-response cycle.  This approach allows you to re-use the formatters 
 for the request-response cycle and then just allows them to be garbage 
 collected at the end of the cycle.

That means I would have as much formatter instances as there's a request for a 
specific component/page. It's probably not a big deal, it just feels strange to 
me to have something that is application-wide used in a component part.
Would it be a better practice to implement those formatter in a component 
super-class or have them as an interface for the components that need them?

Thanks,

Xavier


 
 cheers.

ERXObjectStoreCoordinatorPool, setting maxCoordinators higher than 1 result in unreliable synchronization

[Dev WO]

Hi all,

I've been looking into a synchronization issue with Wonder's ERJGroup (Wonder 
from 2011/01/29 with jgroups 2.6.8)
We use to set maxCoordinators=3 (maybe it was a default somewhere), but we 
experienced some unreliable synchronization between 2 apps (a back end and a 
front end). By unreliable I mean most things are working and some other (a 
lot less) are not working. It's always the same objects that either work or not.

So far, we were able to work around this issue by setting maxCoordinators=1, 
which seems weird to me.

Before I try to dig more into this, is there anyone using ERJGroup who already 
had to deal with something like this or has an input?

Thanks,

Xavier

Re: Horizontal inheritance mismatch between WebObjects 5.4 and 5.3 [ was: SQL generation doesn't conform to entity inheritance]

[Dev WO]

While working on getting this answered for you, I made a couple more tests and 
here is what I get:

-If I set an external name (Table Name) for the parents entities, the SQL 
generated with EntityModeler for the database creation is still wrong.
But entity.primaryKeyRootName returns CoreTable (which is the external name 
for Core)
And if I run the app, it actually run correctly, generating pKs from the 
CoreTable sequence

So it's kind of a no-issue, as long as you remember that EntityModeler won't 
create things correctly when you setup the database

-If I don't set an external name for the parents entities, the SQL generated 
with EntityModeler for the database creation is wrong.
And entity.primaryKeyRootName returns either Employee or Customer
And if I run the app, it breaks everything by requesting pKs from the 
sub-entities sequences

So I would say there's a bug in WebObjects 5.4 which you can get around by 
providing external name to parent abstract entities.
There's a bug somewhere else that lead EntityModeler to generate the wrong SQL 
when setting up the database.

So I guess it is solved or at least there's a way to make it work thanks to 
this really great community:)

Thanks,

Xavier

 I understand not everyone is using Horizontal Inheritance, but I

 Just to make sure, I've created a new Wonder framework, created only

 It looks to me this is a bug, I'm not 100% sure it's in Wonder or

Re: Horizontal inheritance mismatch between WebObjects 5.4 and 5.3 [ was: SQL generation doesn't conform to entity inheritance]

[Dev WO]

When I look at ERXModel, I only find
er.extensions.ERXModel.useExtendedPrototypes

I'm not sure that's what your talking about.

Is this supposed to fix the SQL generation from EntityModeler or prevent the 
bug at runtime (when there's no external name for parent entity)?

 The impl in 5.4.3 is wrong. Essentially 5.4.3 introduced a regression, 
 which I recall checking in a fix for in wonder, and I believe it's fixed in 
 5.4.3.1 :) like this:
 if (parent is abstract) {
   return my external name.
 }
 
 Which is just wrong. This was particularly a problem for Vertical 
 Inheritance where various fields ought to have resolved to the parent 
 entity's table (but didn't).
 
 I've never tested horizontal inheritance but you can fix it by:
 a) subclassing EOEntity and overriding primaryKeyRootName etc, or better
 b) use Wonder and if Horizontal Inheritance is a problem, fix it there for 
 all :)
 
 I'm using Wonder, I would have hoped whatever 5.4 bugs would have been fixed 
 already in this Wonder-ful frameworks:)
 
 I'm still digging right now.

Re: Horizontal inheritance mismatch between WebObjects 5.4 and 5.3 [ was: SQL generation doesn't conform to entity inheritance]

[Dev WO]

Hello Chuck,

With JavaERJDBCAdaptor or the default JavaJDBCAdaptor, the result is the same, 
it doesn't conform to the inheritance modeled in EntityModeler.
I've got to check into ERExtensions if I can find something.

I understand not everyone is using Horizontal Inheritance, but I must not be 
the only one trying to figure out what's going on with 5.4.

Just to make sure, I've created a new Wonder framework, created only an 
abstract entity and 2 sub-entities with horizontal inheritance, and the 
generated SQL is not correct, it doesn't conform to the modeled inheritance by 
requesting sequence for the pk for each sub-entity instead of the abstract 
parent sequence.
It looks to me this is a bug, I'm not 100% sure it's in Wonder or Webobjects 
though. Should I fill a Jira for this? I don't think this could be qualified as 
a regression as I don't even know if this bug was ever in 5.3.

Thanks for your help,

Xavier

Re: Horizontal inheritance mismatch between WebObjects 5.4 and 5.3 [ was: SQL generation doesn't conform to entity inheritance]

[Dev WO]

Sure Dave, here they are:

parent entity
{
attributes = (
{allowsNull = N; name = id; prototypeName = id; }, 
{allowsNull = Y; columnName = name; name = name; prototypeName = 
varchar255; }
); 
attributesUsedForLocking = (id); 
className = com.anazys.tempFrameworkWonder54.Core; 
classProperties = (name); 
fetchSpecificationDictionary = {}; 
isAbstractEntity = Y; 
name = Core; 
primaryKeyAttributes = (id); 
}

subclass Employee
{
attributes = (
{allowsNull = N; name = id; prototypeName = id; }, 
{allowsNull = Y; columnName = name; name = name; prototypeName = 
varchar255; }
); 
attributesUsedForLocking = (id); 
className = com.anazys.tempFrameworkWonder54.Employee; 
classProperties = (name); 
externalName = Employee; 
fetchSpecificationDictionary = {}; 
name = Employee; 
parent = Core; 
primaryKeyAttributes = (id); 
}

subclass Customer
{
attributes = (
{allowsNull = N; name = id; prototypeName = id; }, 
{allowsNull = Y; columnName = name; name = name; prototypeName = 
varchar255; }
); 
attributesUsedForLocking = (id); 
className = com.anazys.tempFrameworkWonder54.Customer; 
classProperties = (name); 
externalName = Customer; 
fetchSpecificationDictionary = {}; 
name = Customer; 
parent = Core; 
primaryKeyAttributes = (id); 
}


I could edit the code for the SQL when generating the database, but the issue 
is really in production, if I update the app, it will start to generate pk 
based on the sub-entity, and I will end up with duplicate pks between various 
sub-classes.
So the SQL generated by EntityModeler is just a way to check if it's going to 
break the current app, not really for that specific action.

 What if you manually create the database tables and the sequence instead of

 see what entity.primaryKeyRootName() returns for each of the entities 
 involved ...
 
 actually on your abstract entity, did you set an external name? make sure you 
 set that -- external name on the root entity is what is used in 5.4.3 to 
 determine what sequence to generate.

I was about to try this, but actually, where did you set the external name in

 It might be that few people are using Horizontal Inheritance.I

 Based on your evidence, I'd search for primary in ERExtensions.  If 
 nothing else, that will at least show you were in EOF the PK 
 generation  happens.

[Dev WO]

Hi David,

 Hi Xavier,
 
 Hmmm. As a complete aside to the SQL generation issue, are you _sure_ you 
 need inheritance for this?
 
 In your app, what happens if an employee wants to buy something from you? 
 They can't be both a customer and an employee. Don't make the mistake of 
 thinking you can change change which class a person is.
 
 Using inheritance in this type of situation is almost always the wrong way to 
 go. I'd probably model this as a person being able to have multiple roles and 
 you'd get all the customers by doing something along the lines of Get all 
 person objects that have relationship to the customer type. In Wonder: 
 
 NSArrayPerson customers = Person.fetchAll(ec, 
 Person.ROLES.contains(Role.customerRole()));
 
 You can then have different behaviors for different roles by using delegates 
 that encapsulate the role-specific behaviors. Replace the idea of IS-A 
 (person) with HAS-A (role).
 
 Much more flexible, and it gets rid of Inheritance in your EOModel.

I totally agree that this specific example is not really interesting, but it 
was just to showcase the issue.
But I do use quit a lot horizontal inheritance, for products in an online 
store, etc. I just can't get rid of them. Some projects are just in maintenance 
mode, we won't rewrite them at such a lower level. New projects are using less 
horizontal inheritance, but still some;) So I have to figure out how to fix 
this 5.4 feature;)

 I could edit the code for the SQL when generating the database, but the 
 issue is really in production, if I update the app, it will start to 
 generate pk based on the sub-entity, and I will end up with duplicate pks 
 between various sub-classes.
 So the SQL generated by EntityModeler is just a way to check if it's going 
 to break the current app, not really for that specific action.

 What if you manually create the database tables and the sequence instead of 
 letting EntityModeler generate the SQL for them? Does creating and saving 
 new instances of the subclasses work? What I'm trying to figure out is if 
 this is a problem with just the Create Table statements generated by the

 With JavaERJDBCAdaptor or the default JavaJDBCAdaptor, the result is the

 I've got to check into ERExtensions if I can find something.
 
 I understand not everyone is using Horizontal Inheritance, but I must not 
 be the only one trying to figure out what's going on with 5.4.
 
 Just to make sure, I've created a new Wonder framework, created only an 
 abstract entity and 2 sub-entities with horizontal inheritance, and the 
 generated SQL is not correct, it doesn't conform to the modeled 
 inheritance by requesting sequence for the pk for each sub-entity instead 
 of the abstract parent sequence.
 It looks to me this is a bug, I'm not 100% sure it's in Wonder or 
 Webobjects though. Should I fill a Jira for this? I don't think this could 
 be qualified as a regression as I don't even know if this bug was ever in 
 5.3.

 The impl in 5.4.3 is wrong. Essentially 5.4.3 introduced a regression, which 
 I recall checking in a fix for in wonder, and I believe it's fixed in 5.4.3.1 
 :) like this:
 if (parent is abstract) {
   return my external name.
 }
 
 Which is just wrong. This was particularly a problem for Vertical Inheritance 
 where various fields ought to have resolved to the parent entity's table (but 
 didn't).
 
 I've never tested horizontal inheritance but you can fix it by:
 a) subclassing EOEntity and overriding primaryKeyRootName etc, or better
 b) use Wonder and if Horizontal Inheritance is a problem, fix it there for 
 all :)

I'm using Wonder, I would have hoped whatever 5.4 bugs would have been fixed 
already in this Wonder-ful frameworks:)

I'm still digging right now.

 I'll will update WOLips right away to check if it changes anything, but if

 I am revisiting some old EOF documentation and wanted to make sure I 
 understood a few things. Are the following statements true?
 
 
 *   When an EOModel is found and connected to a database when the app

 I think that EODatabaseContext is more correct than EODatabaseChannel.  The 
 context will then use the channel.  A db context can handle multiple models 
 (the connection information needs to be the same).
 
 How can single db context handle multiple models ? I see that
 EODatabaseContext.forceConnectionWithModel(model,cd,ec)
 returns different objects for different models, whereas most of my
 models point to the same database with the same connection dictionary.
 And would it make sense to somehow force all these models to single db 
 context?

If you are using Wonder, you could use the following in your Properties file
## Class name to use instead of the JDBCAdaptor, the ERXJDBCAdaptor supports
## connection pooling
er.extensions.ERXJDBCAdaptor.className=er.extensions.jdbc.ERXJDBCAdaptor


 
 Is there a default number of EODatabaseChannels opened when the app starts 
 up? Is there a configuration setting that I can set to add more?
 
 One per db context and no.
 My problem is that I see my app opening more connections than a number
 of models it has.
 And those connections do not close even after more than an hour not
 used. And it does not reuse all of them for later requests but may
 create even more connections.
 As a result when running multiple instances on a server with limited
 DB-connections I do get too many connections error sometimes.
 
 How could I fight it? Is it possible to control the number of open
 connections and close unused ones after certain idle time?

Can't respond on this one, but the property above should fix all this.

Re: [OT] Apache rewrite rule

On your server you may have virtual host setup, so the rewrite rule has to be

 er.extensions.ERXApplication.replaceApplicationPath properties, but I get the

 rewrite.log file.  Is there some other property to set in httpd.conf or 
 elsewhere?

Re: Oracle EOModel connection [Solved]

[Dev WO]

Oups forgot to reply all

Actually it went pretty smoothly.
I added the jdbc connector ojdbc14_10203.jar
I didn't need to fill the Driver and PlugIn name in EntityModeler.

The only issue I had was that the SQL was requesting uppercase variable names 
and it would work as it was lowercase in the database (it was a View, not a 
real database).
I didn't take the time to search for the uppercase issue as it was easy to 
change directly in the View.

Thanks Pascal and Chuck for your help, I was able to deliver on time and fully 
functional;)

 If there is a driver in the Java Extensions directory of the machine you run

 driver is the fully qualified class name of the main class of the JDBC

Oracle EOModel connection

[Dev WO]

Hello,

I have to connect to a remote server hosting an Oracle 10g database. More 
precisely, the server is:
OS: linux RedHat X64
DB:Oracle 10G standard One

It seems the URL to enter in the EOModel would be:
jdbc:oracle:thin:@IP_ADDRESS:PORT:DATABASE

I'm not really used to connect to either Oracle or remotely. Does this sound 
good to you? I'm also usually use / in my URL, so the : makes me wonder if 
there's something I should know about...

In addition to that, I added the following frameworks to my project (I'm using 
Wonder and ERPrototypes):
JavaERJDBCAdapator
EROraclePlugin

What would be the name to fill for the Driver and PlugIn in EntityModeler?

Thanks for your help, I'm not changing database often enough;)

 I'm not really used to connect to either Oracle or remotely. Does this sound 
 good to you? I'm also usually use / in my URL, so the : makes me wonder 
 if there's something I should know about...
 
 Can you connect with other tools, like Oracle SQL Developer? It might be a 
 network problem (wrong routes, firewall, etc.)

Actually I'll be able to connect (and deploy) tomorrow and it has to work right 
away;) It's a really small stuff, but I wasn't really expected : but if you 
have the same for you, it might be good:)

 In addition to that, I added the following frameworks to my project (I'm 
 using Wonder and ERPrototypes):
 JavaERJDBCAdapator
 EROraclePlugin
 
 What would be the name to fill for the Driver and PlugIn in EntityModeler?

I'll be happy to have your input on this one:)

Thanks Pascal,

Xavier

Re: Oracle EOModel connection

[Dev WO]

Hello Chuck,

I'm making a fully embedded app, so I think I have to get/add a specific jdbc 
driver (I'm still wondering which name to put for Driver and PlugIn in 
EntityModeler or if it's not relevant).
I think I should use the Release 2 for the following page actually:
http://www.oracle.com/technetwork/database/features/jdbc/index-091264.html

Am I correct?

Xavier

[OT] - WWDC10

[Dev WO]

Hello womates,

just in case there are some of you with a still working ADC Premium with an 
e-ticket for WWDC2010 and they won't attend, maybe those tickets can be of help 
for some of us:)
Basically it could be a list of everyone who are going to attend and the 
number of available tickets. We could put that all together and see how much 
we need to add to get tickets for all the attendee.
If there's only a couple of e-tickets available I vote for giving it to the 
oversea active person on the list like Anjo for exemple.

I think we need to move fast, tickets sold out really quickly last year.

Re: announcement

June 2123, a couple days before WWDC '123, Mike The Unstoppable Code Machine 
Schrag passed away.
Using WebObjects, Wonder and WOLips, he was able to last more than any other 
software-enhanced humans (namely phpmen and railsmen).
We will miss his craziness, friendship and community contributions.

Congratulations Mike, I'm sure you'll still be active in this mailing list. 
It's a good opportunity to also thank all the other contributors (I won't name

See you at WWDC '10.

Re: Server Redundancy for WO Apps

[Dev WO]

Hello Gino,

If you'd like to be able to failover either a service or a server, you will 
have to go through the data synchronization issue.
I think synchronizing things are really hard, like web server resources, 
databases etc. So the first step would be to get the data storage out of the 
Xserve.

Here's what we have done, it may not be exactly what you are looking for, but 
it should give you some clues:
-We invested in a Promise Vtrack and Xsan to get a clustered filesystem, so 
every xsan clients (which are only xserves) can access the external storage all 
the time
-We symlinked the database, the webserver folder and the webobjects folder into 
the Xsan storage, that way, everything is already external to each xserve
-You could even go as far as symlinked your config files for Apache, wotaskd, 
etc but it means you won't be able to load balance between servers (at least 
not with global config files) which may not be an issue

You would still get downtimes with this setup mainly because of DNS, as it may 
take some time to update the records to the failover xserve, but the failover 
xserve could do other services, it will only be a little more loaded if the 
first one fail.

If you want zero downtime, you could setup something like this, you would need:
-3 xserves
-1 Promise vtrack
-Xsan

Xserve A would be the meta-data controller for Xsan and also an Open Directory 
replica
Xserve B would be your main server with all the services, but every data and 
config files would be symlinked onto the Xsan volume (it would be good if it is 
also a secondary metadata controller)
Xserve C would be setup as a failover server, so it would take the IP of Xserve 
B in case of failure, and as all the data are on the Xsan volume, it should 
work smoothly

Xserve C can't do anything, it will only be able to get B services if it fails, 
and do nothing if everything is working on B.

The biggest psychological issue I add to go through when we setup our Xsan grid 
was to accept to have an Xserve dedicated to nothing (just providing the 
clustered metadata to the clients)... and in the setup above, you would even 
get only one Xserve out of the 3 which is actually doing something.

But you would get a great deal of uptime availability.

Xsan, with the fiber switch and the complete setup is expensive, but it may be 
worth it for the targeted availability.


Anyway, one of the first step for high availability is getting every data 
external so another server could access them.


I hope it gives you some pointers,

Xavier


 Hi there..
 
 Maybe this is a little off list as its not a development question
 But I have a main Xserve running about 10 Apps for clients and there has been 
 various outages caused by DNS, Hard Drive or Power failures occurring 
 infrequently but enough to cause concern.
 
 Does anyone have any advice how to set up a redundant server/service and what 
 are the implications?
 ie Files needed instant transfer to redundant server instantly (or 
 periodically) and how to switch between them in cause of failure.
 
 Any help or being pointed in the right direction appreciated.
 
 Gino

Re: Troubleshooting utf8 text SQL generation

[Dev WO]

Hello Kieran,

Someone will probably come up with an alternative, but I've never  
been to be able to make blob work the way I wanted with UTF-8. I had  
to convert my blob to mediumtext.
As far as I know (but I'm not a db expert;)) blob can't have an  
encoding like a mediumtext for example.


Xavier




I have a text blob attribute defined as
External Type : TEXT
Data Type : UTF Character Stream - String E

EOF is treating it as binary in the SQL generation, so I get this:
... UPPER(T3.textobject) LIKE UPPER(_binary'%argentina%') ...

instead of this which is what I should expect??
... UPPER(T3.textobject) LIKE UPPER(_utf8'%argentina%') ...


I am using MySQL. My connection string is:
jdbc:mysql://localhost/omega?useUnicode=truecharacterEncoding=UTF-8

and the table is defined as:
CREATE TABLE `textblob` (
  `oid` int(11) NOT NULL,
  `textobject` text,
  PRIMARY KEY  (`oid`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

Am I correct in thinking I should not be getting _binary before the  
search term?

Re: WOPopUpButton bug 5.3 DST : SOLVED

[Dev WO]

Hello Olav,



Hi,

Just to follow up regarding the escaping problem.

It turns out using:

String aURL = context().directActionURLForActionNamed(resolve,  
queryDict());


Will return an escaped string like so:

/WebObjects/Resolver.woa/wa/resolve? 
catId=1001249amp;ni=yamp;sort=ddown


This behavior is new since 5.3 I guess.


I think it was corrected in 5.2.x I filled a bug report to get the  
 escaped (it's not standard compliant if they are not escaped).




And I actually want:

/WebObjects/Resolver.woa/wa/resolve?catId=1001249ni=ysort=ddown


Well no, it's not what you want;) you want the  escaped, this is how  
it has to be:) Try to use your application you'll see it's working  
with the amp;
If you look at the status bar in you web browser, you won't see the  
amp; pour only  and if you activate the link you'll also get an   
in the address bar instead of the amp;. This is the expected  
behavior, you shouldn't have a non-escaped  in a url.


So I have to run the returned string through an unescaping routine  
to get the above uri.


Once I did that everything works fine.
Are you sure it wasn't working with the amp;? if it didn't it's a  
bug somewhere else, not the amp;



Hope this helps someone else.

Regards,

Olav

Hey,

I just upgraded to 5.3 DST from 5.2 and noticed a bug in the  
WOPopUpButton component.


I'm sending down a url as a value and it get double escaped like  
so:


option value=/WebObjects/Resolver.woa/wa/resolve? 
catId=1001221amp;amp;ni=yamp;amp;sort=ddown#1001221/ 
WebObjects/Resolver.woa/wa/resolve? 
catId=1001221amp;ni=yamp;sort=ddown#1001221/option


Notice the two amp;amp; ?

That's the first amp being escaped.


Has anyone else experienced this problem?

Thanks!

Hey,

I just upgraded to 5.3 DST from 5.2 and noticed a bug in the  
WOPopUpButton component.


I'm sending down a url as a value and it get double escaped like so:

option value=/WebObjects/Resolver.woa/wa/resolve? 
catId=1001221amp;amp;ni=yamp;amp;sort=ddown#1001221/WebObjects/ 
Resolver.woa/wa/resolve? 
catId=1001221amp;ni=yamp;sort=ddown#1001221/option


Notice the two amp;amp; ?

That's the first amp being escaped.


Has anyone else experienced this problem?

Thanks!

Re: WOPopUpButton bug 5.3 DST

[Dev WO]

This is just my point, but you should never have a form without a  
submit button.
Javascript is good only if it works all the time (meaning every  
browser) and if thing's still work without it. It should only be to  
get more, but never to prevent the site from being navigated.
If you'd like to make something auto-submitting and hide the button,  
but still work if javascript is not available, you just need:

-in your select:  onChange=this.form.submit()
-then a script/noscript part:
---
script type=text/javascriptinput type=submit  
value=Rechercher name=searchinput type=hidden  
name=WOSubmitAction value=search/script
noscriptinput type=submit value=Rechercher  
name=searchinput type=hidden name=WOSubmitAction  
value=search/noscript

---

The submit in the script part is hidden using a css rule
The submit in the noscript part will be displayed if javascript is  
disabled, so the user can still submit the form


Hope this help;)

Xavier




Hey Xavier,

Thanks for the info.

I'm using the value binding in conjunction with javascript to allow  
users to navigate to other parts of the site without using a submit  
button.


Like so:


menu: WOPopUpButton {
list = category.parent.newContentSubCategories;
item = categoryItem;
value = activeContentLink;
displayString = categoryItem.nameWithUnreadItemsCount;
noSelectionString = noSelectionString;
name = menu;
	onChange = location.href=(menuform.menu.options 
[menuform.menu.selectedIndex].value);

escapeHTML = false;
}

Hi Olav,

It's not related to DST update. I think it appears in the 5.3.x  
but I'm not completely sure.
It's a but when using the href binding, but I don't understand  
why you have a hyperlink in an option value, maybe it's just a  
test you made.
Anyway, search the list for bozo ampersand you'll find some way  
to get around this (Daniel Muller, WebObjects 5.3.1 Redirect Bug  
- 17th february 2006)


I'm pretty much never use the href binding and instead use the  
directaction bindings, but maybe someone using Wonder frameworks  
can confirm if Wonder also experience this bug.

If it's not the case, you could link to Wonder frameworks.

Re: RSS Feed

[Dev WO]

Hello Bruno,
the first icon (the one you get) is just saying your page is a XML  
page and if you click on that icon, you could go back to the html  
page from which the like to the XML is displayed (this page may not  
exist of course)


Just try with a regular website for example:
http://www.macosx86.net
you'll get the white text on blue background when you're on the  
HTML page, and if you click on the icon you'll get the RSS feed with  
blue text on white background


Xavier




Hello,

After creating XML page, I get this icon in the address bar
rssIcone.png
 instead of the other one
Image 1.png
Can anyone tell me why ?

Thank you.

Data freshness and inter-applications/instances notification

[Dev WO]

Hi list,
it's been some time without a data freshness question:)

I've been reading the list and Practical WebObjects book to get as  
much details as I can, but I just can't find the solution I'd like.
Here's a quick summary of the project related to this, it may give  
you a better understanding about my goals:
-Actually there are 2 WOApplications (Front Office and Back Office)  
and a Framework (with the eomodel)
-In the FO, I'm using the sharedEditingContext to initialize some  
entities. I've got multiple initializeList method to be able to  
invalidate only specific lists when needed.
-The FO answer to some DirectActions which lead to a new  
initialization for a specific entity (I'm using  
InvalidateObjectsWithGlobalIDs, it seems to invalidate correctly all  
the relationships of the entity)
-In the BO depending on the object edited/added/deleted a call to one  
of the specific FO DirectAction is triggered.


The deployment is only one instance for each (1 FO and 1 BO) for now,  
and because it doesn't work with multiple instances;)


This setup allows me to get fresh data every time there's a fresh  
data to display, immediately, and basically down from 2 request  
per day on the DB to about 100.


But this is not as good as it seems...
There are 2 different things I'm looking at:
A-making this work with 2 or more instances of the FO
B-making a change to the FO (yes FO user can also add things to the  
DB) be populated to all the FO instances


Regarding A, I was looking at the NotificationFramework of Project  
Wonder, but if I red correctly is not really efficient if the  
application has a lot of request (I know this one doesn't).
So I was thinking I could issue a grep command to get the list of  
running instances, then issue a specific DA request for each instance  
(actually there's no callback feature so I don't know if the  
instance got the notification and behave as expected), or maybe I  
could use some code from WOMonitor to get the instance numbers for a  
specific application.


What's your opinion about this? maybe (most probably) there's  
something better than this I didn't find;)


Regarding B, FO user can post comments, they can't edit anything only  
add things.
This is a news system, so I really need people to be able to see  
any comment posted as soon as it is posted. It works for now as  
there's only one instance and I'm using a specific ec to add the  
comment (set the sharedEC to null) so the sharedEC reflect the  
changes immediately.
But if I have multiple instances, I got mixed up result as the new  
comments only updates their own instance...So I've got to find a way  
to notify all running instances of the modifications.

Any pointer about this one?

My knowledge of EOF underlying layers is clearly lacking a lot of  
things, if someone feel I need to read a couple things about it,  
don't hesitate to mention what I should read;)


Thanks for sharing your knowledge:)

Re: Any way to make ERXLocalizer work with UTF-8?

[Dev WO]

Hi Helmut,
first, try to encode your .strings files as UTF-16.
At least on Xcode, UTF-8 will lead to trouble.

If it doesn't fix your issue, I'll provide you with what I'm using to  
get it to work (it mostly work;))


Xavier




Hi,

is there any way to make ERXLocalizer work with UTF-8? I have my  
Localizable.strings files UTF-8 coded, but I didn't find a way to  
tell ERXLocalizer which encoding should be used. So all of my  
string bindings are corrupted if some special characters are used.


Regards,
Helmut

EOSortOrdering based on a @count relationship

[Dev WO]

Hi,
I've been trying to isolate the issue with this, but I just can't  
even get an error...
So I need to sort based on a calculated attribute: relationship 
().count()


but I just can't make it work...

I've got entity a which has a toMany relationship relationship().
I need to sort a entities based on relationship().count().

So here's my SortOrder:

public Number numberOfComments() {
return (Number)writeCommentaries().count();
}

public NSArray sortOrderingByCommentaries() {
NSMutableArray sortOrdering = new NSMutableArray();
		EOSortOrdering newSO = EOSortOrdering.sortOrderingWithKey 
(numberOfComments, EOSortOrdering.CompareDescending);

sortOrdering.addObject(newSO);
return (NSArray)sortOrdering;
}


and the actual sorted array:

public NSArray listOfNewsSortedByCommentaries() {
		return (NSArray)EOSortOrdering.sortedArrayUsingKeyOrderArray 
(listOfNews(), new NSArray(sortOrderingByCommentaries()));

}


but it won't work, I don't even get a crash, just a no instance  
available...
I tried with another Number attribute to see if it coud be the cause,  
but it works. I also sort using another attribute and display the  
relationship().count() for each a and it works. It seems I just  
can't sort using the relationship().count().


But I though I could use custom attribute as long as the array is  
already in an editing context.


I must miss something, but I can't find it...

Thanks for your help

[OT] Entity Modeler, how to create a many to many

[Dev WO]

Hello,
I've been trying to work with Eclipse/WOProject for my latest  
project, and it seems I can make it:)


But actually I'm stick on something which might be obvious: creating  
a many to many relationship in Entity Modeler.


I used to have to select the 2 entities in EOModeler and do join in  
many to many, but I can't find where's that feature in Entity  
Modeler...
I know I could create the join table, etc but I think I recall a demo  
of EM at WWDC by Mike Schrag doing something like this...but maybe  
I'm wrong.


Could someone tell me how to make a many to many using Entity Modeler:)

Thanks

Xavier

And your recall would be right :)

Actually, the latest builds have a much fancier relationship  
dialog, so you might want to upgrade to get all the relationshippy  
goodness if you haven't already.


If you select two entities in the entity tree (outline view), you  
can then click the New Relationship action and it will bring up  
the New Relationship Dialog.  I love the new versions of this  
because it even has an option to add the foreign key attribute for  
you, too, for non-many-to-many's (though I don't recall what it  
does if you don't use Project Wonder -- it uses prototype 'id' when  
you have Project Wonder).


In the dialog, you can select which sides (or both) of the  
relationship are to-many, you can name the relationships, you can  
optionally have it create a foreign key attribute for one-to-many  
(single foreign key), or you can select the join attributes.

Importing CSV into a WO application

[Dev WO]

Hi,
searching the list I have found many post about excel export and  
things like that. But I'm actually looking for a way to import CSV  
into a WO application.


Is there anything already done to handle importing of CSV?

Like providing a NSArray of column name, an editing context and an eo  
to match the value to?


Thanks

I found the link to ostermiller's site but it was down when I checked;)
Thanks Kieran, I'll have a look.

You can use utilities such as this:
http://ostermiller.org/utils/CSV.html

 and wrap the parser with your own utility classes to do what  
you want.


/** @return NSArray of strings when passed a line of CSV data */
public static NSArray arrayFromCsvRecord( String csvRecord ) {
String[][] fieldValuesParsed = CSVParser.parse( csvRecord );
return new NSArray( fieldValuesParsed[0] );
}

Just a quick question, if it's provided as a service and not as a

faultWithPrimaryKeyValue, make sure it only returns a fault

[Dev WO]

Hi,
I'm using faultWithPrimaryKeyValue to access an eo in a sharedEC.
I was using it thinking it would return only faulted eos in the  
sharedEC, but after reading the java doc again, I think it may do a  
fetch to access the object (if not available in the fault).


So my issue is that I'm fetching object in the sharedEC with specific  
parameters, but when I request an object through  
faultWithPrimaryKeyValue, I can access object that doesn't conform to  
the sharedEC specific parameters.


For example, I can have an attribute available (boolean) on my  
object and only put the ones with available=true in my sharedEC. But  
I can still acces all the objet through my specific action using  
faultWithPrimaryKeyValue which is not what I want:)


Is there a way to request only a fault from a specific ec?
Or do I have to test for the specific attributes after I get the  
object? (If I can avoid this, it is really nice:))


Thanks

Re: Sending a request to a url but not returning the page to the user
