Re: Next step: running complex queries that return counts

[CHRISTOPH WICK | i4innovation GmbH, Bonn]

Hi Ken,

I'm using EOUtilities.rawRowsForSQL

Here's an example from my code

> public int numOfTotalMessages(EOEditingContext ec) {
>   String sqlTerm = "SELECT COUNT(*) FROM PMSMessage WHERE ownerUserID = 
> "+this.primaryKey();
>   NSArray resultsRows = EOUtilities.rawRowsForSQL(ec, "PMSModel", 
> sqlTerm, new NSArray("count"));
>   return ((Number) ((NSDictionary) 
> resultsRows.objectAtIndex(0)).objectForKey("count")).intValue();
> }

It takes 4 params:

1. an EOEditingContext. Take one you already have or create a new one.
2. the "name" of your model as String.
3. a SQL term. Just write plain SQL or even MySQL dialect (if you use MySQL 
only)
3. an array of key-names that are used in the dictionaries returned. In case of 
a count-query, it's pretty useless, since you get exactly one result row with a 
one-line dict.

OK?

Re: Extending the "No Instance Available" timeout

[CHRISTOPH WICK | i4innovation GmbH, Bonn]

My understanding is that a "No instance available" comes from your Apache's 
WOAdaptor. Therefore it shouldn't basically have nothing to do with your VPN or 
slow internet connection.

Daniele has already suggested using a ERXLongResponsePage.

Sometimes the problem is not a single database operation, but a WORepetition 
iterating over a huge array of objects and then - inside the WORepetition - 
calling another db/eof-intensive method on each item, like e.g. 
'item.littleDatabaseWork()'.

While each 'item.littleDatabaseWork()' may only take some ms, iterating over a 
lot of items may be too much. In this case, 'pagination' of large arrays may be 
the best solution. Use a ERXDisplayGroup in this case.

Re: slooow DB access at the deployment site (was: relationship count without fetching)

[CHRISTOPH WICK | i4innovation GmbH, Bonn]

Hi OC,

I once had a deployment machine with FrontBase on which – I don't remember why 
anymore – the indices of the tables where not set. The database was working but 
it was very very slow. After generating the indices and setting the index mode 
to "preserve time" the speed was back as expected.

So maybe you take a look, if your indices are set up correctly.
(In FrontBaseManager go to "Schema Objects" -> $USER -> "Tables" -> $TABLENAME 
-> click "OPEN DEFINITION"-button -> "Index")

Re: ERPDFWrapper unicode characters

[CHRISTOPH WICK | i4innovation GmbH, Bonn]

Hi Stavros,

I have ERPDF working with german umlauts (äöü...) pretty well, so I think it 
basically works with UTF-8.

Just two simple questions:

1. if you set the "enabled" binding of ERPDFWrapper to "$false", do you get a 
(html) page with greek characters? If not, your problem may not be ERPDF, but 
probably your java or whatever.


2. does the  section of your HTML inside ERPDFWrapper contain something 
like



I'm not 100% sure anymore, but I think it's necessary.

ERCaptcha with Java 1.8 shows black image only

Hi List,

has anyone running ERCaptcha with Java 1.8 successfully?

All I get is a black image when running Java 1.8 - in a project that works 
perfectly on my other machine with Java 1.7.

I found this on StackOverflow:

> This JCaptcha library is really old, and going by the state of their code 
> repository, it is an abandoned project. The problem with this library is that 
> it uses very specific version of JH Labs Image filters for CAPTCHA image

(s. 
http://stackoverflow.com/questions/22894510/jcaptcha4struts2-plugin-image-not-loading)
 This may be something completely different, but it’s the best hint I found so 
far.

Any hint appreciated.

Re: Odd backtracking error

Hi Mark,

if you are using the new window to show a PDF (which should not have any 
further links or buttons), it may be a better solution to use a direct action 
to show it and pass all necessary params to it.

 I’m not sure this would explain everything you’re seeing here, but you can 
 get session loss (and the resulting unexpected bounce to a login page) 
 when using cookies for session ID storage if 
 WOSession.domainForIDCookies() is returning something “too specific” for 
 your deployment setup. By default, that method returns the application’s 
 full path, right down to the “.woa” extension. So, for example, if you’re 
 using URL re-writing in deployment, there could easily be a mismatch. I 
 usually override it to return “/”. Again, not sure it explains everything 
 you’re seeing there, but it’s something to rule out.

Re: velocity or.....for templates?

[CHRISTOPH WICK | i4innovation GmbH, Bonn]

Hi Tim,

if you're are using Wonder, it seems obvious to me to use WOComponent as a 
template engine.

1. define your component as you do with normal wocomponents

2. Instantiate like this:

YourMailComponent mailComponent = (YourMailComponent) 
ERMailUtils.instantiatePage(your.app. YourMailComponent.class.getName(), null);
mailComponent.setBinding1(binding1Value);
mailComponent.setBinding2(binding2Value);
String htmlOfYourMailComponent = 
mailComponent.generateResponse().contentString()

there a way to generate the WOContext outside the RR-Loop?

Re: Catching ERXAttachmentExceedsLengthException

[CHRISTOPH WICK | i4innovation GmbH, Bonn]

Hi Miguel,

AFAIK (and I even wrote a mail to Mike Shrag, who wrote this code) there is no 
real good way to catch an ERXAttachmentExceedsLengthException.

What I did was:

1. in your application class, override the "handleException" method and check 
if anException isinstanceof ERXAttachmentExceedsLengthException or any other 
kind of exception.

If the anException is a ERXAttachmentExceedsLengthException, try to go back to 
the page where you were coming from. In my example I stored the last page with 
the ERAttachmentUpload in my session, so I can restore it (and set an error 
message for the user):

public WOResponse handleException(Exception anException, WOContext context) {

if (anException instanceof ERXAttachmentExceedsLengthException) {
ERXComponent nextPage = ((Session) 
context.session()).lastPageBeforeAttachmentExceedsLengthException();

if (nextPage instanceof Main) {
((Main) 
nextPage).setErrorMessageFromException("ERROR: This attachment is too 
big. ...");
}
return nextPage.generateResponse();
} else {
OtherExceptionResponsePage nextPage = 
(OtherExceptionResponsePage)

pageWithName(de.i4innovation.app.components.OtherExceptionResponsePage.class);
nextPage.setTheException(anException);
return nextPage.generateResponse();
}
}


2. There is a Javascript/jQuery solution to check the file-name and file-size 
BEFORE you actually upload the file to your server.

It assumes your wo:ERAttachmentUpload has the id 'uploadButton'. The save 
button has the id 'saveButton' and an initially not displayed div has the id 
'uploadMessage'.

With jn("#uploadButton").change(function(evt) ... you bind a function to the 
Upload button that is fired during the onChange event -> that means before the 
file is actually uploaded.


It works like this:










/* extend js' string with an endsWith function */
function endsWith(str, suffix) {
return str.indexOf(suffix, str.length - suffix.length) !== -1;
}

/* define the max file size */
var maxFileSize = 20971520;

/* run jQuery in noConflict mode */
var jn = jQuery.noConflict();

/* attach this function to the file-upload-button's onChange event */
jn("#uploadButton").change(function(evt) {
if (window.File && window.FileReader && window.FileList && 
window.Blob) {
// Great success! All the File APIs are supported.
var files = evt.target.files; // FileList object
// files is a FileList of File objects. List some 
properties.
for (var i = 0, f; f = files[i]; i++) {
var msgDiv = 
document.getElementById('uploadMessage');
var msgButton = 
document.getElementById('saveButton');
if (f.size > maxFileSize) {
var fSize = f.size/100;
var msg = "ERROR: This attachment is 
too big.
Maximum file size is: 10MByte, actual file size: 
"+fSize.toFixed(2)+" MByte.
Please upload a smaller file!";
msgDiv.style.display = "block";
msgDiv.innerHTML = msg;
msgButton.style.display="none";
} else {
if (!endsWith(f.name.toLowerCase(), 
"zip")) {
var msg = "ERROR: This file 
is not a zip file.
Please choose a zip file.";
msgDiv.style.display = "block";
msgDiv.innerHTML = msg;
msgButton.style.display="none";
} else {
msgDiv.style.display = "none";
msgButton.className= "btn 
btn-success";
msgButton.style.display = 
"block";
}
}
}  // end for-loop
} else {
alert('CAVE: This browser doesn\'t support attachment 
size validation!');

document.getElementById('saveButton').style.display="block";
}
});



If you like I would send you the demo project I've developed. It's only 27kb, 
but I'm not sure to post it on the list here.

Re: How to pass confidential information with WORedirect.

[CHRISTOPH WICK | i4innovation GmbH, Bonn]

POST doesn't solve a "security" problem. It maybe obfuscates the parameters for 
a layman but it doesn't encrypt them. Anyway ...

WORedirect uses HTTP status code 302 which makes the browser using GET. What 
you need is HTTP status code 307.

So, write your own subclass of WOCompnentent with a setter method for the URL 
to redirect:

public class MyRedirectComponent extends ERXComponent {
private String url;
public MyRedirectComponent(WOContext context) {
super(context);
}
public void appendToResponse(WOResponse aResponse, WOContext aContext) {
aResponse.setHeader(this.url, "location");
aResponse.setStatus(307);
}
public void setUrl(String url) {
this.url = url;
}
}

The method that submits your form should look like this:

public WOActionResults submitAction() {
MyRedirectComponent nextPage = (MyRedirectComponent)

pageWithName(your.app.components.MyRedirectComponent.class);
nextPage.setUrl("http://YOUR_REDIRECT_URL";);
return nextPage;
}

See 
http://programmers.stackexchange.com/questions/99894/why-doesnt-http-have-post-redirect

Re: Help with EGWrapper / generated Excel file is always empty

[CHRISTOPH WICK | i4innovation GmbH, Bonn]

Hi Theodore,

thx for your hint. I did view the podcast, but it didn't help very much (mostly 
since I'm not using D2W).

Nevertheless, I found the culprit.

I had 2 more linebreaks after the closing  tag in my template. I 
removed them and now everything works perfect. It seems to be the same as with 
ERPDFGenerator. If you have linebreaks after the closing  
tag, it doesn't work either.

I get a download of "InfoMaterialAbo.xls" but the file contains only two 
linebreaks - no table, no excel.

Excel-framework is included, EGWrapper tag is recognized. Did I miss something? 
Is there any other configuration necessary?
HTML table is generated, if enabled="$false".

Any ideas how to debug this?

Re: Components binding with custom object

[CHRISTOPH WICK | i4innovation GmbH, Bonn]

To check the state of session.authenticatedUser replace the public property in 
your session (if you have one) by a pair of getter/setter methods.

Then you can set a breakpoint (or write a log) in these methods to inspect the 
state of your authenticatedUser.

For your problem with the session being accessed in components of your 
framework: You could implement a class called "FrameworkSession" in your 
framework that extends ERXSession (or WOSession) and then extend the Session 
class in your app from that FrameworkSession.

If you then put the getter/setter for authenticatedUser in the class 
"FrameworkSession", you could downcast your B's session() method to 
FrameworkSession and then access the authenticatedUser there like 
((FrameworkSession) session()).authenticatedUser()

It is technically possible, but maybe not a good idea, because you have to move 
all your Session's code to FrameworkSession. Remember: "Lasagne"-Code is the 
object oriented version of "Spaghetti"-code :-)

Re: Components binding with custom object

[CHRISTOPH WICK | i4innovation GmbH, Bonn]

Hi Ronald,

1. does your B.java contains a either a public property e.g.

public UserAccount userAccount;

or a getter/setter pair, e.g.

private UserAccount _userAccount;

public UserAccount userAccount() {
return this._userAccount;
}
public void setUserAccount(UserAccount newUserAccount) {
this._userAccount = newUserAccount;
}

Note, that (cum grano salis) for each binding you define in the Component API 
there must be a public property or a getter/setter pair with exactly the same 
name in the java code.

2. are you sure that the property "authenticatedUser" in your session is not 
null when the component is rendered?

BTW: since ((Session) session()).authenticatedUser should be accessible in 
every component of your app - also the subcomponents - you may use it directly 
in your subcomponent instead of passing it via a binding. Jm2¢.

Re: importing a csv file into a wonder application

[CHRISTOPH WICK | i4innovation GmbH, Bonn]

Old NeXT-style would be using the method "componentsSeparatedByString" of 
NSArray.

So, this is how I make it (assuming '\n' is used for linebreak and '\t' for 
cell) and Apache Commons IO for file reading:

String contentOfFile = FileUtils.readFileToString("/my/file.csv", "UTF-8");
NSArray lines = NSArray.componentsSeparatedByString(contentOfFile, 
"\n");
for (String line : lines) {
NSArray cells = NSArray.componentsSeparatedByString(line, "\t");
for (String cell : cells) {
NSLog.out.appendln("Got cell" + cell);
}

Re: Display group example?

[CHRISTOPH WICK | i4innovation GmbH, Bonn]

Hi Alberto,

on
https://wiki.wocommunity.org/display/WEB/Your+First+Stateful+Project

you find an example that uses a display group.

AFAICS it doesn't show to full beauty of display groups but it should give you 
first hints how to use it.

WebObjectsBuilder once had this wonderful feature of just dragging an EO from 
EOModeller and getting a master-detail component almost automatically. But 
WebObjectsBuilder is gone and that feature never made it into WOLips (AFAIK). 
Maybe D2W is what you're looking for today.

Re: Curl with javamonitor direct actions

[CHRISTOPH WICK | i4innovation GmbH, Bonn]

Hi Jeff,

did you use the JavaMonitor that comes with Wonder 
(https://jenkins.wocommunity.org/job/Wonder/lastSuccessfulBuild/artifact/Root/Roots/JavaMonitor.tar.gz)
 or the one that comes from Apple with WO.

AFAIK only the Wonder version can handle the DAs. The Apple version cannot.

(to to discriminate between: the Apple version looks like Aqua in MacOS X 10.0 
from 2002, the Wonder version is graphically a littler more up2date and has a 
"Log Out"-tab.)

Re: ERAttachmentUpload with AjaxSubmit

[CHRISTOPH WICK | i4innovation GmbH, Bonn]

Hi Samuel,

thx a lot. You made my day. 

Sometimes the naming of Wonder components is confusing to my limited cognitive 
faculty. Since e.g. AjaxSubmitButton can be used instead of ERXSubmitButton or 
AjaxFileUpload instead of WOFileUpload I was looking for something called 
AjaxAttachmentUpload instead of ERAttachmentUpload. So I simply should have dug 
just a little deeper into every Wonder class that starts with ERAttachment.

Re: WOLips Copy & Paste issue on Yosemite

[CHRISTOPH WICK | i4innovation GmbH, Bonn]

Hi Daniele,

I remember that I experienced the very same problem some time ago (not on 
Yosemite but on Mavericks). 

I didn't found a reliable solution. :-( But I stopped investigating since the 
problem disappeared after a complete reboot of my laptop.

So - at least - you are not alone ...

ERAttachmentUpload with AjaxSubmit

[CHRISTOPH WICK | i4innovation GmbH, Bonn]

Hi there,

I try to use an ERAttachmentUpload within a form that's submitted by an 
AjaxSubmitButton - but it doesn't work.

The action method bound to the AjaxSubmitButton is called BEFORE the setter 
method of the fileupload is called. (Should be the other way around??). 
Therefore no attachment is uploaded.

If I replace the AjaxSubmit with a plain old WOSubmit, everything works fine.

Any hints? Is it impossible at all to use file uploads within Ajax submitted 
forms?

Thanks, Christoph

Expired GPG-Key for Debian or Ubuntu deployment installation

[CHRISTOPH WICK | i4innovation GmbH, Bonn]

Hi List,

there is this wonderful description on "Installing a deployment environment on 
Debian or Ubuntu" on 
https://wiki.wocommunity.org/display/documentation/Installing+a+deployment+environment+on+Debian+or+Ubuntu

First, it tells you to import the GPG-Key with

> $ wget -qO- http://packages.wocommunity.org/ubuntu/signature.gpg | sudo 
> apt-key add -

Unfortunately the key you get has expired on January, 13. 2015.

Can someone with appropriate access rights (Bastian?) create a new GPG key?

Thanks a lot,

Re: WOWODC 2015

[CHRISTOPH WICK | i4innovation GmbH, Bonn]

Hi all,

are there any wishes for a presentation topic?

Maybe some of the participants want to learn something on WO/Wonder that is 
otherwise pretty old or easy for others. 

So if we knew what's of interest, maybe someone could easily make a 
presentation about it. 

C.U.CW

P.S.: My personal interest would be to learn more about ERRest. I have a 
somehow good understanding about how to get it working technically. But I'd 
like to know more about the pragmatics of building applications or APIs with 
it. It feels like having understood how EOF works but not how to build a 
session based applications.

Re: Help! Have array of EOs. Need convert to CSV (selected key paths)

[CHRISTOPH WICK | i4innovation GmbH, Bonn]

Hi Robert,

Maybe this helps:

1. create a ordinary WOComponent, e.g. MyCSVComponent.wo 

In the HTML part, you don't write HTML (skip the whole " ... 
" stuff), but the CSV content you need:


"", "" ...


2. in MyCSVComponent.java you override the method "appendToResponse" like this:

public class MyCSVComponent extends ERXComponent {

public String fileName;
public NSArray myList;
public MyObject item;

// override appendToResponse to let the browser make a download, 
// instead of displaying the result in a brwoser window
public void appendToResponse(WOResponse response, WOContext context) {
// set the mimetype to csv
response.setHeader("text/comma-separated-values", 
"content-type");
// tell the browser to download the file instead of showing it 
in a window
response.setHeader("attachment; filename=\""+fileName+"\"", 
"Content-Disposition");

// create the response
super.appendToResponse(response, context);
}
}

where "fileName" is the name of the file you will give the download.

In your master page, create a link like this:

download CSV

and in the Java-Code of your master page

public WOActionResults downloadCSVAction() {
MyCSVComponent nextPage = (MyCSVComponent) 
pageWithName(MyCSVComponent.class);
nextPage.myList = ... // set the list to an NSArray of whatever 
you need
nextPage.fileName = ... // set the fileName to whatever you need
return nextPage;
}


Does this answer your question?

ERXTimestampUtilities.differenceByDay doesn't work correctly

[CHRISTOPH WICK | i4innovation GmbH, Bonn]

Hello there,

is it possible, that ERXTimestampUtilities.differenceByDay doesn't work 
correctly?

I have the following piece of code: 

> NSTimestamp dec312015 = new NSTimestamp(2015, 12, 31, 0, 0, 0, null);
> NSTimestamp jan012016 = new NSTimestamp(2016,  1,  1, 0, 0, 0, null);
>   
> NSLog.out.appendln("ERX 2015/2016: 
> "+ERXTimestampUtilities.differenceByDay(dec312015, jan012016));
> 
> NSTimestamp dec312016 = new NSTimestamp(2016, 12, 31, 0, 0, 0, null);
> NSTimestamp jan012017 = new NSTimestamp(2017,  1,  1, 0, 0, 0, null);
> 
> NSLog.out.appendln("ERX 2016/2017: 
> "+ERXTimestampUtilities.differenceByDay(dec312016, jan012017));

The output is:

ERX 2015/2016: 1
ERX 2016/2017: 0

This is obviously wrong because it should return 1 in both cases.

I think the culprit is 
ERXTimestampUtilities.offsetForDateInCommonEra(NSTimestamp t, int mode), 
because ERXTimestampUtilities.differenceByDay simply calculates 

> offsetForDateInCommonEra(t2, mode) - offsetForDateInCommonEra(t1, mode);


with mode=Calendar.DAY_OF_YEAR.

If you pass mode=Calendar.DAY_OF_YEAR and a timestamp to 
ERXTimestampUtilities.offsetForDateInCommonEra, it calculates

> case Calendar.DAY_OF_YEAR:
> return calendar.get(Calendar.YEAR) * 365 + 
> calendar.get(Calendar.DAY_OF_YEAR);


So it simply takes the number of years times 365. But 365 is not the right 
value for leap years.

Can someone confirm that ERXTimestampUtilities.differenceByDay is buggy? Or am 
I completely wrong?

Re: WO Crashs while trying to set a boolean property used in a wo:if

[Christoph Wick]

Hi Chuck, 

thanks for the information.

Does it make sense to have a non-stateless non-synchronizing component?

My rule-of-thumb has always been stateless+non-synchronizing or 
non-stateless-synchronizing. But it seems to be a 2x2 matrix.

WO Crashs while trying to set a boolean property used in a wo:if

[CHRISTOPH WICK | i4innovation GmbH, Bonn]

I have a strange problem:

in a component I use a wo:if:


 ...


Its 'condition' property is bound to a method that calculates true or false.
There is no corresponding setter method like 
'setProviderCanChangeStatusToSUBMITTED(boolean b)' because it's not necessary 
to store such a value.

Nevertheless my app crashes complaining that there is no corresponding setter 
method (Stacktrace below).

For testing I implemented an empty setter method:

  public void setProviderCanChangeStatusToSUBMITTED(boolean b) {}

and then everything works fine.

Any ideas why WO is trying to call this setter method?


Stacktrace is:

Re: little off topic, need help understand a recursive call

[CHRISTOPH WICK | i4innovation GmbH, Bonn]

Hi Theodore,

AFAICS there is nothing wrong with your "isNumber" method (besides that 
Integer.parseInt(String s) and catching the NumberFormatException is much 
shorter).

I have no proof at hand, but I remember that each recursive call has a loop 
equivalent and vice versa.

So assume you have a something like

 public void printNumber(int start, int stop) {
   for (int i = start; i<=stop; i++) {
 System.out.println(i);
   }
 }

You can make a recursive version like

 public void printNumbersRecursive(int start, int stop) {
   if (start <= stop) {
 System.out.println(start);
 printNumbersRecursive(start+1, stop);
   }
 }

In this case I would aways prefer the loop-version. It somehow feels more 
natural to me.

But there are problems where recursion can be very handy. E.g. if you have 
non-linear structures like trees.

Assume the following class:

public class MyNode {

 private String name;
 private NSMutableArray children = new NSMutableArray();

 public MyNode(String name) {
   this.name = name;
 }
 public void addToChildren(MyNode child) {
   children.addObject(child);
 }
}

and you build the following structure with it

public static void main(String[] args) {

   MyNode root = new MyNode("root");

   MyNode child1 = new MyNode("child1");
   root.addToChildren(child1);
   MyNode child2 = new MyNode("child2");
   root.addToChildren(child2);

   MyNode child11 = new MyNode("child11");
   child1.addToChildren(child11);
   MyNode child12 = new MyNode("child12");
   child1.addToChildren(child12);
}

If you want to do something on all nodes (also called 'traversion'), e.g. write 
a debug info to the console, I would code this like

 public void debug() {
   System.out.println("node: "+name);
   System.out.println("children: [");
   for (MyNode child : children) {
 // recursion
 child.debug();
   }
   System.out.println("]");
 }

A call of root.debug() in the main method would produce

node: root
children: [
node: child1
children: [
node: child11
children: [
]
node: child12
children: [
]
]
node: child2
children: [
]
]

A non-recursive version of the debug method would be much more complicated.

ERRestRouteExample not working

[CHRISTOPH WICK | i4innovation GmbH, Bonn]

Hi list,

I try to get the "Client" example of the ERREstRouteExample application 
running. But it doesn't work.

Lines 29/30 of "Client.java" are

> ClientCompany c = client.objectWithPath("Company/1.json");
> System.out.println("Client.main: single company = " + c);

But if you let the example run, the output is:

> Client.main: single company = null

so "client.objectWithPath("Company/1.json")" ALWAYS returns null (although the 
URL works, if you call it manually)

After digging into the code, I found the class "ClientCompanyRestDelegate.java" 
with its method

> public Object objectOfEntityWithID(EOClassDescription entity, Object id, 
> ERXRestContext context) {
>   return null;
> }


that is called. So, obviously I get "null".

My questions are now:
- has anyone make this example running?
- or is this whole example broken?

Thx for your help.

is there a webobjects/wonder way to *consume* a REST service in a wonder app?

All the RESt examples on the wiki show how to produce a REST service using 
Wonder. But I can't find a good way to consume them.

(Sidenote: yes, I know, that you can/should/whatever consume them on the client

Re: ERCaptcha shows all black image

[CHRISTOPH WICK | i4innovation GmbH, Bonn]

Hi Klaus,

I remember that I once had trouble with ERCaptcha on a Linux deployment 
machine. I think I was because ERCaptcha somehow uses AWT internally and the 
Java process tried to connect to a Windowserver (which wasn't running).

The solution was to start the app with '-Djava.awt.headless=true' in Monitor or 
setting the property in the Application constructor with 
'System.setProperty("java.awt.headless", "true");'

Anyway, this shouldn't happen during development on OS X, since AWT is there 
for your Java process.

C.U.CW

P.S.: I suppose you set the captcha's "validated" binding to a boolean?

Re: Static resources in CSS file while using Linux as dev platform

[Christoph Wick]

Hi Ralf, hi list,

thanks for your answer.

Of course, I'm using wonder.

But it doesn't work the way you suggest.

If I replace

> body {
> background: 
> url("/WebObjects/OurApp.woa/Contents/WebServerResources/gfx/background.jpg") 
> repeat;
> }

with 

> body {
> background: url("gfx/background.jpg") repeat;
> }

the background image is not displayed. CSS's urls need absolute URLs.

The stylesheet itself is a static resource and is linked with

Static resources in CSS file while using Linux as dev platform

[CHRISTOPH WICK | i4innovation GmbH, Bonn]

Hi List,

I have a question because a colleague of mine wants to test Linux as 
development platform.

Background:
---
I the css file of OurApp.woa we refer to background images like e.g.

#a-div {
background: 
url("/WebObjects/OurApp.woa/Contents/WebServerResources/gfx/background.jpg");
}

To make this working during development on the Mac, I put a softlink from

/MYPATH_TO_ECLIPSE/OUR_APP_PROJECT/build/OurApp.woa --> 
/Libary/WebServer/Documents/WebObjects/OurApp.woa

This works on the Mac, since the WO-build-in development server somehow scans 
/Library/WebServer/Documents/ (the default document root for Apache on Mac) 
during startup and delivers the resources to the browser.

Problem:

Since there is no /Library/WebServer/Documents/ on Linux (default is 
/var/www/html - at least on Ubuntu), this doesn't work on Linux

Since my colleague doesn't want to create a folder 
/Library/WebServer/Documents/ (let's call this decision sort of "religious" but 
nevertheless :-) I was looking for the place where that 
"/Library/WebServer/Documents/"  information came from.

The only place I found, was 
/PATH_TO_WO_FRAMEWORKS/JavaWebObjects.framework/Resources/WebServerConfig.plist.
 Inside this plist there is an entry 'DocumentRoot = 
"/Library/WebServer/Documents";'

Now, my colleague could modify the plist entry and everything works fine, but 
...

Question:
-
Is there any other way to tell the WebObjects development environment to look 
for the document root than patching the WebServerConfig.plist inside the 
JavaWebObjects.framework folder?

Side notes:
---
I tried to override the documentRoot() method of my Application class to return 
the correct path, but it's never called during startup. At least while in  
development mode.

I also tried to set the property "application.documentRoot" - same effect. 
Doesn't work.

Thanks for your help, C.U.CW

Re: Any plans to build libapache2-mod-wo for Ubuntu 14.04 LTS

[CHRISTOPH WICK | i4innovation GmbH, Bonn]

Hi Bastian,

thx (again ;-) for your explanation. Maybe you can update the docs in the wiki.

Another thing: 

Line 4 of apache's config file for the webobjects module 
(/etc/apache2/mods-available/webobjects.conf) is:

> Alias /WebObjects /var/lib/webobjects/htdocs/WebObjects

Unfortunately this doesn't work out of the box. At least, it does not on Ubuntu 
14.04 LTS. According to my (limited) understanding of apache configuration, it 
should be:

> 
> Alias /WebObjects /var/lib/webobjects/htdocs/WebObjects
> 
> Options FollowSymlinks
> AllowOverride None
> Require all granted
> 
>   

Could you fix this as well?

Re: Any plans to build libapache2-mod-wo for Ubuntu 14.04 LTS

[CHRISTOPH WICK | i4innovation GmbH, Bonn]

Hi Bastian,

it works like a charm now - thx a lot. Checked on a clean fresh installation.

One more question: the WOMonitor that comes with that installation LOOKS as it 
is the old one from Apple (big fat Aqua-Tabs), not like the one from Wonder 
(see http://wiki.wocommunity.org/display/documentation/Deploying+on+Linux).

On the other hand, it contains some Wonder-Frameworks (if you take a look into 
/var/lib/webobjects/Library/WebObjects/Applications/JavaMonitor.woa/Contents/Frameworks).

So my question: is this intended? Are there two separat version of Wonder's 
WOMonitor. Or is the one in you package simply outdated? (Can't remember 
anymore when Wonder's WOMonitor got the new design. But it must haven been some 
years ago). If so, can it be updated also?

Thx again for the installer. Great to work with this community.

Kind of virus on this list?

[CHRISTOPH WICK | i4innovation GmbH, Bonn]

Hi List,

each time I send a mail "to" someone and "cc" to this list 
(), I get 

1. a mail from  pretending to be a system 
message telling me, that the original message could not be delivered.

2. a spam mail from , subject "Thank you for your email"

Does anyone get the same messages? Is this a kind of "virus" in the list or is 
there something wrong with my own mailserver (I pray, it's not :-)

Hi Bastian,

thanks for updating the Ubuntu/Debian installer.

Unfortunately, it doesn't work for me.

I installed a fresh and clean Ubuntu 14 LTS and followed the instructions on 

http://wiki.wocommunity.org/display/documentation/Installing+a+deployment+environment+on+Debian+or+Ubuntu

with

DIST=ubuntu
SUITE=trusty

I get the following error:

Re: Retaining order of values in a url

[CHRISTOPH WICK | i4innovation GmbH, Bonn]

Hi John,

If you read the documentation of WORequest's formValueKeys method, it says:

"The returned array is not sorted in any particular order, and is not 
necessarily sorted in the same order on successive invocations of this method."

(http://wocommunity.org/documents/javadoc/WebObjects/5.4.2/com/webobjects/appserver/WORequest.html#formValueKeys())

So I assume your workaround will not work always (even if it does sometimes), 
since you assume, that request.formValueKeys() gives you the right order.

If you really care about the order of the key-value-pairs in the URI, I think 
you have to parse the query string manually. 

Take a look  at NSArray's wonderful method "componentsSeparatedByString(String 
string, String separator)" and apply it to your WORequest's method 
"queryString()" with separator "&". then a second time on each key-value-pair 
with separator "=" and then you should have the key at "objectAtIndex(1)" in 
the same order as within the queryString.

C.U.CW

P.S.: What's the reason you want to know the exact order? I haven't needed such 
a thing in many years of web development.

It's the gcc you get, when you install it with "sudo apt-get install gcc".

Re: Character Encoding of textfield

[CHRISTOPH WICK | i4innovation GmbH, Bonn]

Hi Jens, hi list,

I prefer to have such things in the code since they a) are absolutely essential 
and b) never change. Especially if you have a non-english app. 

I remember, we once corrupted the content of a large database, when an 
over-ambitious dev-op apprentice removed that property because he "thought" it 
was the default. :-(

Re: Character Encoding of textfield

[CHRISTOPH WICK | i4innovation GmbH, Bonn]

Hi Jens,

does your wo-form set 'enctype="multipart/form-data"' ? (AFAIK it is necessary, 
if you are using WOFileUpload)

If so, try to use the following in your Application's constructor:

public class Application extends ERXApplication {
...
public Application() {
...
WOMessage.setDefaultEncoding("UTF-8");
WOMessage.setDefaultURLEncoding("UTF-8");
ERXMessageEncoding.setDefaultEncoding("UTF8");
ERXMessageEncoding.setDefaultEncodingForAllLanguages("UTF8");
...
}
...
}

I also had the problem with umlauts and this helped me.

Re: Wonder documentation on jenkins.wocommunity.org broken?

Hi there,

First of all thanks to those who fixed it.

Yes, there is a wonder list. It was probably my fault to post this original 
question on this (WebObjects) list. Sorry for that.

But does it really make sense these days to distinguish between WO and Wonder? 
The community has become relatively small and I personally don't know nobody 
who is using pure WebObjects without Wonder. IMHO we should concentrate on as 
few resources as possible. And this Apple-provided list is still my first 
address.

So once again sorry, if I bothered someone.

Wonder documentation on jenkins.wocommunity.org broken?

[Christoph Wick]

Hi List,

is the Wonder documentation on 
http://jenkins.wocommunity.org/job/Wonder/javadoc broken?

It looks as if all the style information is missing.

ERXApplication.replaceApplicationPath doesn't work

[Christoph Wick]

Hi list,

in one of my applications, ERXApplication.replaceApplicationPath doesn't work.

As usual, I wrote into my Properties file:

er.extensions.ERXApplication.replaceApplicationPath.pattern=/cgi-bin/WebObjects/ProPilotsMgmtApp.woa
er.extensions.ERXApplication.replaceApplicationPath.replace=/ProPilotsManagementApp

The values are read, as the startup log shows:

>   ...
>   er.extensions.ERPrototypes.hasLocalization=false
>   
> er.extensions.ERXApplication.replaceApplicationPath.pattern=/cgi-bin/WebObjects/ProPilotsMgmtApp.woa
>   
> er.extensions.ERXApplication.replaceApplicationPath.replace=/ProPilotsManagementApp
>   er.extensions.ERXComponentActionRedirector.enabled=false
>   ...

But the WO-generated HTML contains always the 
"/cgi-bin/WebObjects/ProPilotsMgmtApp.woa".

Has anyone an idea what could make the replacements not working?

I have no glue where to look further ...

P.S.: Apache rewrite rules work.

Endless logs "WARN NSLog - ** DirectToWeb could not find user.d2wmodel file. One will be created if you try to save changes."

[Christoph Wick]

Hi List,

I get endless logs of 

"WARN  NSLog  - ** DirectToWeb could not find user.d2wmodel file.  One will be 
created if you try to save changes."

in Eclipse. I don't use DirectToWeb in this project. 

Does anyone know how to stop that?

Thx for any hint,

Hi Pascal,

I'd really like to help fixing this (and other things too). How can I get

Screencast about Localization from WOWODC09 missing

[Christoph Wick]

Hi List,

I'd liked to watch the Screencast about Localization from WOWODC09.

It is linked on http://wiki.wocommunity.org/display/WEB/Screencasts?src=search, 
but the linked file 
(http://www.wocommunity.org/podcasts/wowodc/west09/WOWODCW09-Localization.mov) 
does not exist.


Can anyone fix this? Pascal?
Or has anyone a local copy that I could use?

P.S.: The one on iTunes says "This video requires Quicktime which is not

Re: WOLips gives WO Template Problems (keypaths) even if not real problems!

Aehm, yes, sorry. I meant inline bindings.

AFAIK there's nothing like the // VALID for inline bindings. 
But I'd love to learn that there is something ...

Re: WOLips gives WO Template Problems (keypaths) even if not real problems!

Hi Chuck,

is there something like the "// VALID" marker if you are using WOOngl?

"// VALID" is working only if you are using WOD, isn't it?

Re: Silly error message using wo:popupButton in WOLips' component editor

[Christoph Wick]

Hello List.

Thx for all the help - it was something different and I think, I found the 
culprit:

For an IDontKnowWhyReason, the build.properties file of my project contained 
the following lines:

> component.inlineBindingPrefix=$
> component.inlineBindingSuffix=

I assume this came from changing the value in preferences dialog of Eclipse.

I removed the second line and the error messages disappeared.

Silly error message using wo:popupButton in WOLips' component editor

[Christoph Wick]

Hello List,

I get a silly error message in WOLips' component editor. The component content 
is

>  selection="$customerRoleSelection" displayString = 
> "$customerRoleDisplayString" noSelectionString = "$noSelectionString" />

seems ok so far.

But in the component editor I get a silly error message:

> 'item' must be bound when 'displayString' or 'value' is bound


'item' is bound, so what's going on here?

"Project->clean" in Eclipse didn't help.

Any ideas? Thanks.

Re: WebObjects-Projects?

[Christoph Wick]

Hello Jürgen,
hello all,

as long as I'm in the WO business (since 2001), I've never seen anybody using 
WO in big business. It has always been small to medium sized projects. I my 
case 10 to 100 kilo-Euros. "Once upon a time" there must have been big WO 
installations outside Apple - but that was in the pre-2000 era. 

Nevertheless, I'm still using WO as a business. I was mostly successful 
acquiring new WO projects when the client 
- had no inhouse IT department (as soon as there are already inhouse IT people, 
the chance to get WO used in new projects goes to zero),
- had no further requirements (such as using a certain technology or wants to 
use OpenSource),
- was only interested in "getting the job done". 

Thanks to WO/Wonder itself as well as the excellent WO community, I was always 
able to get my customers happy. In functionality, in budget and in time!

So, my personal strategy is to find a client with
a) a problem (that can be solved)
b) money (I had endless discussion with people having a problem and "wishing" 
it to get solved - but no business case at all)

You won't find such clients in "project marketplaces" or something alike. I 
find them - more or less - by accident. But nevertheless I find them.

Including Fonts into PDF using ERPDFGeneration

[Christoph Wick]

Hi List,

I try to include fonts into a PDF document using ERPDFGeneration. The 
documentation of ERPFDWrapper tells me that there is a binding called "fonts". 
The binding is described as "(optional) array of font filenames to include for 
PDF generation".

OK so far. But whatever I set the "fonts" bindings to, I get an 
ClassCastException that a String cannot be casted to NSArray. 
Stacktrace below.

I've looked into the code and I found line 120 in FlyingSaucerImpl.java:

NSArray fonts = (NSArray) 
configuration.objectForKey("fonts"); 

So, what's the correct syntax of the bindings value string to be converted into 
an NSArray of Strings? I've tried ['Font 1', 'Font2'] as well as {'Font 1', 
'Font2'}, but that all doesn't work.

Thx,
C.U.CW

Sending a message to other application instances

[Christoph Wick]

Hi there,

is there a webobjects way to send a message to other instances of my app on a 
server running WO monitor?

I have developed a GUI to manage some app preferences. The config is stored in 
an XML file on disk. On my production machine, I have multiple instances 
running. I want to let them know, if the user has modified the configuration. 

Thx,
C.U.CW

Is there a documentation about the possible keys for that? What kinds of keys

Re: @Override of EO?

[Christoph Wick]

Primary keys are not set normally (sort of ...). And you should not override 
setter methods of EOs!

The method of your choice may be overriding 
EOEnterpriseObject.awakeFromInsertion(EOEditingContext ec).

If your class is e.g. Poster (and you use EOGenerator), then use

public class Poster extends _Poster {

@Override
public void awakeFromInsertion(EOEditingContext ec) { 
super.awakeFromInsertion(ec); 
fireMyUnixProcess();
}

}

Re: NullPointerException while using ERPersistentSessionStorage

[Christoph Wick]

Dear Ramsey,

thx for your helpful suggestions. I followed them and many bugs disappeared. 

But at the end, there are still some showstoppers of type "The Fun™" - see 
stacktrace below.

It happens, if I'm trying to save something back into the DB. It seems that 
deserialization of the persistent session always fails, if the session has to 
deal with one of my PMSUsers objects. My model is basically

PMSUser.school() -> PMSSchool, PMSScholl.students() -> PMSUser

I don't thinks, that this is a model t complicated. But I'm not sure. I am 
afraid that fixing this is beyond my WO knowledge. But if there are any hints I 
would try to dig into that.

NullPointerException while using ERPersistentSessionStorage

[Christoph Wick]

Hi List,

I was trying to use ERPersistentSessionStorage (looks otherwise very promising, 
thx Ramsey).

I'm getting a silly NullPointerException (stacktrace below) in an application 
that was working perfectly before without using ERPersistantSessionStorage. I 
have no idea how to debug this to get more information.

The problem may come from storing an EO object called PMSUser in the session 
(basically a user object with name, login, passwd ... PMS=prefix for the 
project's classes). The code is:

public class Session extends ERXSession {

private PMSUser currentUser = null;

public PMSUser currentUser() {
return currentUser;
}

public void setCurrentUser(PMSUser currentUser) {
this.currentUser = currentUser;
}
...
}

The page where the error occurs is the one where the user can change his/her 
personal data using a form like 



...
 


but NOT AFTER saving, but directly before rendering the page with the form.

Any ideas? Thanks in advance,
C.U.CW

How to make entity properties unique?

[Christoph Wick]

Hello list,

is there an easy, WO-style way to ensure the uniqueness of entity properties?

SQL supports it (by making columns UNIQUE), but I didn't find anything in 
EOModeler as well as in ERXMigration.

There is ERXEOControlUtilities.validateUniquenessOf(...) but I think this 
doesn't use the database level (so I think it MAY fail in a multi instance 
deployment).

Thanks in advance.

Re: NSNumberFormatter

[Christoph Wick]

Hi Oliver,

use the "validateKey" mechanism (where "Key" is the name of property, e.g. 
myNumber)

public Object validateMyNumber(Object aValue) throws 
NSValidation.ValidationException {
// 1. cast aValue to int (or whatever you need
// 2. write check method, e.g. SOMETHINGWRONGWITH_aValue
// throw exception, if aValue is not what you want it to be
if (SOMETHINGWRONGWITH_aValue) {
throw new NSValidation.ValidationException(aValue+" is 
not allowed for property 'MyNumber');
}
}

This method will be called by WO automatically before the settermethod 
setMyNumber is called.

Or you overwrite "validateForSave" or "validateForUpdate" in your entity's 
class (which should be a subclass of EOCustomObject).


For more basic information see:

https://developer.apple.com/legacy/library/#documentation/WebObjects/Enterprise_Objects/BusinessLogic/BusinessLogic.html%23//apple_ref/doc/uid/TP30001011-CH204-DontLinkElementID_12

or the documentation of NSValidation 
http://wocommunity.org/documents/javadoc/WebObjects/5.4.2/com/webobjects/foundation/NSValidation.html

or the documentation of EOCustomObject
http://wocommunity.org/documents/javadoc/WebObjects/5.4.2/com/webobjects/eocontrol/EOCustomObject.html#validateForUpdate()

Hope, this helps ...

Re: javamonitor and wotaskd won't start after os x updates

[Christoph Wick]

Hi Greg,

can you start WOMonitor manually? Try to execute

/System/Library/WebObjects/JavaApplications/JavaMonitor.woa/JavaMonitor

(if you are using the original Apple WOMonitor, or the one from Wonder wherever 
you've installed it)

Does the log (defined in your LaunchDaemon's 
com.apple.webobjects.womonitor.plist) tells you anything?

ERXMigration not working in ERXAjaxApplication

[Christoph Wick]

Hi there,

I have a strange problem.

I had an ERXApplication that used ERXMigration. Everything was fine, my H2 
database schema was created on the fly.

Then I changed ERXApplication to ERXAjaxApplication and suddenly ERXMigration 
didn't work anymore.

I tried back and forth, but

ERXApplication  -> ERXMigration ok
ERXAjaxApplication  -> ERXMigration does not even start

Same EOModel, same Migration classes and same properties.

Can someone explain this? Is there a workaround? Thx,

How to handle ERXAttachmentExceedsLengthException in ERAttachmentUpload

the ERAttachmentUpload component throws an ERXAttachmentExceedsLengthException

How do I handle this exception? Can I catch it somewhere? At the moment it is 
caught in my Application's handleException(Exception anException, WOContext 
context) method, but that's too general.

Thanks for your help,

Re: Internet Explorer can't download excel sheet as attachment

[Christoph Wick]

Hi,

I can't remember exactly how it worked, but I can remember that I once had a 
similar problem with IE and downloading attachments. 

I solved it by writing a direct action for the download. 

It was because IE  uses two HTTP requests to get the attachment and does not 
like it when the URL changes (or was it the HTTP headers - sorry this may sound 
silly, but I'm on vacation right now and do not have access to my dev machine). 
Just give it a try.

Re: Deployment question: WO puts IP address in URL when using HTTPS

[Christoph Wick]

Hi John, thanks for your hint. 

Unfortunately the apache config is not the problem here, but it is WebObjects 
(or Wonder) that puts the IP-Addresses into the URL if you are using HTTPS.

What I need are relativ URLs (without IPs), because the app shall be accessible 
from both, before and behind the firewall.

Deployment question: WO puts IP address in URL when using HTTPS

[Christoph Wick]

Hi there,

one of my clients runs a WO application on a Linux box behind a firewall. The 
internal IP of the box is e.g. 192.168.1.100. The external IP (through the 
firewall) is e.g. 1.2.3.4.

Running the app using HTTP is no problem, since all Link-URLs are built as URIs 
only, e.g. 

But if we use HTTPS, the Link-URLs are built as full URLs using the internal IP 
address, e.g. https://192.168.1.100/cgi-bin/WebObjects/App.woa/...";>

Links like this are - obviously - not accessable through the firewall.
Any ideas? A magic switch in Wonder, I was missing ...

Thx,
C.U.CW

Re: Cannot link against WO 542 api doc

[Christoph Wick]

It's a javadoc.xml ant file, generated by Eclipse. I call it from the command 
line "ant -f javadoc.xml".

It looks pretty simple:






 


   
http://developer.apple.com/documentation/WebObjects/Reference/WO53_Reference/"/>
 

http://www.junit.org/junit/javadoc/4.5"/>

http://java.sun.com/javase/6/docs/api/"/>

Cannot link against WO 542 api doc

[Christoph Wick]

Hi there,

I try to link the javadoc for my projects against the javadocs of WebObjects 
5.4.2.

Therefore I put

http://developer.apple.com/legacy/mac/library/documentation/InternetWeb/Reference/WO542Reference/"/>

into my javadoc.xml ant file. Unfortunately I get an error message:

  [javadoc] javadoc: warning - Error fetching URL: 
http://developer.apple.com/legacy/mac/library/documentation/InternetWeb/Reference/WO542Reference/package-list

OK, the file "package-list" is missing.
I downloaded the api docs and inserted a manually created "package-list" file 
into the api docs.

Doesn't work either :-(

Funny to note, that it works with the WO 5.3 api doc using "http://developer.apple.com/documentation/WebObjects/Reference/WO53_Reference/"/>"

Any ideas?

Re: recognising dead instances

[Christoph Wick]

We normally implement a direct action - let's call it "checkSystemStatus" - 
that performs a fetch to ensure the database operates the way we want it. If 
this fetch succeeds, we just return the string "OK". Otherwise we return the 
exception message and the stack trace.

On a second system, we run a bunch of crontab controlled shell scripts (every 
10 min) that perform a "wget" on that direct action, e.g. 
"http://YOURSERVER/cgi-bin/WebObjects/YOURAPP.woa/YOURINSTANCE/wa/checkSystemStatus";.
 If that wget returns something different from "OK", we send an email with the 
result.

Very simple, but it works for us.

Re: WOApplicationWizard fails to create new project

[Christoph Wick]

The allInOne version that is currently downloadable from

Eclipse says Version 3.3.2 Build id: M20071205-0800
WOLips core is 3.3.5224

Meanwhile, I got it running under the account, I installed it (local
