Re: SOLVED: Immortal… ehm, frozen instances.

2013-04-03 Thread Chuck Hill

Sounds like it was timing out and throwing an exception that was improperly 
handled.  Seems odd that it would cause zombie sessions even with the 
try...finally in sleep() and terminate()

 the finally blocks didn't help.
 
 Something is calling session.terminate() directly though, happens when a 
 something bad happens in a direct action.
 
if (existingSession() != null)
sess().terminate();
 
 It's called only if we can't parse the parameters and should never happen. 
 I'll put some logging in those cases.

Re: WONettyAdaptor

2013-04-03 Thread Ramsey Gurley

In the testing I've done, I haven't noticed a great difference in performance 
between it and the default. But it's easier to do websockets with the 
WONettyAdaptor which might be reason enough to use it.

Re: [Excel] - Maximum column with EGSimpleTableCreator

2013-04-03 Thread Tobias Janz

Hi,

looks like nobody has used the ExcelGenerator-Framework with more than 255
Columns or a bit abstract with the xlsx-Format.
Maybe you could write an extension?
Also the version of the poi-jar is out of date, 3.9 is the latest stable
version (3.6 is 3 years old).
Looks like the SS Usermodel is a good idea.

It also produces stuff like

And then there's the plain ridiculous



I'm sure that stuff is fun to debug. All I need to know:

Re: custom page ??

2013-04-03 Thread Ramsey Gurley

Is it wo:link or wo:WOHyperlink? I guess you've tried both. 

If it's not the WOHyperLink thing, I'm not sure what the problem is. A 
hyperlink should work just fine. All the looks use them just fine. Try to cmd-2 
w that thing. I'll bet it works with a WOD binding. Inline bindings are The 
Devil after all.

But rather than customize an entire inspect page just to bring in a few 
hyperlinks, why not create a custom page controller and have methods like

public WOComponent generateReport(WOComponent sender)

on it? It sounds like you're trying to beat D2W into submission to do things 
the old way :-)

Bah, inline bindings are a great idea.

But only if you have them enabled, and the WOOgnl framework in your class path.

Re: custom page ??

2013-04-03 Thread Theodore Petrosky


that was me fat fingering it.

Error:   com.webobjects.appserver.parser.woml.WOMLTemplateParserException: 
ReportsPage: 4:5: Could not generate an element named: WOHyperlink
Reason:  Could not generate an element named: WOHyperlink

my goal is to bring in a simple component with hyperlinks on it. 

public class ReportsPage extends ERD2WInspectPageTemplate {

i am using these 4 rules for the component:

100 : pageConfiguration = 'ReportsPage' => entity = "User" [EntityAssignment]
100 : pageConfiguration = 'ReportsPage' => navigationState = "Reports" 
[Assignment]
100 : pageConfiguration = 'ReportsPage' => task = "inspect" [Assignment]
100 : pageConfiguration = 'ReportsPage' => templateNameForInspectPage = 
"ReportsPage" [Assignment]

if I have no WOHyperlink on the page, then it renders just fine.

here is the entire html:


Outlets Project Reports

Project 
Report



the action just starts the jasper reports process.

ideas?

custom page ??

2013-04-03 Thread Theodore Petrosky

I have a d2w app and I wanted to add a component to act as a report listing 
page.

I created a component called ReportsPage extending ERD2WInspectPageTemplate

my idea was to add a few hyperlinks that would create some wonderful jasper 
report documents.

my ReportsPage comes in fine but when I add a simple hyperlink:


Project Report


om.webobjects.appserver.parser.woml.WOMLTemplateParserException: ReportsPage: 
5:6: Could not generate an element named: WOHyperLink


so I assume that extending ERD2WInspectPageTemplate is my problem. 

Is there a better way to do this?

Re: SOLVED: Immortal… ehm, frozen instances.

2013-04-03 Thread Steve Peery

I strongly agree with the suggestion for a MySQL replication slave server. They 
are not that hard to set up and then you can dump a backup as often as you like 
with out effecting the main server and you always have an up to the minute copy 
incase something happens. I had a problem a couple of months ago and going to a 
backup up that was just a couple of hours old was a major loss.

 I thought it was fixed in 5.4.3, but I could be wrong.  In some past 
 version if that same URL can in in rapid succession, you would get 
 deadlocks like you are seeing.  The solution at the time was to not call 
 terminate directly and instead set the session timeout to a couple 
 seconds.  That allowed both requests to clear before terminating the 
 session.

Another longer term option is to have a MySQL replication slave server that 
performs backup snapshots as needed (hourly, daily, weekly).

 the finally blocks didn't help.
 
 Something is calling session.terminate() directly though, happens when a 
 something bad happens in a direct action.
 
if (existingSession() != null)
sess().terminate();
 
 It's called only if we can't parse the parameters and should never happen. 
 I'll put some logging in those cases.

Hi all,

I finally solved the problem… well, not really but I found out the reason. 
Turns out that the whole thing is on amazon boxes and the DB machine (MySQL) 
was being backed up every hour… The backup takes all the cpu (not the backup, 
the bzip2 of the backup) and locks up MySQL for 2 minutes, if an instance tries 
to access the db in those 2 minutes that instance won't be able to die 
properly. 
Solution? I removed the hourly backup which was useless and scheduled a nightly 
backup with a reniced bzip2. No issues from that day!

Thanks everybody for the help.

 I don't recall how ERTimeToKill works, but with those stuck threads you 
 are going to need to do
 
 Runtime.getRuntime().exit(1);
 
 and if THAT does not kill it, this should:
 
 Runtime.getRuntime().halt(1);

Re: ERRest and ERXKeyFilters advice

Hi Pascal

Thanks for that, the ERRest app uses a non-wonder framework that doesn't have 
ERXKeys for it so for now I am having to use strings.

 Hi 
 
 I am just starting my first ERRest app and playing with ERXKeyFilters.
 
 I have an OrganisationController using a filter and I remove unwanted 
 attributes from the rest response with:
 
 ERXKeyFilter filter = ERXKeyFilter.filterWithAttributes();
 filter.exclude("dateTimeStamp","autoNotify","notifyMethod","webSitePassword","website");
 
 This works great, however if I then have a TransactionController and a 
 Transaction object that has a to-1 Organisation relationship how best do I 
 also remove the unwanted Organisation attributes from the rest response? 
 At the moment I have the below:
 
 ERXKeyFilter filter = ERXKeyFilter.filterWithAttributes();
 filter.include("organisation").includeAttributes();
 filter.exclude("organisation.dateTimeStamp","organisation.autoNotify","organisation.notifyMethod","organisation.webSitePassword","organisation.website");
 
 
 but I can't help thinking there is a better way to ensure consistency 
 about what attributes are contained in the response for various EOs when 
 they form parts of responses that contain relationship objects.  Is there 
 a better way of achieving this?
 
 Thanks

Avoid using strings like this, if you rename your relationship, you will not 
see that you have a string to change. Either use 

  include(ERXKey key, ERXKeyFilter existingFilter) 

or :

  include(MyEntity.ORGANISATION_KEY, organisationFilter())

Re: ERRest and ERXKeyFilters advice

2013-04-03 Thread Giles Palmer

Hi

Thanks for that.  

I was actually trying to see if there was a way to ensure that eo's on their 
own or as part of a relationship get returned in the same form by having 
standard filters for each type of eo.

include(String keyName, ERXKeyFilter existingFilter)  is exactly what I was 
looking for.

So for my transaction filter with its to 1 organisation I can do:

ERXKeyFilter filter = ERXKeyFilter.filterWithAttributes();
filter.include("organisation", organisationFilter());

Where organisationFilter() is a filter determining how organisations should be 
filtered.

Thanks

Giles

If you are running snow leopard, pressing the 6 and 4 during startup should

 OK.  So I added this argument to the application's additional arguments in

 recompiling the JNI and I've changed the ARCHS variable in the build 
 properties to x86_64 but I'm still getting the error.  Does anyone who is 
 wise in the ways of MacOSX programming know where I've gone wrong?  I'm 
 using 10.5 and XCode 3.1
 
 Thanks,
 
 Johnny

 If my understanding is correct, Homebrew uses the installed system 
 libraries whenever possible. That's the reason to use, and to avoid, 
 Homebrew. Install an app with Homebrew, then update the system from 
 Lion to Mountain Lion and pray things still work.
 
 With macports, you install a full set of your dependencies in a 
 separate /opt/
