Re: True war deployment and WebServerResources
Hi Lachlan; I did a proper maven packaging 'goal' for war and it works fine. It's just not easy to develop like that. The app's jar I am building is ~3M so it would take too long to keep making that. cheers.

Re: Deployment with Embedded Frameworks and Duplicate libraries
Thanks for all the help. I am making progress. Also, I have to turn direct connect off to be able to do the refuse new sessions, so is there another way to figure out which app is hung so that it can be killed? Look at the stack trace, like below. Also look for growing numbers of worker threads. If you have more than 16, you probably have a problem. I have checked and this seems to be my last problem. Every once in a while I get an instance that spawns 256 worker threads. The statistics show that this does not even require a lot of transactions. I did a stack trace and there were a few funny looking things, but the one that stood out the most was the following appeared a lot: Thread t...@80131: (state = BLOCKED) - java.lang.Class.forName0(java.lang.String, boolean, java.lang.ClassLoader) @bci=0 (Interpreted frame) - java.lang.Class.forName(java.lang.String) @bci=5, line=164 (Interpreted frame) - com.webobjects.foundation._NSUtilities._searchForClassInPackages (java.lang.String, com.webobjects.foundation.NSArray, boolean, boolean) @bci=92, line=417 (Interpreted frame) - com.webobjects.foundation._NSUtilities._classWithPartialName (java.lang.String, boolean) @bci=154, line=375 (Interpreted frame) - com.webobjects.foundation._NSUtilities.classWithName (java.lang.String) @bci=26, line=334 (Interpreted frame) - com.webobjects.appserver._private.WOBundle.lookForClassInAllBundles (java.lang.String) @bci=5, line=92 (Interpreted frame) - com.webobjects.appserver ._private.WOActionRequestHandler._actionClassForName(java.lang.String) @bci=1, line=70 (Interpreted frame) - com.webobjects.appserver ._private.WOActionRequestHandler.getRequestActionClassAndNameForPath (com.webobjects.foundation.NSArray) @bci=114, line=389 (Interpreted frame) - com.webobjects.appserver._private.WOActionRequestHandler._handleRequest (com.webobjects.appserver.WORequest) @bci=88, line=226 (Interpreted frame) - com.webobjects.appserver._private.WOActionRequestHandler.handleRequest (com.webobjects.appserver.WORequest) @bci=79, line=161 (Interpreted frame) - er.extensions.appserver.ERXDirectActionRequestHandler.handleRequest (com.webobjects.appserver.WORequest) @bci=222, line=123 (Interpreted frame) - com.webobjects.appserver.WOApplication.dispatchRequest (com.webobjects.appserver.WORequest) @bci=32, line=1687 (Interpreted frame) - er.extensions.appserver.ERXApplication.dispatchRequestImmediately (com.webobjects.appserver.WORequest) @bci=74, line=1791 (Interpreted frame) - er.extensions.appserver.ERXApplication.dispatchRequest (com.webobjects.appserver.WORequest) @bci=13, line=1756 (Interpreted frame) - com.webobjects.appserver._private.WOWorkerThread.runOnce() @bci=473, line=144 (Interpreted frame) - com.webobjects.appserver._private.WOWorkerThread.run() @bci=129, line=226 (Interpreted frame) - java.lang.Thread.run() @bci=11, line=613 (Interpreted frame) So it appears that a lot of threads are getting locked up in Class.forName(). I want to print out some debug information to try to figure out which class is being instantiated, but I did not want to fill up the logs too much. I have already run out of disk space because of too much logging. So my question is, is there a call somewhere where I can find the number of worker threads or when the number of worker threads is increased to 32? That way I can turn on the logging when it really matters. Thanks, Frank ___ Do not post admin requests to the list. They will be ignored.

war deploy under tomcat and session length?
The deployed app doesn't seem to be honoring the normal session timeout values; they're very short now;-( I came across an old thread that mentioned it being in the web.xml, but I'm not connecting what I need to set inside the various properties to extend this value.

Every once in a while I get an instance that spawns 256 worker threads. First off, I'd avoid that. It would be a remarkable application that could handle more than 16 or so concurrent requests. Take a look here http://developer.apple.com/documentation/WebObjects/WOAppProperties/Articles/ApplicationProperties.html#/ /apple_ref/doc/uid/TP40005337-SW1 Specifically WOListenQueueSize and WOWorkerThreadCountMax (I don't see the latter one documented). The best way to set these is using JavaMonitor to configure the application. I'd try a listen queue size of 5 and a max worker thread count of 10 to start. Having lower numbers will make the app fail faster when it deadlocks and this can result in a better user experience. The statistics show that this does not even require a lot of transactions.

Re: My first Eclipse D2W [solved]
Hola t...@s!
indeed it was a versioning problem...
I was running Europa instead of Ganymede...
with the advise of my e-friend Daniel Mejia (mil gracias ;^), I
downloaded the latest version of WO from ADC, and of the all-in-
one.pkg linked in the community web page, installed them and now
everything runs smoothly...
Thanks all for your attention and comments,
and specially to those which dedicated those hours to develop the
tools...
Yours sincerely,
Dino

It is picking up the wrong session. Using WO 5.3? You really
want / need to use Wonder if you are doing D2W. Wonder will fix
this problem.
I am running the latest version of WO (I suppose)
Might want to check that.
My WebServiceAsistent reports being 5.4 (I suppose all my WO is too).

I did try both D2W type of project (one of them being Wonder's)
with the same result/error
A proper Wonder project should fix this.
strange...
If you really won't use Wonder (and you will regret it), add
this to you Application class:
protected Class _sessionClass() {
return your.package.here.Session.class;
}
Tried but did not worked...
You got the same error? A different error?
exactly same error... I will start from scratch to see what
happens...
Chuck
I think I did something wrong from the beginning ... didn't I?
D2W is supposed to work from the box just with a model and a
running database, right?
Does Wonder's D2W needs something else?
Are there some versions issues I am not seeing?
Please, gimme some light on how to start using D2W with in the
Eclipse+WOlips+... environment!
Gracias!
Dino
And change your.package.here to the package your Session class
is in.
