When posting XML text, please use the "code" tag. You can do this by selecting the text and clicking the Code button that appears above the editor window. Also, use the Preview button to ensure the formatting before clicking Submit. As for your question, how are your entity beans packaged, and where is the persistence.xml file located? Be specific!

[JBoss jBPM] - Re: JbpmContext usage & best practices

by kukeltje

closing and opening the context is not expensive afaik... recreating a new JbpmConfiguration is!!! anonymous wrote : I thought that maybe I could have the context get closed by spring as soon as the entire transaction is finished.... Yes that is an option, but just make sure that one transaction does not span multiple requests (realy keeping it open). . That way your application would not scale. anonymous wrote : there are some cases where the context gets opened 5/6 times for a single request.. :( Why? I've never had that. Sure there is no 'design error' here?

[JBoss Messaging] - Re: Do you have example code embeding JBMBootstrapServer for

by clebert.suconic＠jboss.com

Or maybe what you're asking is different? It seems you want to use the MicroContainer to start your server?

by clebert.suconic＠jboss.com

Andy has written an example on trunk: http://anonsvn.jboss.org/repos/messaging/trunk/examples/messaging/src/org... I believe something similar existed at the time of Alpha and 'm not sure now but the example above would probably give you what you're asking.

[EJB/JBoss] - Class within axis.jar not found while using Stateful session

by RogerWBMD

JBoss Developer Studio 1.1.0 I built a 3rd party webservice client and tried to call it from my stateful session bean. I got the "java.lang.NoClassDefFoundError: org/apache/axis/client/Service" while publish the EAR. I don't why because the axis.jar has been added to the build path. I have no such problem when I change my stateful bean to POJO (EAR is published and the webservice call goes through without problem.) Btw, I got the same error while using a stateless bean.

[Performance Tuning] - Re: GC does not appear to be running

by PeterJ

GC has nothing whatsoever to do with the HTTP threads - those are all handle by JBoss Web. You never said which version of JBoss AS you are using, but the 4.2.x and 5.0 version use a JBoss Web based on Tomcat 6. If you look at the Tomcat 6 documentation you will notice that the various thread management settings (such as the unused thread timeout) are no longer documented. A perusal of the source code shows that those settings are still captured from server.xml, but the settings are never used. The end result is what you see - once HTTP threads have been allocated they seem to hang around forever.

[Performance Tuning] - GC does not appear to be running

by sra78

I am using JMeter to stress test my J2EE application that is running on JBoss. With regular usage the thread count will be at 50, with Stress test, the thread count go to 200-250. Even one day after the test, I still see the same thread count in JMX console. When I do listThreadCpuUtilization(), I can see that around 20 thread are using 0 CPU, around 100 of them are using 50-200 CPU cycles. I am not sure whether this is normal. Isn't GC Demon thread suppose to run and clean out these threads? If I restart JBoss, count goes back to 50. But when I run the stress test again to bring the thread count up, and wait couple of days, I still see these threads, active and taking some CPU cycles. Any suggestions? Thanks, Jackie.
