The Node class has a potential deadlock condition in getLeavingTransitionsMap() if multiple users attempt to leave the same node at the same time. The leavingTransitionMap.put() method isn't thread safe so multiple threads can deadlock there. Other configuration methods are not thread safe but they don't matter because they are only called one time at startup.

[Persistence, JBoss/CMP, Hibernate, Database] - Re: beginner questions

by PeterJ

1) There is no way to tell from this configuration. Each app server provides its own persistent engine, with JBossAS using Hibernate. If you used this configuration on another app server you would get another persistence engine. 2) http://www.manning.com/bauer2/ View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4179864#4179864 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4179864

[JBossWS] - Re: Not getting instance of Service object from a WSDL file.

by PeterJ

Go back an read my previous reply, under item #1. You have to do your own searching for the correct set of JAR files. You will probably need to add about 12 JAR files to the classpath. If it were just one or two, I could tell you each time you get a CNFE which JAR you need to add, but doing this form a dozen JARs is too much work. One obvious shortcut is to include every JAR in the jboss_home/client directory in your client's classpath. (Though I vaguely recall that one or two if them are not there but in the server/xxx/lib directory. Anyway, if after adding all of the jboss_home/client jar files you still get a CNFE, post it and I will tell you which JAR it is in.)

[Installation, Configuration & DEPLOYMENT] - Re: apache2 + jboss4.2.3 ajp problem

by PeterJ

anonymous wrote : Question : Why sould we install Jboss native to install jboss as a service ? Actually, you do not have to "install" JBoss Native. You can, instead, copy just the service.bat and jbosssvc.exe files from jboss_native/bin to jboss_home/bin. Those are the only two files required to run JBossAS as a service.

[JBoss jBPM] - Re: Timers in jBPL

by juergen_lampe

This was THE hint - now it works as expected: <state name="warte 1"> | <timer name='reminder' | duedate='2 minutes' | transition='ex1' | cancel-event='node-left'> | <script> | System.out.println("Timer fired "+node); | </script> | </timer> | <transition to="Ende" name="ex1"></transition> | </state> | But the docu is misleading, saying: anonymous wrote : this attribute is only to be used in timers of tasks. it specifies the event on which the timer should be cancelled. by default, this is the task-end event, but it can be set to e.g. task-assign or task-start. ... Thanks a lot!

[JBoss Getting Started Documentation] - Re: Trailblazer fails to start

by PeterJ

4.2.x? Please be specific (4.2.x includes 4.2.3) The default security should grant you access. The only reasons I can think of that could cause this problem are: 1) Another MDB is using the same queue name, in which case perhaps only that MDB has read access to the queue. 2) A *-service.xml configuration file has that queue name declared, in which case the security settings in configuration file are being applied.

[JBoss Portal] - Re: Using Shared Libraries in Portlets.

by PeterJ

I assume that each portlet is being deployed in its own WAR file and that the library JARs required by the portlets are in their WEB-INF/lib directory. As you guesses, such JARs cannot be shared between WARs, as that would be against the spec. Here are a couple of solutions: 1) Places you WARs in an EAR and move the library JARs out of WEB-INF/lib and itn othe EAR (but leave the servlet/portlet JAR, if any, in WEB-INF/lib). 2) Move the library JARs out of WEB-INF/lib and place them into server/xxx/lib. I would go with option #1.
