[JBoss jBPM] - problem accessing jbpm-console (jbpm 3.2.1 GA) on weblogic s
by naseem.k
Hi,
I am using jBPM version 3.2.1 GA. I tried to deploy the jbpm-console.war on weblogic server 8.1.
I managed to deploy it on weblogic. I resolved all the issues which are coming on weblogic like problem of antlr related to hibernate 3.1 and weblogic 8.1. Secondly I faced problem in query parser class that I changed to ASTQueryTranslatorFactory from ClassicQueryTransactionFactory as I am using hibernate verion 3.1.
There is no error on the console at the time of deployment. weblogic console shows successful deployment message.
Now when I tried to access the URL: http://localhost:7001/jbpm-console/search/tasks.html, I got exception on the browser.

Please help. What could be the cause of this exception?
Warm Regards,

[JBoss Seam] - Re: No active transaction?
by toni
What is the best approach then for a task which might last for 1-6 hours, which is the case with mine. I have increased the transaction timeout already to 2h, but yesterday the task stopped after 2h, without raiging any exceptions.
I found the following message in the logs:

>From my own application log messages I can tell, that the task is not being completed. Is there a way not to run this task within a transaction?
I already thought of marking the method with TransactionAttributeType.REQUIRES_NEW, but I'm not sure if this would solve the problem, as there still would be the outer transaction, which probably would time out after 2 h nevertheless.
What's the best approach?
