[jboss-user] [JBoss jBPM] - problem accessing jbpm-console (jbpm 3.2.1 GA) on weblogic s

[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?
