Tried one more change to solve this issue,but still same exception- I tried updating persistence.xml file in "jbpm-human-task-5.0-SNAPSHOT.jar" file
under jbpm-human-task\src\main\resources\META-INF folder for Oracle related url,dialect,driver etc. under jbpm-gwt-console-server.war deployed in jboss.So basically I modified following things for Oracle DB configuration:-
1. Modified hibernate.cfg.xml,persistence.xml and testDS1-ds under (C:\Anand\jbpm5\jbpm-installer\db) folder path
2. Also I modified persistence.xml of jbpm-human-task-5.0-SNAPSHOT.jar file under "bpm-gwt-console-server.war" file deployed in jboss as mentioned above.
But I get same issue as mentioned in my last post related to "Could not synchronize database state with session
org.hibernate.exception.SQLGrammarException: Could not execute JDBC batch update".
Let me know if you get chance to fix this.
Thanks,
Anand
