EOFException
Please help me pinpoint the cause of this exception. Im using jbpm 5.2, guvnor 5.3 and designer 2.4. I deployed all of this in a remote server in tomcat 6. And my database is postgresql. Process instances are successfully created in jbpm console but i think human tasks are not created because of this. I also cannot see any process on the personal task list. What could be the problem? Please help me
