Hi Maciej,
Thanks for ur response. I checked all config files and i was not able to find where i made mistake. I have attached the LDAP screenshot ,server.log, jbpm.usergroup.callback.properties file for reference.
I think this is the cause of the complete problem. The following line is the error trace from server.log.
" Error when creating task on task server for work item id 52. Error reported by task server: There are no known Business Administrators, task cannot be created according to WS-HT specification: org.jbpm.task.service.CannotAddTaskException: There are no known Business Administrators, task cannot be created according to WS-HT specification" .
Please check and give me a solution.
Thanks,
