      I am trying to integrate jbpm5 with ldap.

       

      env: jbpm5.3 /jboss7/ sample application/apacheDS(ldap)

       

      I have tried few things but its not working properly.

       

      1) changed web.xml in jbpm-human-task-war.war in jboss7 deployments folder.

          modified user.group.callback.class value to LDAPUserGroupCallbackImpl from DefaultUserGroupCallbackImpl

             <init-param>

            <param-name>user.group.callback.class</param-name>

            <param-value>org.jbpm.task.service.LDAPUserGroupCallbackImpl</param-value>

            </init-param>

      2) updated jbpm.usergroup.callback.properties with requried properties

          for e.g. ldap.user.ctx, ldap.role.ctx,ldap.user.roles.ctx, etc and kept in the war file, updated jbpm.usergroup.callback.properties the same in

          jbpm-human-task-core-5.3.0.Final.jar also in the lib of the above mentioned war, originally that file was empty.

       

      3) During the running ProcessTest.java sample i am getting the following error

       

      0    28/08 14:19:37,871[main] ERROR workitem.wsht.GenericHTWorkItemHandler.executeWorkItem  - Tue Aug 28 14:19:37 GMT+05:30 2012: Error when creating task on task server for work item id 1.

        at java.lang.Thread.run(Thread.java:619)

      Process started ...

       

      Not sure what i need to do get rid of this error.

       

      My ldap is running on the default port.

       

      following error is coming in ldap as well.

       

      [14:19:37] ERROR [org.apache.directory.server.ldap.handlers.UnbindHandler] - failed to unbind session properly

      Can anybody point to a complete example on the integration.

            Found the answer myself.

             

            we should have a user as Administrator, who creates the task by deafult.

             

            So the complete process for the configuration of JBPM5 with LDAP

             

            1) changed web.xml in jbpm-human-task-war.war in jboss7 deployments folder.

            modified user.group.callback.class value to LDAPUserGroupCallbackImpl from DefaultUserGroupCallbackImpl

                   <init-param>

                  <param-name>user.group.callback.class</param-name>

                  <param-value>org.jbpm.task.service.LDAPUserGroupCallbackImpl</param-value>

                  </init-param>

            2) updated jbpm.usergroup.callback.properties with requried properties

                for e.g. ldap.user.ctx, ldap.role.ctx,ldap.user.roles.ctx, etc and kept in the war file, updated jbpm.usergroup.callback.properties the same in

                jbpm-human-task-core-5.3.0.Final.jar also in the lib of the above mentioned war, originally that file was empty.

            3) Create a user as Adminstrator in your LDAP server.

            4) All the users in the bpmn as the ActorID must be there in LDAP directory.

            5) Run your program in my case its just the sample program -> Evaluation.bpmn/ ProcessTest.java
