UserGroupCallbackManager: Not returning callback

[houston4j]

Hello,

I'm unable to retrieve an instance of the UserGroupCallback using the UserGroupCallbackManager.

From my understanding this should work by setting the jbpm.usergroup.callback property:

System.setProperty("jbpm.usergroup.callback", "org.jbpm.task.identity.LDAPUserGroupCallbackImpl")

and calling:

UserGroupCallbackManager.getInstance().getCallback()

I get a null when the getCallback() method is executed. UserGroupCallbackManager.getInstance().existsCallback() returns false.

Is additional configuration needed to get the LDAPUserGroupCallbackImpl registered?

Hello,

At the creation of the knowledge session I use this code to register my usergroupcallback :

// By Setting the jbpm.usergroup.callback property with the call

        // back class full name, task service will use this to validate the

        // user/group exists and its permissions are ok.

              InputStream usergroupsin = KnowledgeSessionProducer.class.getResourceAsStream(  "/jbpm.usergroup.callback.properties" );

              if(usergroupsin != null) {

                        Properties callbackproperties = new Properties();

                        try {

                                  callbackproperties.load(usergroupsin);

                                  UserGroupCallbackManager.getInstance().setCallbackFromProperties(callbackproperties);

                                  log.debug("Task service registered usergroup callback ...");

                        } catch (Exception e) {

                                  log.debug("Task service unable to register usergroup callback ...");

                        }

              }

    if(UserGroupCallbackManager.getInstance().existsCallback()){

                        System.out.println("userGroupCallBack exists ! :)");

              }else{

                        System.out.println("userGroupCallBack don't exist ! :(");

              }

and I create a file name : jbpm.usergroup.callback.properties in src/main/resources

that contain this line :

jbpm.usergroup.callback=com.st.ams.task.management.AMSUserGroupCallbackImpl

This is the associated log :

17:06:45,137 DEBUG [com.st.ams.jbpm.knowledge.KnowledgeSessionProducer] (http--127.0.0.1-8080-3) init of KnowledgeSessionProducer ...

I hope it will help you.
