Business Process Choreographer Explorer
The following FAQ refer to Business Process Choreographer Explorer.
FAQ: How do I troubleshoot exceptions that I receive when I use the process template structure or the process state view in Business Process Choreographer Explorer?
Answer: Business Process Choreographer Explorer uses REST APIs for connection to the BPE and HTM containers. Verify that your REST API configurations are correct. For more information, see REST API exceptions when using Business Process Choreographer Explorer, and also the Related Information section in the link to verify that the REST API settings are correct.
FAQ: Why do I receive an error message in Process Instance View in Business Process Choreographer Explorer, stating that the user is unauthenticated, even after I have configured the REST API settings correctly?
Answer: To check settings, complete the following steps:
- Open the administrative console and click Applications > Enterprise Applications.
- In the right panel, click BPEContainer_scope, where scope is either nodeName_serverName or clusterName, depending on whether you configured Business Process Choreographer on a server or on a cluster.
- In the right panel, under Detail Properties, select Security role to user/group mapping.
- Ensure that the mapping for the J2EE BPEAPIUser role is set to All authenticated.
- Repeat these steps for the TaskAPIUser role of the TaskContainer_name application.
- Save your changes, and then restart the server or cluster on which you configured Business Process Choreographer.
