I'm working on a proyect that uses some products of WSO2 like API Manager, ESB and BPS. The issue that I can't solve is, how can I access the Activiti services like identity/groups or identity/users through BPS?.
I downloaded, installed and ran BPS on my notebook. Enter to http://xxx.xxx.xxx.xxx:9445/carbon and load one of the samples files: CreditApprovalProcess.bar. After that I created some users and roles. I've tried with postman to hit these URLS from the docs:
- /repository/tasks --> http://...:9445/bpmn/repository/tasks
- /repository/deployments --> http://...:9445/bpmn/repository/deployments
- /repository/process-definitions --> http://...:9445/bpmn/repository/process-definitions
and they all work fine. However when I tried to hit these services:
- /identity/groups --> http://...:9445/bpmn/identity/groups
- /identity/users --> http://...:9445/bpmn/identity/users
defined here , I got this response {"errorMessage":"The server encountered an unexpected condition which prevented it from fulfilling the request","statusCode":500} . I've read that BPS 3.5.0 integrates Activiti engine and thus those services were available but clearly I'm doing something wrong. I'm new in WSO2 and I have to learn a lot yet so I appreciate any suggestion/idea. Thanks in advance.
Only Activiti BPMN engine is integrated into WSO2 BPS and it is using WSO2 Carbon Kernel based user management. Hence /identity/* Rest APIs, will not work in WSO2 BPS engine.
If you want to retrieve user/group information, use UserAdmin soap service. Following link will explain how you can do it in API Manager product, but instructions are similar for BPS as well.
