JR46428: REST API RETURNS 500 ERROR WHEN CLAIMING TASK

Download Version 8.0.1 Fix Pack 2 for the IBM Business Process Manager products

APAR status

• Closed as program error.

Error description

• When claiming a task using REST API via HTTP PUT request, the
  response
  returns with a 500 error. Although the request resulted in an
  error the
  task will still be claimed successfully. A similar error may be
  seen in
  the logs
  "org.apache.wink.common.internal.providers.entity.xml.AbstractJA
  XBProvid
  er
  getEntityToMarshal The ObjectFactory class for the
  com.ibm.bpm.rest.v1.data.task.TaskClaimResult class cannot be
  found or
  loaded.  Verify that a valid ObjectFactory class exists." A
  workaround
  is to use the REST UI Console to claim the task.

  ****************************************************************
  A HTTP 500 error may be returned when invoking the REST claim
  action API. Although the 500 error is seen, the state of the
  task will change from "STATE_READY" to "STATE_CLAIMED".
  Meaning the action actually succeeded, however, the response
  returned is not proper. The error occurs when "application/xml"
  is set in the request's "Accept" header.
  The following is a sample URL which may encounter the error
  when invoked:
  "http://localhost:9080/rest/bpm/wle/v1/task/208?action=claim"
  The following error may also be seen in the logs:
  "AbstractJAXBP E
  org.apache.wink.common.internal.providers.entity.xml.AbstractJAX
  BProvider getEntityToMarshal The ObjectFactory class for the
  com.ibm.bpm.rest.v1.data.task.TaskClaimResult class cannot be
  found or loaded.  Verify that a valid ObjectFactory class
  exists."
  

Problem conclusion

• Code changes have been made to properly return a successful
  return code when the task is being claimed via HTTP request.
  An interim fix will be available on v8.0.1.0. The fix will be
  integrated into the next fix pack.
