Description of problem:
I am creating this BZ to distinguish an issue with REST endpoints on WebLogic 12.1 from the one reported on WebLogic 12.2. The discussion about WebLogic 12.1 was started in bug 1306309 and some log files were attached there. But it might not be the same issue. REST calls on WebLogic 12.2 return "404 Not found" while on WebLogic 12.1 the result is "500 Internal Server Error" with an exception stack trace.

Version-Release number of selected component (if applicable):
6.3.0 DR2

Steps to Reproduce:
1. Try any REST call.
2. See the response and the server log.

Actual results:
javax.naming.NameNotFoundException: Unable to resolve 'com.sun.jersey.config.CDIExtension'. Resolved 'com.sun.jersey.config'; remaining name 'CDIExtension'

Expected results:
no exceptions

Additional info:
You can see the attached server log. After the server with Business Central was started, two REST calls were made.
