Error while trying to communicate with DRM API Adapter at http://localhost:5240/oracle/drm/adapter?wsdl

Here is a fix for the above issue.. it took me 4 days to figure out what was happening....

1. Check if the url and port for the api adapter is correct. to test it just copy/paste the url in browser.

2. Check if you setup the api adapter in DRM configuration console. 

3. Check if  you have created an external user in DRM and a user with the same name in shared services and a user with the same name and password in weblogic.
