I want to know how can i iterate this USER_GROUP_LIST in my read method and get the USR_GRP_ID field data from it.
A Prompt reply from your end will help me to resolve this issue

Guru Sir,
i tried to override the add() method of the framework in that i was able to iterate the field from the list. But now the i am facing there is that i am not able to send back the response to the external system in XML format. I am getting a blank response in my SOAP UI Tool while testing here is the code:

If you can help me to find out what went wrong here while sending the response back it can close my issue.
