How to create/get user & role in Weblogic 9.2
programmatically?

Hi,

I am new to Weblogic 9.
I need to create a web service to manage user/role in WebLogic 9.

Searching thru the web and found some classes like:
AtnSecurityMgmtHelper, AtnProviderDescription etc

Are those the correct classes to create/retrieve user & role?

If so, what jar file contains those classes and where is the jar
file?

Thanks in advance,
