Authentication exception, principal=null

[Sivakumar Nachimuthu]

Hi everybody,

I've just created session bean webservice. It works fine till I switch on the security domain for my whole application. Although I didn't specify any security constraint for this particular ejb (no "security role" or "permission" in descriptors), invoking webservice from client ends with exception:

java.lang.SecurityException: Authentication exception, principal=null

Anybody has an idea, how to disable this authentication? Thanks in advance for any advise/url.
