exception on IsCallerInRole()

[hub1]

When I call isCallerInRole() I always get an exception.
I can successfully login using the ldapLoginModule but cannot call isCallerInRole().

I think I checked all the configuration files but cannot find anything (I am JBOSS novice).

Could anybody please give me a hint how I can fix this problem? What files to I have to touch, what to change?

Thank you
Hubert

Below is the exception that I get:

> 17:12:30,405 ERROR [STDERR] java.lang.IllegalStateException:

java:384)

I think I found the issue while reading through other posts.

I missed the <security-domain> entry in jboss.xml.
<security-domain>java:/jaas/SecurityRealm</security-domain>

P.S. Why is it so that I first have to post a question until I find the solution? I hate that. (Grmbl)
