Problem with JAAS example in WLS6.0sp1

Question

Hi,
I tried to run the SampleClient from the JAAS example in WLS6.0sp1 and got an
exception
when a valid username/password combination is entered. Has anyone experienced
that in WLS6.0sp1?
Thanx
Ralf

Weblogic comes with its own implementation of JAAS, unfortunately
conflicting with Sun's. Contact customer support, they will tell you the
exact differences and incompatibilities. Or reverse engineer the two
versions, you'll find quite a few differences (apart from the BEA version
not implementing JAAS authorization, which is documented).

I am happy someone came up with this problem. I also bent backwardssolving
this problem
in my application.
I figured out that as soon as I remove the standard jaas.jar from my
classpath , I can run the example successfully. Weblogic.jar does contain
necessary jaas library , so don't need to include jaas.jar.
I am not sure, but I get the feeling that there is a jaas library conflict
here. May be weblogic
guys are the best to put some light on this issue.

I found out, that the example runs with the JDK delivered by BEA,
but not with a JDK I downloaded from SUN.
Wheras with the first the provided way to set the user defined
configuration class with the system property'weblogic.security.jaas.Configuration'
works, this is not possible with another JDK. According to the
JAAS standard, this class could only be defined in the properties
file 'java.security' of the Java runtime.
How is BEA doing this?
Thanx
