hi,
i had been trying to deploy a simple hello bean but kept on getting deployment exception so i thought may be there is something wrong with my binaries or deployment descriptors, so i tried using the code,build files and deployment descriptors of ex04_1 from jboss workbook4.
I am still getting the same errors

s/jboss4.0.2/jboss-4.0.2/server/default/deploy/titan.jar
