[JBoss-user] principal=null problem

[Khaled Aboudan]

Hello,   I wrote LoginModules for JAAS Authentication. Calling secured EJBs from a local client works fine. However, calling the same EJBs from a Tomcat causes a security exception stating that the principal is null.   I have seen this discussed in many different threads. But I still have not seen any final verdict about the subject. Some people suggested to use 'Tomcat Style login Interceptor' ...is this the way to go? Could someone explain why this happens?   Thanks in advance for your help.   Regards, Khaled
