Fail to get my MDB authenticated

[uhed]

I have a MDB that shall invoke a secure local (internal) session bean.

Despite that the MDB is logged in using JAAS, I got "Authentication exception, principal=null" when I try to create a server object in the MDB

The MDB is set up with <run-as><role-name>xxx...

I've worked further and found a solution myself:

In the test client I used JAAS login successfully with

Start argument: -Djava.security.auth.login.config=security-context.config

Content of security-context.config:
------------------------------------------------------------------
LtKtrlClient {
org.jboss.security.ClientLoginModule required debug=true;
};

other {
org.jboss.security.ClientLoginModule required debug=true;
};
------------------------------------------------------------------

Java code:
------------------------------------------------------------------
UsernamePasswordHandler handler = new UsernamePasswordHandler("Username", "password".toCharArray());
String contextName = "MyContext";
LoginContext lc = new LoginContext(contextName, handler);
lc.login();
------------------------------------------------------------------

I copied this to my MDB but it did'nt work there...

After some research I found out that the test client uses Sun's implementation of javax.security.auth.login.Configuration
(com.sun.security.auth.login.ConfigFile) and the MDB use JBoss' implementation (org.jboss.security.auth.login.XMLLoginConfigImpl)

So, how to fix that?

I did simply add a line
Configuration.setConfiguration(new com.sun.security.auth.login.ConfigFile());
before
LoginContext lc = new LoginContext(contextName, handler);

I don't know why but now it works and me and my MBoss (= manager/boss ;-) are happy.

Do any one have comments?
