---------------------------------------
dear my friends , I have been counter with the same problem for 2 days, after learning the
security constract of ejb3 on jboss4, I finally find a esay way to solve this problem .
add
props.setProperty(Context.SECURITY_PRINCIPAL, "myuserid");
to your client program ...
then in the bean class
ctx.getCallerPrincipal();
will return "myuserid" which the client program determined above.
my client program is like this ..
Properties props=new Properties();
props.setProperty(Context.INITIAL_CONTEXT_FACTORY,
"org.jboss.security.jndi.JndiLoginInitialContextFactory");
props.setProperty(Context.PROVIDER_URL, "localhost:1099");
props.setProperty(Context.SECURITY_PRINCIPAL, "myuserid");//here!!!!!!!!!!!
InitialContext ctx=new InitialContext(props);
saha ss=(saha)ctx.lookup("sahabean/remote");
ss.sayhi();
my bean class is like this ..
@Stateful
@Remote({saha.class})
public class sahabean implements saha {
@Resource SessionContext ctx;
public String sayhi() {
System.out.println(ctx.getCallerPrincipal());//no exceptions now..
return "success";
}
}
remote interface "saha" is like this ..
public interface saha {
public String sayhi();
}
after deployed sahabean on jboss-4.2.3.GA-jdk6 and run client program, you can see the
output "myuserid" on your jboss command console.
i am confident that this code can normally run on jboss5 too.
best regards ..

The bug is pretty easy to create.
Modify the CalculaterBean in the security example that is distributed with JBoss embedded
like this
import javax.annotation.Resource;
import java.security.Principal;
import javax.ejb.SessionContext;
..
public class CalculatorBean implements Calculator
{
@Resource SessionContext ctx;
@RolesAllowed({"student"})
public int subtract(int x, int y)
{
Principal caller = ctx.getCallerPrincipal(); //Nullpointer
return x - y;
}
The exception

Another user has reported that is is possible to get the principal from
org.jboss.security.SecurityAssociation.getPrincipal(), but not from the Session Context.
