How to get the remote user from Ejb context in JBoss

I have a web application on Jboss 4.2.2 and i开发者_JAVA百科n its login sequence I have added a custom login module. In the getIdentity() of this module, for some reason I need to change it to be other than the username entered in the login form. On any jsp page, I can get this identity with no problem by request.getRemoteUser(). However, when I tried to retrieve this value in an EJB using ctx.getCallerPrincipal().getName() , it returns the username entered in the login form. So I would like to ask in what ways can I get the identity I expected.

Thanks in advance.

Should be a bug on jboss
