I think it qualifies as an EJB related question. I think what
you want to do it throw an application exception, which is
defined in the EJB spec. This exception does not extend
RuntimeException, so it may be caught by the client.
When our servlet attempts a login, and the password or username
is incorrect, our Session Bean throws an "InvalidLoginException",
which we wrote and which extends Exception. Since this is an
application exception, the container simply passes that exception
back to my servlet, and I am able to put up a specific web page
indicating what went wrong with a login form to retry the login.
Thus, send the message back as part of a specific application
exception defined just for invalid logins. Have your login bean
throw this exception when the login is invalid. Have your servlet
catch the exception, get the message, and process accordingly.
