Implementing login functionality in EJB

Question

I'd like to know other peoples views on how to implement logins in a container indepenant way.
Also how to pass client side info such as ip address around.
I'm thinking of a swing desktop client here.
One idea I had was when a client logs in, create a stateful session bean that stores their user id and ip address.
I've never used stateful session beans before, is this a good idea?

Answer 1

hang on, if I made my session facade statefull, and the first method you called was login...
all the other methods already have boilerplate code to wrap exceptions, not really a big deal to add checkIsLoggedIn();
public otherBusinessMethod1() throws ApplicationException, RemoteException{
  try{
    checkIsLoggedIn();
    do stuff...
  catch(Exception e){
    throw wrapException(e);
}This would work right?
I realise this has a scalability problem cause you're storing state on the server. I wonder how much of a problem.
I guess the other option is to pass the login info through each time
public businessMethod1(LoginInfo loginInfo){
  try{
    logIn(loginInfo);
    do stuff...
  catch(Exception e){
    throw wrapException(e);
}Or am I barking up the wrong tree altogether?
