Thanks, your advise helped me solve the problem in 5 min. The code I was trying to call returns information about the user by searching a database for a row with an id number that is set in the session information and returning the data on that row.
I've now put the search method in a class external to both Servlets, so they can each call it (Never heard of a DAO before your message, so thats my starter attempt). The only problem is that each time it's called the method calling it has to get session information to pass to it. Its only a couple of repeated lines in each servlet so I can live with it but it's a little clumsy. Any suggestions? If not thanks again for the help.
