Hi
When it is possible to access pakage level variables in the same package by other classes, then why do servlets communicate via query strings, session variables, hidden fields etc.
Why don't we make a class containing required variables, give it package level accessibility and set & use their values in servlets where-ever required?
Regards

Keep in mind that the main problem with servlets is managing user data so it doesn't get mixed up with other "simultaneous" users. The very elegant servlet API uses sessions for this. It is indeed a good idea to create a class to hold user specific variables. This can be shared between servlets by the session mechanism or whatever you like.
