Session in bean

Question

I have a bean. At the end all variables are set to "". But anyway I need to insert it into a session before, but it seams that I can�t use sessions in bean.
// Clear the form
user = "";
password = "";
rpassword = "";
session.setAttribute("icq", iicq);
iicq = "";Andreas

Answer 1

Or how would you add session attributes to the bean, if thats possible I do not need to use a servlet.

}THat would be much better. But how can I set the attributes.
