i have a little problems with my session. I use it to login on my site.
I have a login-form where th user must enter his name and password.
Than it is sent to the login.xsp file where a database-connection is
made. It check the user and his password if it ok a session is
create and there is the problem.
I get a NullPointerException, but after a simple reload in the Browser
it works well. It seems there is a problem with logicsheet.
When i create a simply session with:
xmlns:session="http://apache.org/xsp/session/2.0"; create-session="true"
and try to set some attributes it works, but if i attempt to create a session with my logicsheet and add some attributes it runs in a NullPointException, after a reload it works.
I must still say the cooky is create.
Can anybody help me with this problem.
bye Raphael
