I am doing this :


and at line 12 it says : Null pointer access: The variable instanceId can only be null at this location

I want to give the value of instance id as input from jsp page :


I dont know what to do in servlet. Should i declare instanceId outside the method? I tried doing this :

and this in servlet :


it still gives null as ouput. What am i missing?

I wasn't using session so it was not taking some parameters to the next jsp page, once i used session for those, it worked fine.
Thanks
