Hi,

I am new to JSP and was trying to pass an arraylist of strings from one jsp to another via an iframe. But for some reason i get null pointer exception. I am pretty certain i am doing something stupid... but am having a hard time figuring out what is wrong... I would really appreciate it if someone could guide me in this regard...

This is what i am trying to do:
JSP1: testAnnoDriver.jsp



JSP2: testAnno.jsp



I have made a folder under Webapps in tomcat home directory and am running testAnnoDriver.jsp.

Thanks
Naveen Ramanathan

Don't iframes make a new request to fill their contents? (I almost never use them, so I really don't know.)

They are in completely separate requests. If you want to share things across them you'll need to use the session.
