My add reward page gives me a null pointer exception when it's on the cs3 server, but it doesn't in eclipse. I'm not sure why. My other pages work fine.

I've already tried doing a touch on the web.xml file and it didn't help, so I reuploaded the web.xml file, but that didn't help either.

Make sure web.xml is under the WEB-INF folder and not the root folder

I've checked and it's in the right place.

i would suggest re testing you code in eclipse again then removing all files from server and upload all classes along with web.xml file again....

Do you think eclipse is just being more tolerant of my mistake somewhere?

I can't get it working, so I'll just upload it the way it is. Thanks a lot for the help though.

I ran into a similar problem where my files would work on Eclipse, but not on CS3.  It's annoying, lol.

A common cause for this is hard-coding project path in URL. Note that your project may be called "hw1" in Eclipse, but on the server it's "cs320stu##". This problem usually causes 404 error, not null pointer though.

Null pointer exception should be easy to debug. Just read the error message carefully.

And yes, Eclipse is indeed more tolerant of errors than CS3.

I see. Were you able to fix it?
