Re: Oracle JDeveloper 9i JSP Problem

Hi

Unfortunately, neither of the fixes suggested have been successful, though myself (and a couple of others in my team) think that the reason you've given sounds correct, and fits in with the results of some of the fixes we've already tried.

If there is anything else at all you can think of, I'd be glad to hear from you.

Thanks again for your help.
