Subject Re: 404 Error when accessing pre-compiled JSPs
Date Wed, 02 Jun 2004 23:13:36 GMT
Ah ha!

As it turns out, the </web-app> end tag in my web.xml
file got chopped off during the merge of web.xml
fragments.  I put this back on and everything seems to
work... except one thing:

We have some JSP files that get autogenerated by a
development tool we're using.  Most of these JSPs
compile fine, but there are a number that end up as
zero length .java files after compiling them with
jspc.  Is there any reason why jspc might create 
empty .java files for what look to be relatively
simple, but correct, .jsp files?
