JSDK 2.1 development --> JSDK 2.2 in Tomcat

["Dunkle, Ed" <Ed...@ameriserve.com>]

Is it critical to compile code against the same JSDK version that is in
Tomcat?

I am developing in an environment that uses JSDK 2.1 but then deploy to
Tomcat 3.1 which includes JSDK 2.2.  My JSPs don't work under Tomcat
although they work fine in development.

I guess the other difference is that I am presently using JSP .9 spec in
developemnt.  That won't fly in Tomcat, right?  I have to use JSP 1.1 spec?


Using WebSphere in development there is nice support for JSP syntax checking
and debugging.  How do you track down JSP problems under Tomcat?

I see the work directory has jsp java and class files, but the one I'm
having trouble with as a zero length so I don't know where to find the
syntax error.

Also, I don't see where System.out or System.err messages go.  Maybe that's
because I have Tomcat running as a service so there is no console window...

Thanks,
Ed

The differences in the servlet API between 2.1 and 2.2 were almost all
additions, so it's pretty much upward compatible.

That's right -- the tag syntax under JSP 1.0/1.1 is very much different from the
syntax of JSP 0.91 or 0.92.  These pages are not going to be compatible at all.
