New jsp error

[Dave Wingate]

.... well, it's new to me.
I'm trying to bring a old .war application onto a new version and installation of tomcat (4.1). All of my jsp pages worked fine on the old installation ( I think; this is something I inherited).
When I port my jsp's to v 4.1 I get this compilation error message:
org.apache.jasper.JasperException: Unable to compile class for JSP
An error occurred at line: -1 in the jsp file: null
Generated servlet error:

etc.
Has anyone seen this before? I'm stumped as to what the error message means.

[Bear Bibeault]

Hmmm, not the most informative error message I've seen. Does this happen on all the JSPs or just one specific page?

[Dave Wingate]

I didn't think the message was very helpful either.
It happens on all of my jsps.

[Dave Wingate]

I also noticed that I get this error message when I try to view the examples jsps that are shipped with tomcat (like examples/jsp/dates/date.jsp). Does this mean that my installation of tomcat is totally hosed. Do I need to reinstall tomcat? Or could this be a configuration thing I dont know about?

[Bear Bibeault]

The examples should work right "out of the box" -- I'd suggest reinstallig Tomcat from scratch.
