I was also able to replicate Tim's stack trace on a windows machine... the relevant part is here..
at org.apache.jasper.compiler.DefaultErrorHandler.javacError(DefaultErrorHandler.java:130)
at org.apache.jasper.compiler.ErrorDispatcher.javacError(ErrorDispatcher.java:293)

It looks like in Tim's case, the compilation called at JspServletWrapper:190 triggers an error, that my system is swallowing. My system apparently makes it to JspServletWrapper:195, where it then seems to be looking for the compiled jsp class file, which it's not finding -- only then does my system show the stack trace. The question, I guess, is why is my system swallowing the javac DefaultErrorHandler? I guess I'll dig into the code.
Thanks,

I replicated this experiment exactly in my environment. Tomcat 4.1.24, Linux, JSDK 1.4.1_01. Is it a Linux thing?
Here's my stack trace in localhost:

By the way, I really appreciate your time in helping with this.

You should get something somewhere. For example ... With 4.1.24 (win2k, jdk1.3, but 1.4 is the same result), I have a file called foo.jsp (at /) with the contents: <% more cowbell %>
My error screen is attached. In the logs (localhost_log.2003-06-17.txt) I get: 2003-06-17 16:34:06 StandardWrapperValve[jsp]: Servlet.service() for servlet jsp threw exception org.apache.jasper.JasperException: Unable to compile class for JSP

Okay. I did a clean install of tomcat. I placed a compilation
--in one of the example JSPs. I am now seeing this in the logs:
* catalina.out: start/stop messages * localhost_examples: a stack trace saying that there was a JasperException: unable to compile class for JSP * localhost_log: messages about servlet loading.
What I don't see is a message saying something useful about the compilation error -- like "Compile failed on line 10, statement expected" or some such. Are those messages just not generated?
