I have the same problem with a different spin to it:

In the browser, I see
<<org.apache.jasper.JasperException: Unable to compile class for JSP

An error occurred at line: -1 in the jsp file: null

I solved it by re-installing tomcat in a directory that has no spaces in its
path. I don't know how I fell into this problem, because before, I ran tomcat
dozens of times successfully even with the space in the "..cat 4.1".

Suggestions:
For the exception case, have org.apache.jasper.compiler.Compiler.compile or
org.apache.tools.ant.taskdefs.Javac.compile with which arguments they call javac
and where they get them from!

One more strange observation:
- even though I installed with windows installer, the windows registry is
unchanged (still has the old paths with spaces e.g. in "JVM Option Number 0" or
"System.err File")
- it even has as "JVM library" a jdk1.3... that I deleted months ago
