JSP: org.apache.jasper.JasperException: Unable to compile class

[Tim Meals]

I'm have some trouble getting JBoss 3.2.1 with Tomcat 4.1.24 to compile
its generated JSP files. Looking in the server instance's work
directory shows the Java source being generated correctly from the JSP
file, but it fails to compile with the following stack track dumped to
the browser:

org.apache.jasper.JasperException: Unable to compile class for JSP

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

Generated servlet error:

-----
JAVA_HOME is configured correctly and tools.jar is showing up on JBoss'
classpath. The user running the process is the same user creating the
directory structure, and this is running on Java 1.4 on an HP-uX 11 box.

Thanks for any insights.
