Precompile of JSPs no longer works with Tomcat 4.1.24

[Rob Stoecklein]

I'm running Tomcat on a Debian Linux box and have an Ant build script that 
automatically recompiles JSP files to java (using jspc) and then from these 
java files to class files (using javac).

This worked great in Tomcat 4.1.18, but when I upgraded to 4.1.24, this no 
longer works.

The symptom: the files compile with no errors, class files are created, but 
then when a JSP page is accessed using a browser, the following exception 
is thrown:

java.lang.NoClassDefFoundError: org/apache/jsp/login_jsp (wrong name: 
login_jsp)
        at java.lang.ClassLoader.defineClass0(Native Method)

The login_jsp page is my page it's looking for.

When I allow Tomcat to compile the JSP "java" files, the pages work fine. 
So there is some problem using javac from my Ant script.

I went to the Tomcat documentation at 
http://jakarta.apache.org/tomcat/tomcat-4.1-doc/jasper-howto.html#Web%20Application%20Compilation
and made my script identical to that Ant compile script, and it still did 
not work.

Does anyone have any ideas here?

Thanks for your time,
Rob
