All the jar files are in place alongwith the classpath, and the web.xml and
.class files look fine. I'm using Tomcat version 4.0.4, JUnit version 3.4,
Cactus version 1.4b1 and J2SDK1.4.0 on a machine running Windows 2000,. I
would greatly appreciate it if anyone could offer suggestions as to what is
going wrong. I searched through the archives and found Micah Williams had
reported the same problem some time back. I couldn't find the solution in
the response threads however.
Thanks,
rohit
