Problem with Struts in IBM VisualAge 3.5.2

[Marco Spadoni <m....@pisa.iol.it>]

I'm trying to install and run Struts in IBM VisualAge 3.5 Patch 2 according
to the instructions
found in the paper from Kyle Brown ("Apache Struts and VisualAge for Java,
Part2: Using
Struts in VAJ 3.5.2 and 3.5.3").
Before to install the EmployeelistForApache.zip contents I was able to start
the Apache Tomcat
Test Environment and successfully run the default example applications.
After the installation and the configuration of the
EmployeelistForApache.zip contents, when I try
to start Apache Tomcat, I have the following messages (below) on VAJ
consolle, ending with the listed
exception stack frame.
Anyone that can give me an hint?
TIA,
