I think this problem is related to the JAXP parser being used. In the
ch21/WEB-INF/lib directory you need /either/:

* Copies of the jaxp.jar and crimson.jar files found in your
  $CATALINA_HOME/server/lib directory. These are slightly modified from
  the ones you can download from java.sun.com, to avoid this problem.

* The latest download from newparticles.com uses xerces.jar from Xerces
1.2.3
  instead.

Make sure you don't have any other copies of the JAXP parser files in the
$CATALINA_HOME/lib or $CATALINA_HOME%/common/lib directories. There's more
on
using XML parsers with Tomcat 4.0 in the release notes, in the
$CATALINA_HOME/src directory.

Subject: [pro_jsp] Re: Chapter 21 Struts Framework - example install
problem w/ Tomcat 4.0b7


I have now downloaded the "Wrox Example Source Code - wrox-struts-tomcat-
4.0-b6-08-07-2001.jar" from www.NewParticles.com.  I was sure this would 
correct my sealing violation problem, but it has not.  I opened up this 
jar file and recompiled the project using Ant 1.3(see results further 
down).  I copied all the created project files into .....webapps/ch21.  I 
still get the same sealing violation that I recieved previously when 
trying to access any jsp file in this project.  I have been experimenting 
with my path variable, but to with no luck.  I would appreciate any 
advice.  My project relies heavily on using the Struts Framework and this 
example would be a great place for me to get started if I can get it to 
work. Here are my path settings for Windows2000Advanced Server.
