java.lang.IllegalAccessError: try to access class com.sun.xml.tree

[alec <al...@bigfoot.com>]

Dear struts-user,

I am encountering an error when I try to access the struts-example and
the struts-test applications. The error is as follows:
-------------
Error: 500
Location: /struts-test/bean-parameter.jsp
try to access class com.sun.xml.tree.ParentNode from class
org.apache.jasper.compiler.TagLibraryInfoImpl
-------------

This is my classpath:
-------------
CLASSPATH=.:/usr/java/jdk1.3/lib/dt.jar:/usr/java/jdk1.3/lib/tools.jar:/opt/jaxp/jaxp.jar:/opt/jaxp/parser.jar
-------------

and tomcat starts up with the following classpath
-------------
/opt/tomcat/bin/startup.sh
Using classpath:
.:/opt/tomcat/lib/ant.jar:/opt/tomcat/lib/jasper.jar:/opt/tomcat/lib/servlet.jar:/opt/tomcat/lib/test:/opt/tomcat/lib/webserver.jar:/opt/tomcat/lib/xml.jar:/usr/java/jdk1.3/lib/tools.jar:.:/usr/java/jdk1.3/lib/dt.jar:/usr/java/jdk1.3/lib/tools.jar:/opt/jaxp/jaxp.jar:/opt/jaxp/parser.jar  
-------------

I do not see anything untoward. Am I missing something in my
configuration? Any help or direction would be appreciated.

I also get the following stack trace from tomcat:-
-------------
Unhandled error! You might want to consider having an error page to
report such errors more gracefully
