Hi All,
Thanks for all the help, but the true solution I found was to replace the
tools.jar in tomcat5 with the tools.jar file from jdk1.6. Now I'm able to
get Struts2 up and running.
And they have a thread in sun's website related to this:
http://forum.java.sun.com/thread.jspa?threadID=5121172
thanks,
Jack

Ok, I have did all the steps below, and still can't fix this version problem
with Java.
1) Delete the "Catalina" folder under tomcat5/work/
2) Restart tomcat
3) Make sure javac and java are both 1.6 from the command line, and in the
tomcat configuration, the jvm path is:
C:\Program Files\Java\jdk1.6.0_01\jre\bin\server\jvm.dll
4) Go to http://localhost:8080/struts2-blank-2.0.6/
And get this error:
============================================================================
javax.servlet.ServletException: Unable to compile class for JSP
Generated servlet error:
C:\Tomcat5\work\Catalina\localhost\struts2-blank-2.0.6\org\apache\jsp\exampl
e\HelloWorld_jsp.java:7: cannot access java.lang.Object
Generated servlet error:
bad class file: C:\Program
Files\Java\jdk1.6.0_01\jre\lib\rt.jar(java/lang/Object.class)
class file has wrong version 49.0, should be 48.0
============================================================================
Version 48.0 is Java 1.4, version 49.0 is Java 1.5, but I only have version
Java 1.6(Version 50.0) on my computer right now.
Another question I have raised is that I downloaded and installed Java SDK,
do I need to download Java EE separately?
Thanks.

?! I hate to ask, but are you sure? If the compilation
is happening with one version and the execution with
another something seems horribly wrong.
You say you're using 1.6, but the trace below is using
1.5.
d.
Clean out your work directory so the JSPs are
re-compiled.

However, I encounter a new problem, when I go to

the following error.
I read compile each java src files and restart
tomcat again, still give me

That problem is definitely a jvm version issue.
Run:
java -showversion
to see what version you have in the path and make
sure it is 1.5 (1.6 should
be fine also)

Download a more recent JVM for Tomcat to use.
Looks like struts needs
1.5+...
