UrlRewrite Rule works on tomcat 4.1.34 but fails on tomcat 5.0.28

[ying lam]

I would like to do the following:
rewrite from
http://localhost:8080/testApp?arg1=abc&arg2=def
to
http://localhost:8080/testApp/index.jsp?arg1=abc&arg=def

So i have the following rule in my urlrewrite.xml (under WEB-INF
directory)
<rule>
<from>^\?(deviceCode=.*)$</from>
<to type="redirect">%{context-path}/index.jsp?$1</to>
</rule>

Everything works in tomcat 4.1.34. But when I deploy the same webapp
in tomcat 5.0.28, url rewrite does not work.
When I enter 'http://localhost:8080/testApp?arg1=abc&arg2=def', it goes
to
http://localhost:8080/testApp/?arg1=abc&arg2=def

Can you please tell me how can I achieve the same thing in Tomcat
5.0.28?

Thank you.
