dynamic virtualhost w/jsp (jserv) issue

hey there - i'm hoping this is simple...
I'm having an issue with one line vs. another. The commented out
rewrite rule is the one that compiles my index.jsp just fine, using
Jserv. If i use the uncommented rewrite rule that I WANT to use below,
to get the subdomain that the user requested, the index.jsp displays
uncompiled, in simple html format.
As always - any and all help is greatly appreciated.

<VirtualHost 172.18.4.13:80>
ServerName ics3dv1ws1.hq.bradgroup
ServerAlias *.ics3dv1ws1.hq.bradgroup
VirtualDocumentRoot /devl/ics3/devl/webroot/oc4j/ct/web
DirectoryIndex index.jsp

RewriteEngine on
#RewriteRule ^/(.*\.jsp) http://172.18.4.13:7778/ct/$1 [P]
RewriteRule (.*)\.ics3dv1ws1\.hq\.bradgroup/ct/(.*\.jsp)
http://172.18.4.13:7778/ct/$2?subdomain=$1 [P]
</VirtualHost>

Incase anyone's curious, i found the solution.. Followed below is a
great way to set up your VirtualHost to accept subdomains dynamically,
and push the subomain that the user requested to the URL (in my case,
to take java actions depending on the subdomain). Also, i added the
referring URL (HTTP_REFERER) so i can take action on that as well, to
the forwarding url. the final page in this case will be
<a style='text-decoration: underline;' href="http://172.18.4.13:7778/ct/index.jsp?subdomain=xxx&refer=xxx" target="_blank">http://172.18.4.13:7778/ct/index.jsp?subdomain=xxx&refer=xxx</a>

<VirtualHost 172.18.4.13:80>
ServerName ics3dv1ws1.hq.bradgroup
ServerAlias *.ics3dv1ws1.hq.bradgroup
VirtualDocumentRoot /devl/ics3/devl/webroot/oc4j/ct/web
DirectoryIndex index.jsp

RewriteEngine on
RewriteCond %{HTTP_HOST} ^(.+)\.ics3dv1ws1\.hq\.bradgroup$
RewriteRule ^/(.*\.jsp)
<a style='text-decoration: underline;' href="http://172.18.4.13:7778/ct/$1?subdomain=%1&refer=" target="_blank">http://172.18.4.13:7778/ct/$1?subdomain=%1&refer=</a>{HTTP_REFERER} [P]
</VirtualHost>
