Need some help on tomcat URL rewrite or mod_jk

Linux and Unix-Like Red Hat

I am trying to remove the context name from the url of my server.

Current URL - http://www.domainname.com/MyApp/

What I need to make is to make it avaialble at -

http://www.domainname.com/

I have already tried couple of things like below -

RewriteEngine On
RewriteCond %{REQUEST_URI} !^/(Context/.*)$
RewriteRule ^/(.*)$ /Context/$1 [P,L]
 
redirect permanent /MyApp/ http://domainname.com

Using JKMount -

JkMount /MyApp/* ajp13
JkMount /MyApp* ajp13

Deploy war file to ROOT of tomcat and make relevant chagnes in web and server.xml

All of these aren't working and I keep getting a intenal error.

Please put your suggestions if any.

Thanks,
Andy
