Apache configuration with proxy and location

Question

I want to map these domains to these ports. How can I do it?

http://test1.example.com/phpmyadmin/    example.com:80/phpmyadmin/
http://test1.example.com/app1/          example.com:8080/app1/
http://test1.example.com/app2/          example.com:8090/app2/

http://webmin.example.com/              example.com:10000/

This is what i did. Problem is phpmyadmin is not working it is forwarded to glassfish.

webmin is working because it is a seperate domain.

How can I map phpmyadmin to thesame domain? http://test1.example.com/phpmyadmin/

Thanks
