Reverse proxy to applications on a server by just domain names possible?

Question

Hi All
I am looking for a solution to set up a single server, that hosts four J2EE web applications running on a Glassfish application server with just only one IP address.
When a user wants to use an application, he/she can just type URL without specifing port and path, and the corresponding web application will be displayed accordingly as shown below
http://sub1.domain1.com -- > webapp1 at port 9100
https://sub2.domain1.com -- > webapp2 at port 9200
http://sub1.domain2.com -- > webapp3 at port 9300
https://sub2.domain2.com -- > webapp4 at port 9400
I am wandering whether I could use reverse proxy of Sun Java System Web Server 7 to route the traffic from the domain names to their own application on Glassfish as shown above? I tried by creating two HTTP listeners to listen at port 80, and 443 respectively, but I could not access different applications based on domain names without specifying specifix path or port.
Is there any recommended resources or example of the mapping, or any other suggested solution?

Thank you for your reply nsegura. I created 4 different virtual servers as you suggested and it worked :)
However, I have a problem in reverse proxy base on path.
The scenario is below
I have an J2EE application that needs to be deployed in three different environment (production, training, testing). It
is the same application for three environments, so I want them to have the same context-root. I want to use Sun Web Server 7.0 to reverse proxy to the application in each environment based on path, not URL redirect. Example of URL are shown below
https://sub.domain3.com/app -- > http://localhost:9500 (with context-root /app)
https://sub.domain3.com/training/app -- > http://localhost:9600 (with context-root /app)
https://sub.domain3.com/testing/app -- > http://localhost:9700 (with context-root /app)
So far, it works if I set context-root of the application in each environment differently
https://sub.domain3.com/app -- > http://localhost:9500 (with context-root /app)
https://sub.domain3.com/training/app -- > http://localhost:9600 (with context-root /training/app)
https://sub.domain3.com/testing/app -- > http://localhost:9700 (with context-root /testing/app)
I am wandering whether there is a solution with Sun Web Server 7 that I can use to achieve reverse proxy of the same application in different environments without having to modifying context-root for each environment and use URL redirect?
I was thinking about using rewriting path with reverse proxy, but I did not see this function under reverse proxy tab.
Any ideas?
