Apex Listener vs. Oracle Application Server... advantages?

Question

Are there advantages to installing Apex Listener over using an existing Oracle Application Server instance to serve Apex applications?
We have an existing application server instance in production. Would introducing Apex Listener and the extra overhead be of any advantage?
Thanks in advance for your thoughts.

Hello "Portal Dude",
Are there advantages to installing Apex Listener over using an existing Oracle Application Server instance to serve Apex applications?APEX Listener introduces some additional features, such as Resource Templates, but lacks some others. Some people might want to migrate from OAS to another JEE Container that doesn't come along with a OHS/mod_plsql. Depending on the JEE Container, you could use AJP for load balancing, avoiding plain HTTP through a firewall, etc.
Would introducing Apex Listener and the extra overhead be of any advantage?The "extra overhead" may be smaller than you think. If you don't need the HTTP_Server component any longer, but can just deploy APEX Listener on the OC4J of your OAS, you might even save some bytes.
For several other aspects, there have been a few posts on that topic in the past:

If there's anything you don't find in either the posts or the documentation, don't hesitate to ask.
