Notes/Learnings in Apex Listener

1. Apex Listener is the alternative to mod plsql APEX (the traditional install on top of apache server).
2. Oracle Applications 12.1.3 and Apex Listener can be  used to integrate Oracle Apps with Apex. Prior to this, mod plsql was used (in a hacked/unsupported way) to do the same.
3. Apex Listener 1.1.4 and above can be used with Apex 4.1.1 and above and web services can be consumed as well as delivered.
4. Apex Listener and Apex installation on db node are mutually exclusive. You still need apex to be installed on the database server using apexins. Apex Listener is an alternative to only modplsql.
5. Standalone Apex Listener does not support https. It is used mostly for debugging purpose.
6. Standalone apex listener seems to expect /i/ as the only alias for images. In my case, it was /apex_images and it worked fine with mod plsql but it appears that standalone apex listener would not accept this and I get a blank page.
