[Exist-development] Adding a web proxy to eXist in the Mountain Lion Server

[Loren C. <lor...@gm...>]

Hello folks,

With the upgrade to Mountain Lion, the Apache server is no longer included.  Apache is part of the Server app that is separate.

I was looking for a way to incorporate eXist with the Mac OS X Server configuration base, so that the proxies can be turned on and off from the Server tools.


Adding the following as org.exist-db.plist to /Library/Server/Web/Config/apache2/webapps adds eXist Open Source XML Database to the web app list and performs a proxy to eXist.

It starts, but does not stop.  The entry does show in the advanced settings.  It does not stop from the GUI.

The following command-line entries will work, but I did get a corruption after I stopped and restarted.


sudo webappctl start org.exist-db
sudo webappctl stop org.exist-db

Can you take a look at my solution and make any suggestions to improve it?  I would love to add this capability with the other Mac enhancement that was created.
