URL needs to invoke java ConnectorServlet, not php

How do I configure the upload URL to ask for the java ConnectorServlet instead of the php connector? I could not find documentation on this.

I have installed the ConnectorServlet but when I try to upload an image, the URL still asks for the php connector. I have been unable to find where to configure it to use the java connector instead. The URL it produces is:

http://localhost:8080/fckeditor/editor/ ... 4576379068

The java language is not listed as an option in fckconfig.js for variables FileBrowserLanguage and QuickUploadLanguage.

Where are the documentation files that explain how to configure this, please?

Thank you.
