Using a Proxy Auto-Configuration Script (PAC)
If you have set up the path to a Proxy auto-configuration script in your system, Oxygen XML Developer cannot detect this setting out of the box.
You can create a new folder ([OXYGEN_INSTALL_DIR]\lib\endorsed) in which you should copy two additional Java libraries:
            deploy.jar and plugin.jar. These libraries can be
            found in the [OXYGEN_INSTALL_DIR]\jre\lib folder if the application came with a bundled Java VM (otherwise, in
            the Java VM installation used to run the application).
