Attaching external script file to SAP Java GUI on Linux

Hi,

I am looking for a way to run a script file externally on Linux that attaches onto the GUI and does the remaining automation tasks.

Currently, the only means of running a JS file is via the scripting menu.

To simplify, how could I get access to the "application" object of an existing session of SAPGUI JAVA in an external JavaScript file?

Thanks a lot
