Installed Eclipse with the Aptana Studio plugin on a 64-bit 12.04 and I am looking for a solution to open all web-related files automatically by Eclipse. I installed Eclipse which works fine and shows up in the Dash.

However trying to change to Eclipse as default editor for certain extension did'nt work since it is not showing up in the list of programs. Aptana is shown, Eclipse is not. Am I missing something here?

I am still rather new at Ubuntu...
