Hi,

I need a functionality similar to the "open" function in the
(windows)explorer. "open" a file with the corresponding application. Is
there something?

I can use Runtime.exec() only with the application name. I would favour a
more flexible way because at programming time are not all types of
applications known.
(btw: is it possible to get registered applications from the os (like Word
for *.doc, *.dot)?)

Ralph

This is fairly windows-specific functionality, but at least on Windows,
you can easily emulate this by doing the following (provided that the
file extension is already registered with Windows):

  String[] args = { "cmd", "/c", "start", yourfilename };
  Process p = Runtime.getRuntime().exec(args);

(You'll have to do some OS checking: for WinME, 98 and 95, you'll have
to use "command" rather than "cmd", but otherwise the same syntax).
