I'm not sure, but is there a reason that you cannot just right click the file and click open with "text editor"?

Also, in GNOME the calculator can be opened by going to Applications>accessories>Calculator.

Are you running SUSE with KDE or GNOME. If you are unsure, does your computer open the file manager with Konquerer or Nautilus?

I'm using SUSE with KDE. Actually my question is, i've a JButton ( named as "open Text File" )in my application or project , when i click the button a Text File will have to open, but not like this Applications>accessories>Calculator. OR using shell editor how can i open a Text File...

where i can find the calculator and Text file folder or path in linux as exe
Thanks ..

well there are a couple of "standard" editors in linux but not necessarily everyone will have them, like in windows everyone has notepad

you could do this in a few ways, you could ask them what editor they want via a prompt where they type the path to it, or browse to it, or you could check for the most common editors and ask which they'd prefer to use and let them browse to another if it isn't in the list you found

you could also open up the text file in a text pane type window and let them edit it from there, that way you wouldn't have to open a specific editor for it, and provide a save button or whatever else you needed

Linux doesn't use exe's actually. It really doesn't rely that much on file extensions, they are mostly for the user. If you want to open a program, the easiest way to do it is to open the terminal and type in "kwrite" or "gedit" to open the text editor. so say you want to open foo.txt in your home folder:

 kwrite foo.txt

I hope that answers that question, but i dont know what a Jbutton is!

I assume from your mentioning a JButton that you're trying to launch a native program from inside a Java program? You'll need to look at the Runtime.exec() method.

Runtime (Java 2 Platform SE v1.4.2)
Execute an external program - Real's Java How-to

As far as the full path, that shouldn't be necessary. Just find the name of a text editor you have installed and pass that command to the exec(). If you want to use the shell you can use any number of standard editors: nano, emacs, vi.

The usual thing on Linux is to look at the EDITOR environment variable to see if the user has specified an editor (use System.getenv("EDITOR")). If so, pass the resulting string to exec(). Otherwise fall back to "vi". If I was using your program, that's the behaviour I'd expect.
