Open "vi" Editor from java

[Raed Qudaisat]

Hello
Plz I need your help;;;
I am writing a java programe that has to open the "vi" editor, on linux Operating System..

I tried this code
Runtime.getRuntime().exec("vi test.txt");

but it didn't work,,

Any idea plz???

What was the output? It should have opened it somewhere, maybe you're not seeing it.

The way it is executed, it may not have opened anywhere. To do that, you need to execute a shelltool or xterm first -- which then can run the "vi" command.

thanx for answering,,
what do you mean by you need to execute a shelltool or xterm first???

any example code plz???

I'm writing a console application that draw a screen and show all of it's contents files "available files" the user will choose the wanted file with arrows,, and when his/her wanted file is highlighted he can press return "enter" to open his/her file with the "vi" editor.....

i wrote this for proop of concepts

************
Runtime rt = Runtime.getRuntime();
Process ps = rt.exec("vi test.txt");
OutputStream os = ps.getOutputStream();
InputStream is = ps.getInputStream();
DataOutputStream dos = new DataOutputStream(os);
dos.writeBytes("i");
dos.writeBytes("test");
dos.writeBytes("\u001B");
dos.writeBytes(":wq\n");
dos.flush();
ps.waitFor();
dos.close();
System.out.println(ps.exitValue());
****************
and a "test.txt" file has been created with a inner-text "test".....

i don't want to get the output stream for the Process to wrtie on the file,,, i hope if i can display it for theuser to do his/her modifications


thanx again
