No you havent. > Please don't top post. +1 The idea is simple. Don't look for ready made answers. First look for how to execute a native process from Java. You will find this: http://java.sun.com/j2se/1.4.2/docs/api/java/lang/Runtime.html so, you can do something like Runtime.getRuntime().exec("command") Now, you want to pipe the input and output. Lets see how we can do that. Looking at the method signature of "exec()" public Process exec(String command) throws IOException The method returns an object of the class "Process". What does Process have? It has a getInputStream() and getOutputStream(). Use these to read the inputStream which is actually the output of the process and you can write to the outputstream, which is actually the input to the process. READ: http://java.sun.com/j2se/1.4.2/docs/api/java/lang/Process.html I did not understand one part of the question. What does java GUI have to do with executing the command here? The above mentioned stuff can simply execute a command. Java GUI has nothing to do with this. you are welcome to write GUI code using AWT, SWT or SWING, and use the above classes. BUT, do you really want to do this? The main purpose of writing a program in Java is to make it cross platform. The moment you start using "exec()" with hardcoded Linux commands inside it, you just defeat the purpose of the Java. You can very well rewrite your code in C/C++? can't you? Sometimes, you might even be using native commands, just because you don't know enough of Java? may be? with regards, Natarajan. _______________________________________________ ILUGC Mailing List: http://www.ae.iitm.ac.in/mailman/listinfo/ilugc
