Redirecting process output to jtextarea

Question

I'd like to redirect the output of a process to a JTextArea that is continuously updated as the output comes in. Can anyone help me with this?

Answer 1

I'm basically confused as to how to do this.
I have the following class that I obtained from a site.
There's an example posted as to how to redirect system error ouput to a JTextArea using the Stream class below. I want to take the ouput of a launched process, and send it to a textarea.
import java.io.IOException;
import java.io.OutputStream;
import javax.swing.JTextArea;
public class TextAreaOutputStream extends OutputStream{
       private JTextArea textArea;
       private StringBuffer buff;
       public TextAreaOutputStream(JTextArea textArea){
         this.textArea = textArea;
         this.buff = new StringBuffer();     
       public void write(int b)throws IOException{
         // this next line is kind of a hatchet job... it works... but still
         buff.append(Character.toString((char)b));
         if(buff.length()>100){
           flush();     
       public void flush()throws IOException{
         this.textArea.append(buff.toString());
         this.buff = new StringBuffer();
       public void close()throws IOException{
         this.textArea = null;
         this.buff = null;
     }So I'd like to launch my process, and direct all output from that process to a Jtextarea? Is there a rough overview anyone can give me as to how this can be done?
