[news.eclipse.platform.pde] How to integrate ProcessBuilder + Job + Mess

[tonee47@xxxxxxxxxxx (John Eke)]

Hi,
I am very new to eclipse plugin development and I have what I believe is a 
simple question.

I am trying to run an external process using the java ProcessBuilder and 
then print its output to MessageConsole. Here is what I am currently doing:

ArrayList<String[]> commands = new ArrayList<String[]>();
		String[] com1 = {"first", "command"};
               String[] com2 = {"second", "command"};
               commands.add (com1);
               commands.add (com2);
		
		for (String[] command: commands)
		{
			final ProcessBuilder pb = new ProcessBuilder(command);
			try {
				pb.redirectErrorStream(true);
				Process proc = pb.start();
				InputStreamReader converter = new 
InputStreamReader(proc.getInputStream());
				BufferedReader in = new BufferedReader(converter);
				String CurLine;
				while ((CurLine = in.readLine()) != null)
					Print (CurLine);
		        //in.close();
			} catch (final Exception e) {
				System.out.println("Failed to start " + Arrays.toString(command) + ": 
" + e);
			}			
		}
	}
	
	private void Print (String s)
	{
		MessageConsole myConsole = findConsole(CONSOLE_NAME);
		MessageConsoleStream out = myConsole.newMessageStream();
		out.println(s);
	}
	
	private MessageConsole findConsole(String name) {
		ConsolePlugin plugin = ConsolePlugin.getDefault();
		IConsoleManager conMan = plugin.getConsoleManager();
		IConsole[] existing = conMan.getConsoles();
		
		for (int i = 0; i < existing.length; i++)
			if (name.equals(existing[i].getName()))
				return (MessageConsole) existing[i];
		
		//no console found, so create a new one
		MessageConsole myConsole = new MessageConsole(name, null);
		conMan.addConsoles(new IConsole[]{myConsole});
		return myConsole;
	}


The first problem (which is probably obvious) is that I am not scheduling 
a job, so the processes cause the workspace to hang till its done. The 
second problem is that the output doesn't show up in the MessgeConsole not 
just till one process is done, but until BOTH processes are done. Once 
both processes are done, this huge chunk of text from both their output 
streams is pasted in the MessageConsole. It would be preferable that the 
output is pasted in the MessageConsole as it is recieved from the external 
process.

I guess my questions are as follows:
1. Is there a separate class that comes with the eclipse api that I can 
use in place of the java ProcessBuilder?
2. Once I use a Job to schedule the processes will the output get to the 
MessageConsole incrementally? Or will it still just come out in one huge 
chunk with the way I have done it?

Help will be much appreciated, and please include cod snippets if you can 
:)

Thanks!!!
