I wish to compile a java test app from my main app and emulate standard input and output for this test application. Code which needs to be compiled looks like this

			

			import java.io.*;
			

			

			public class Test
			

			{
			

			public static void main(String[] args)
			

			{
			

			

			try {
			

			BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
			

			String str = "";
			

			

			str = in.readLine();
			

			System.out.println(str);
			

			

			}
			

			catch (Throwable t)
			

			{
			

			t.printStackTrace();
			

			}
			

			}
			

			}
			

		

			

			Process exe_proc = rt.exec("java Test");
			

			

			OutputStream estdout = exe_proc.getOutputStream();
			

			InputStream estdin = exe_proc.getInputStream();
			

			InputStream eerr = exe_proc.getErrorStream();
			

			

			BufferedReader pin = new BufferedReader(new InputStreamReader(estdin));
			

			BufferedWriter pout = new BufferedWriter(new OutputStreamWriter(estdout));
			

			BufferedReader perr = new BufferedReader(new InputStreamReader(eerr));
			

			

			pout.write("Message text");
			

			pout.newLine();
			

			

			String currentLine = null;
			

			int currentChar = 0;
			

			

			while (!pin.ready());
			

			

			while ((currentLine = pin.readLine()) != null) mWind.printlnMessage(currentLine);
			

			

			exitVal = exe_proc.waitFor();
