[noob]Problem with TOS .bat

[fred33]

Hello,
I'm working with eclipse and i've a problem to launch an Talend .bat
I want to start a Talend job behind a jbutton.
This is my code :

Code:

try {
						String[] cmd = new String[3];
						cmd[0]= "cmd.exe";
						cmd[1]= "/C";
						cmd[2]= "C:\\workspace\\Test\\TestPgmJava_run.bat";
						Runtime rt = Runtime.getRuntime();
						final Process proc2 = rt.exec(cmd);
						new Thread() {
							public void run() {
								try {
									BufferedReader reader = new BufferedReader(new InputStreamReader(proc2.getInputStream()));
									@SuppressWarnings("unused")
									String line = "";
									try {
										while((line = reader.readLine()) != null) {
											// Traitement du flux de sortie de l'application si besoin est
											System.out.println("erreurint: "+line+"\n");
										}
									} finally {
										reader.close();
									}
								} catch(IOException ioe) {
									ioe.printStackTrace();
								}
							}
						}.start();

//						 Consommation de la sortie d'erreur de l'application externe dans un Thread separe
						new Thread() {
							public void run() {
								try {
									BufferedReader reader = new BufferedReader(new InputStreamReader(proc2.getErrorStream()));
									@SuppressWarnings("unused")
									String line = "";
									try {
										while((line = reader.readLine()) != null) {
											// Traitement du flux d'erreur de l'application si besoin est
											System.out.println("erreur1 : "+line+"\n");
										}
									} finally {
										reader.close();
									}
								} catch(IOException ioe) {
									ioe.printStackTrace();
								}
							}
						}.start();
						proc2.waitFor();
						int status = proc2.exitValue();
						System.out.println("valeur de retour du sous proc2: "+status);
					} catch (Exception e3) {
						// TODO: handle exception
						e3.printStackTrace();
					}
					}
				});
			}
		return jButton;
	}

When i start the program i have this error message
erreurint:

erreurint: C:\workspace\Test>java -Xms256M -Xmx1024M -cp ../lib/jt400.jar;../lib/jxl.jar;../lib/systemRoutines.jar;../lib/userRoutines.jar;.;testpgmjava.jar;../lib; projet_corep.testpgmjava.TestPgmJava --context=Default

All the .jar are in c:\workspace\test\lib
