Question

I have one main application which launch two other process’s, i just need to launch them as an independent process. like running them-self without using or sharing my main application launcher process memory or cpu.

But when i launch it like this TWO other process do not get executed (well they create TWO new process but not fictional), unless i kill the main process. My plan is to execute it under windows just like THREE command prompt where it execute THREE application.

How do i resolve it so that THREE execution run completely alone?

/*This is Process 1 itself*/
try {

  if (myStock.getOs().equals("Linux")) 
  {
    Runtime.getRuntime().exec("java -cp /var/dist/test.jar main.main");        
    Runtime.getRuntime().exec("java -cp /var/dist/test.jar www.webserver_starter");

  } else {

    /*Windows 7 only*/
    String WindowsTemp = System.getenv("MY") + "\\";
    /*This is Process 2*/
    Runtime.getRuntime().exec("java -cp " + WindowsTemp + "dist\\test.jar main.main");        
    /*This is Process 3*/
    Runtime.getRuntime().exec(
        "java -cp " + WindowsTemp + "dist\\test.jar www.webserver_starter");
  }

} catch(Exception e) {
  System.out.println(e);
}

For Windows use cmd /c start ... where '...' is the command you would like to invoke.

Runtime.getRuntime().exec("cmd /c start java -cp /var/dist/test.jar main.main")

For Linux add & at the end of command to start a daemon process.
