Answer 1

You can solve this problem by using the following method:
  private String[] getEnvironmentVariables() {
    final Map<String, String> env = System.getenv();
    final String[] result = new String[env.size()];
    final StringBuilder buf = new StringBuilder(100);
    int i = 0;
    for (Entry<String, String> e : env.entrySet()) {
      buf.setLength(0);
      result[i++] = buf.append(e.getKey()).append('=').append(e.getValue()).toString();
    return result;
  }You just have to execute your command like this now:
Runtime.exec("cmd /C " + getMyCommand(), getEnvironmentVariables(), getMyExecDirectory());The reason why "start" didn't work is, that it is a command executed in a shell, thus you need "cmd /C" to execute start in the cmd. So you can do this as well:
Runtime.exec("cmd /C start " + getMyCommand(), getEnvironmentVariables(), getMyExecDirectory());If you want to to execute "myCommand" in an own process.
