erstmal nen frohes neues Jahr
![Wink ;)](./images/smilies/icon_e_wink.gif)
Ich habe leider ein Problem... Bei folgendem Code bekomme ich immer eine nervige Fehlermeldung...
Der Prozess (wird noch einwandfrei ausgeführt):
Code: Alles auswählen
ProcessBuilder pb = new ProcessBuilder();
pb.command().add( "cmd" );
pb.command().add( "/c" );
pb.command().add( "***");
Code: Alles auswählen
Process p = null;
try {
p = pb.start();
} catch ( IOException e ) {
e.printStackTrace();
}
Scanner s = new Scanner( p.getInputStream() );
// System.out.println( s.next() );
s.close();
errorlevelcopy = p.exitValue();
Hat jemand eine Idee?Exception in thread "AWT-EventQueue-0" java.lang.IllegalThreadStateException: process has not exited

EDIT:
Habe nun mal folgendes geändert und es scheint zu funktionieren:
Code: Alles auswählen
try {
p = pb.start();
errorlevelcopy = p.waitFor();
} catch ( IOException | InterruptedException e ) {
e.printStackTrace();
}
