From: Hakan on 25 Jul 2010 14:22 Which is the best way to get the process ID on Windows after spawning a Process object with the Runtime.getRuntime.exec method? A search on the web says that Java has no direct way of doing it, and then several different ways to do it are presented. Thanks. -- Newsoffice.de - Die Onlinesoftware zum Lesen und Schreiben im Usenet Die Signatur l��t sich nach Belieben anpassen ;-)

On my platform , I've used `ps` and `awk` from a bash script to do this; jps looks a little more portable, although the format is subject to change in future releases: What criteria are you using to evaluate the approaches you've examined so far? -- John B.

It is not portable, but your problem definition is not portable. Arne

Use ..Net, not Java, if you need to do this on Windows. -o |
