Hi
I am trying to execute a batch file from within a java application. I do the following:
Runtime rt = Runtime.getRuntime();
rt.exec("cmd /c X:\\Java\\WSAD\\workspace\\xrad2\\webApplication\\xrad\\config\\startup.bat");
But the batch file is not executed. A dos prompt is propted, but the batch file is not executed. Any suggestions please?

Sorry, this does work. Only the echo in the batch file is not displayed.

Right. Java collects the output from a process and makes it available through the Process object returned by exec(). You can call getInputStream() on the Process to get a stream from which you can read the output. If you want it to go to the screen you can just System.out.print() everything you read.

Try "CMD /K start X:\\Java\\WSAD\\workspace\\xrad2\\webApplication\\xrad\\config\\startup.bat"
