That link refers to the old Runtime.exec method, which was mostly superceeded in Java 1.5 by the ProcessBuilder class - the doc is in the usual places..

thank you for your answer, i tryed to do it by this code but it doesn't work : this is my code

Runtime runtime = Runtime.getRuntime();
Process process = runtime.exec(new String[]{"Microsoft Visual C++ 2010 Express.exe", "readxmlresou.exe"}, null, new File("C:\\Users\\abdelhalim\\Desktop\\"));

the compiler get me this error :

Exception in thread "main" java.io.IOException: Cannot run program "MicrosoftVisualC++2010Express.exe" (in directory "C:\Users\abdelhalim\Desktop"): CreateProcess error=2,The specified file is not found

and im sur that i have "readxmlresou.exe" in that directory??????

Use ProcessBuilder, not Runtime.exec

also: exception handling is great, but exception avoiding can help as well.
write a test that checks whether or not that file exists on your system, before trying to run it.
