com.klavergne.process
Class SmartProcess  

java.lang.Object
  com.klavergne.process.SmartProcess

---

public class SmartProcess

extends java.lang.Object

This class uses the Runtime and Process classes to execute the given command from inside the VM.

While testing this I found that the Runtime class works a little differently than Sun's API documentation says. Their documentation says that Runtime.exec() creates a subprocess without a console window. This is true if using java.exe, but if you use javaw.exe it does create a console window.

Version:

1.0
