Using Runtime.exec()

Hi All,

I am trying to invoke a Jar file, with command line arguments to the main() method in that Jar file.
So here is the command i am trying to execute

String command = "java lib\test.jar com.test.Test 1234";
Runtime.getRunTime.exec(command);

But that particular jar file is not started after executing the above command.
Please correct me if anything is wrong in this?

Did you test that command on the command line because I would not expect it to work if you are expecting to execute the class com.test.Test located in the jar file.

Specifying the class location that way means you are dependent on your current directory having the "lib" subdirectory.

Why not specify the absolute location?
