Look at the API documentation (and read it) for the Runtime.exec( ... ) methods.

If you're running MS Windows you either have to set the proper file associations or you have to find the correct interpreter given the extension of your script file.

If the script exists in the same location as the java file. I am able to execute the script through java but if the script exists in different location i am not able to execute .. Could someone help

Runtime rt = Runtime.getRuntime();

How to specify if the script exists in different location in unix machine ?

You either have to set your 'path' variable before you start your Java program or you have to supply the absolute path to where your script is stored.

If your script is stored here /path/to/your/script you either have to add the directory /path/to/your to your 'path' environment variable or you have to specify the complete path /path/to/your/script to one of the exec( ... ) methods. The OS needs a way to find your script.
