Hi. I would like to know how to store the response data in the above code.

Hi, Thank you very much for sharing this code. However I wanted to store the JMeter files in a remote directory and hence I was hoping if there was any way to change the below line of code, so that it would accommodate the remote directory path.
File jmeterHome = new File("E:\\rivetsys\\servers\\apache-jmeter-2.11\\apache-jmeter-2.11\\apache-jmeter-2.11");

Please share some insight onto this.
