How to get test step response in readyAPI using Java?

Hi All.

     I'm trying to execute ReadyApi test cases from Java. I'm able to execute the test case but I could figure how to retrive the response from test step using java. I need couple of fields from the response to validate externally. Can anyone help me on this? I couldn't find any tutorial or support from the internet. 

		try {
			// Create a test runner object
			final SoapUIProTestCaseRunner runner = new SoapUIProTestCaseRunner();

			// Specify the path to the project file
			runner.setProjectFile("C://Work//sampleproject.xml");

			// Specify the test suite to run
			runner.setTestSuite("TestSuite 1");

			// Specify the test case to run
			// It must be in the test suite specified above
			runner.setTestCase("TestCase 1");

			// Run the test
			// Command the runner to create JUnit-style report
			runner.setJUnitReport(true);

			// Command the runner to create printable report
			runner.setPrintReport(true);

			// Command the runner to open the created report
			runner.setOpenReport(true);

			// Specify the folder to save the report in
			runner.setOutputFolder("C:\\Users\\mwl\\tmp");

			// Start the test run
			runner.run();
		}
		// Handle the exception, if any
		catch (final Exception e) {
			e.printStackTrace();
		}
	}

Above is the code. I have used to execute the test cases. any help would be appreciated.
