Launching SOAPUI test with JUNIT : handcheck Fail

Hi, I'm actually working on a project which consist in launching the SOAPUI test using JUNIT.
Using the code I've found on the website I can do it so far, I'm able to execute the test Suite until I reach the call of a Webservice (when the request is send). Then I encountered a handcheck fail certainly due to the usage of certificate (ssl) ...

My Junit test file is as follow, I'm not managing any certifate issue

 
      WsdlProject project = new WsdlProject( "D:\\Test-simu-auto-soapui-project.xml" ); 
      TestSuite testSuite = project.getTestSuiteByName( "testsuite" ); 
      TestCase testCase = testSuite.getTestCaseByName( "testcase" );
      final TestRunner runner = testCase.run(new PropertiesMap(),false);

Running the testCase using directly SOAPUI works because these certificate are configured in the soapui I'm using but I don't know how.
I've found different configuration file in this soapui configuration : certificate, KeyStore for the client and server

I guess I'll have to use these file in order to make it work, the problem is that I don't know how to use them ... Does someone have an idea concerning my problem ?

p.s : As I'm running the test using Junit, and as it's modifying some informations in the project which I need to save for futures runs, I'm wondering if there is a way to tell soapui to save the project at the end of the running of a testcase (using groovy script for example). When I'm launching the test with SOAPUI I have to click on file > save project or else the data won't be updated and so future run won't work properly.

Thanks !
