Unable to run mutiple class , creating TestNG programtically

I created program that create TestNG xml and run test class & Test cases mentioned with Yes/No

i Created one XLSX file with Class names mentioned and test cases with Yes/No to run test cases (Please refer screen below)

I am created one program that created virtual testng.xml file and run the mentioned classes in xl (Please refer the program down)

                         myClasses.add(cls);

                     {

                                 {                           
                                    //System.out.println("Adding suite:"+map.get("TestCaseName").toString());

                                    xmlInclude.add(new XmlInclude(map.get("TestCaseName").toString()));

                                 }
                     }


                    myTest.setXmlClasses(myClasses);
                     myTests.add(myTest);
                     mySuite.setTests(myTests);
                     mySuites.add(mySuite);
                     myTestNG.setXmlSuites(mySuites);
                     myTestNG.run();



        } catch (ClassNotFoundException e) {
            logger.error("ERROR: TestSuite: " + suite + "- Class not found..!!");
        } catch (Exception e) {
            logger.error("ERROR: Problem while reading test set" + testSetPath
                    + "..!!" + e.getMessage());
        }

    }
}

Actual - Even if i mention multiple class name , it only runs single class with test cases written in that class.

Expected - How can i make to run Multiple class with test cases written in that class.

Can some one help me to this

Thanks in Advance.
