Hi Friends,

I am new to hibernate and struts2.

Now i need only for struts2 with hibernate no need for spring.

Hi friends,

if anybody having this same issue just refer the following sample coding. This is simple useful for you to find out the problem.

        return (String) result;
    }
   
}

BaseS2TestCase.java should extends on the test class for unit test like following

public class UserActionTest extends BaseS2TestCase {

           public void testUserMethod() throws Exception{
                UserAction userAction=createAction(UserAction.class, "/", "userMethod");
                 String result=userAction.userMethod();
                assertEquals(result, "success");
}

Have a nice time.
