How to execute test cases in sequential mode or sequential order using multiple classes

Question

I'm executing a test with multiple classes in sequence mean the login should be done dann the content should be executed, when run in one file everything work fine. but in two different classes the first work but the second is not reach. i don't know, what i'm doing wrong here!!! if it's my xml file needed to be configure or how to make the second class getting information from first class to execute test with.
