I would like to test the server with jmeter from echo server. Once it was sent to the server, it was successful. But the class I use is only a number. How to get a sentence in the jmeter?? this is first question.
The second problem can be seen from the photograph. response message is ok but i have beanshall error in the code. How to fix that?
