I recorded the log in and log out of the application in Jmeter and while Run is clicked, the following message
"//EX[2,1,["java.lang.IllegalArgumentException/1755012560","Invalid session"],0,7]"
is displayed in the Response data blog while log out or closing the application HTTP request is compiled. Is there any way to compile with out getting this message.
My expectation is that you're missing HTTP Cookie Manager which handles cookie-based authentication and maintains session information.
If adding HTTP Cookie Manager to your test plan doesn't help - record the sametest several times and mention any changes in recorded requests. If they are - you need to perform correlation - the process of extracting dynamic mandatory parameters from previous response and adding them to next request. Basing on your response nature the choices can be in:
According to your response, it seems you are testing a GWT RPC application:
Load Testing and scripting GWTRPC is not easy and almost impossible with Core JMeter only as: - Decoding GWTRPC response is difficult whenever you need to extract some info from response. - Making part of the request Variable is very difficult
If you do not variabilize, as with any other protocol, your load test will not be realistic.
You need for this a plugin:
