Andrea and Piero, It sounds like your doing something very similar to how our product communicates. I developed the JMeter protocol so we could do performance testing. I've attached a zip file with some documentation and a couple of classes I use to test our application.
The purpose of the Java Protocol is provide a way for JMeter users to write code which can be run as part of JMeter. This is similar to Mercury LoadRunner "rmi" protocol. The user created code needs to be in a jar file placed in the JMeter lib/ext folder. The user code needs to implement the JavaSamplerClient interface. The interface defines the methods needed to tie into JMeter. Jmeter looks for all the classes which implement JavaSamplerClient and displays them in the dropdown menu. I provide the SleepTest class as an example. The user can pass parameters into their code by setting the parameters in the interface. In the example source code, LoadTestRunner, I pass in the URL of the servlet and the name of the test script file. The runTest method actually executes each test case. The method must fill in the necessary SampleResult data. Again, LoadTestRunner provides an example of how I populate the SampleResult data. I do some "tricks" to capture the data and form! at it s o it can read into Excel. I have an XSLT file to convert from XML to a comma separated value file for Excel. The whole point of the JavaProtocol is to have explicit control over the messages sent to the application being tested. I actually use our communication methods to send the messages. That way the message is formatted correctly whether you're serializing objects or using a proprietary encryption technique. Please review the material I've provided and let me know if you have more questions. Happy performing!

The client, an applet, serializes a java object and de-serializes another one from the response. We read your post on jmeter-dev mailing list and it seems very interesting, where can we find further information on your Java Protocol Extension? Thanks in advance, Andrea and Piero Team XPLayers at Quinary
