Derek,
JMeter testing JavaSpaces sounds very interesting. I hope you will
consider contributing your code to Apache.
To answer your questions:
1a. It's function was to record results to file. In 1.7.1, any visualizer
can record results to file. All visualizers store the same results, thus a
file saved using Graph Results can later be opened by the View Results Tree
visualizer, and vice versa.
1b. See above. Select a file (exiting or non-existing), then run your test.
The file will be created/appended to.
1c. Writing the server response to file can be time consuming. If the
server returns 1 MB of data, all this gets written into the results file if
functional test mode is on. Otherwise, it is skipped. Only use functional
mode if you explicitly want to save all the response data so you can look at
it later and verify your server is doing what is expected. Even so, this
only applies to saving data to file. With functional mode off, the listener
attached the the test will get all the data - it just won't save it to file.
Regarding log4j - thanks for the info. Personally, I don't know much about
log4j and have no motivation to do so. But I will try your suggestions.
The reason I put that there is because it wasn't working anyway, so I
thought I'd try setting it explicitly. When that didn't work, I gave up and
worked on other things.
You mention running your extensions under 1.7.1 - so you converted to the
new architecture? What was the class it couldn't find?
