G'day I wasn't suggesting static for the connection - just to control initialization. Don't let any thread exit from initialization until all have completed initialization. You will need a static variable to keep count of threads that have initialized and a static synchronized method to update it in a thread safe manner. You will also need to tell the sampler the number of threads in the run. You may be able to get this from the environment with a method call or you may have to pass it in.
There are probably other ways to do this if getting the number of threads in the run proves awkward. Ian Blavins Software performance specialist . TEMENOS The Banking Software Company .

Static variables would be a good idea, however, I require that each thread has it's own connection, in order to simulate multiple separate users. Sharing a connection through a static variable would break my test unfortunately. For some reason, the system I am testing requires that all connections are established before any of them are used. Therefore I really need to ensure all the setupTest methods are invoked before any of the runTest methods are invoked.
