You just roll 'em up in a Jar file. I use maven for my builds and it puts a jar together for me. As long as you implemented the interfaces correctly and conform to (what I assume are) the bean standards, jmeter just picks your object up and you get new menu entries in the correct locations and everything.
If you did something wrong, you either don't get a new menu entry for your sampler, or you get one but it has the wrong label, or no label. Or it looks like it's going to work but you can't actually configure the sampler. It's a good idea to pull in the logging classes earlier rather than later, and log everything. Then you can look in your jmeter log and see how far your class got, or if it get anywhere at all. -- Bruce Ide flyingrhenqu...@gmail.com
