Thanks, It looks like that should be possible. I didn’t realise that BeanShell was able to run arbitrary Java classes.
How would I go about putting the Map<String,String> properties into bsh.shared so that other test elements can make use of them? Would iterating through the key set and doing vars.put(key, value); allow me to access them in threads/samplers? Regards, Sam.
