How do I use print() with variables?

[Marc Anthony Winoto <ma...@netregistry.com.au>]

While trying to reproduce Philip's BeanShell problem, I found some strange behaviour.

HTTP Sampler
|
|-Regex: test, (the), $1$, 1, "fout"
|
BeanShell PostProcessor or PreProcessor: print(${test}); or print(""+${test});
|
|
HTTP Sampler: go to http://${test}

The bean shell never got a value for test. I can print out hardcoded strings and predefined 
variables though.

The 2nd HTTP sampler does get a correct value from the test variable and tries to go to 
http://the (and fails).

I also tried putting the beanshell as a child of the first http sampler. Nothing. What's going on?

This would be interpreted as

print(the); or print(""+the);

which is not valid unless you define the BeanShell variable "the".

JMeter variables are replaced *before* the script is passed to Beanshell.

To print a JMeter variable in BeanShell, you need to use:

print("${VAR}"); or print(vars.get("VAR"));

See also other thread - Post-Processors are run in reverse order
(don't know why yet).
