Ok,
I will have to investigate a bit about the current state of Scala
implementation of JSR223 interface. AFAIK it's already implemented since
Scala 2.11.
To support JSR223 scripting means Scala must provide a class that
implements the interface javax.script.ScriptEngine.
To support compilation as well as run-time interpretation, the class
must also implement the interface javax.script.Compilable.
I have tested a simple ScriptEngine with scala 2.11.4 and it appears to
implement Compilable.
ScriptEngine scalaEngine = new
ScriptEngineManager().getEngineByName("scala");
if (scalaEngine instanceof Compilable) {
System.out.println("OK");
}
prints out "OK".
Thanks!
So long as the Compilable.compile(Reader script) method actually works
(*), this should allow scripts to be processed much more efficiently.
(*) BeanShell implements compilable but throws Error: unimplemented -
which is very unhelpful!
I tried to go a bit further. To compile stuff, I had to set the jvm
parameter -Dscala.usejavacp=true. With that the code
ScriptEngine scalaEngine = new
ScriptEngineManager().getEngineByName("scala");
Bindings bindings = scalaEngine.getBindings(ScriptContext.ENGINE_SCOPE);
bindings.put("n", 23);
if (scalaEngine instanceof Compilable) {
Compilable compilableEngine = (Compilable) scalaEngine;
CompiledScript compiledScript =
compilableEngine.compile("n.asInstanceOf[Int]");
ScriptContext context = scalaEngine.getContext();
System.out.println(compiledScript.eval(context));
bindings.put("n", 42);
System.out.println(compiledScript.eval(context));
}
runs, but will print "23" two times instead of 23 and 42. So it seems
the context is not re-evaluated correctly.

Felix
I will give it a try, although it's still not very clear how I
would do this with Jmeter, I think I am missing some core concepts here
with JSR233.
I will really appreciate it If you can give me some lights of where I
should focus my research.
Thank you.

Hello,
This is already possible through JSR223 Family.
But last time we tried it, as JSR223 Engine didn't seem to support
Compilation (as Groovy does) performance were just awful making it
unusable.
Maybe this has changed , tests are welcome.
I compilation is still not supported, maybe you could open a feature
request on the scala project.

Hello guys,
I would like to know if we have a plan to introduce a
sampler/{pre,post}-processor using Scala Language.
Would this make sense ? If so, I would be really interested on
implementing
it.
Cheers !
