Submitting scripts to jmeter server
Hi list,
We have a situation where our scripts are fairly short and need to
start frequently, so that the expense of starting up a Java
environment each time is very high compared to the actual script
execution.
Would there be any way to submit test scripts to a running jmeter
server without using Java to do the actual submission? Should I be
looking into Beanshell? Or something like PHP/Java integration?
(http://php.net/manual/en/ref.java.php)
Thanks a lot!

Sebb, thanks for your input. We'll see how it goes!

Why? The memory resources will only increase if you use additional listeners.

Sorry, too complicated to explain - you'll have to look at the JMeter code.
And you will need to keep some of the JMeter code anyway to handle the
responses.

The server expects to receive the script via RMI; there is no such
thing as sending an XML script across.

The scripts can use variables read from files or generated on the fly.
If the test is not known in advance, then I don't see how JMeter can
execute them - it cannot make up its own tests.

Good point, but not an option I think, since the scripts will become
many and that would mean running out of memory resources pretty quickly
on the machine.

Ok, no problem, we can go for some Java programming I guess :)
However, since I'm not really into that yet, I seem to fail in finding
out what the preferred/documented way is to talk to a running jMeter
server through RMI. Could you give me a hint on where to start? Any
pointer to (e.g. jMeter) example code would do.
One more question: Am I correct that the original idea (submit file,
wait for server to execute script, submit next file) will work when
programmed in Java? Or is there no such thing as 'submit XML file to
server'...

Ok, a problem here would probably be that our input files are dynamical,
and thus not known in advance.

Can you not run the scripts in a loop, with suitable delays at the end
of the loop?

Probably not, as JMeter uses RMI for client-server communication.

Can't see how these would help.

The JMeter GUI allows one to run a script, load another file, and then run that.
In theory, this functionality could be added to non-GUI mode.
However you could design a mechanism to define the tests and the
timings, and would then need to do the necessary Java coding.
