Hi All,
I am a begginner with JMeter and this is my first post to this
mailing
list, and sorry for perhaps faq questions. If it is, let me know.
Is it possible to do static initialisation in a Java Request Sample
that
uses the parameters set in the panel of the the Java Request Sample
?
Or is
there a better way with other feature of JMeter ( Pre-processor ?)?
I'm not sure what you are trying to do.
The Java Request Sampler is a very basic sampler that allows one to
generate a simple sample response; not sure what static initialisation
has to do with that.
Please explain in a bit more detail what you are trying to achieve,
and then maybe someone can provide suggestions as to how it might be
done.
Regards
JL Pasturel

Sorry, i agree that I was not very clear.
Exactly i don't know how JMeter and Java Request Sample instanciates
threads.
The StandardJMeterEngine creates threads; each Sampler instance runs
in a single thread.
So i wondering if to use static variables ( not final) has a sense
in a Java Request Sample.
No.
My goal, is to share objects ( with sometimes monitored accesses )
between
threads ( for example : a datapool, read by all the threads, counters,
getting a local port not used by others threads ...).
But what are you trying to achieve?
Hope i am more clear ...
Sorry, not really.

Sebb, thanks for the answer about static parameters.
What i did, is a java sampler for a non-supported protocol by JMeter (
Radius ) with an open source library : Tiny Radius.
This protocol is use in Telco to permit authentification of internet home
boxes ( Internet, TV, VOIP ...).
I have to handle a datapool of 10 000 000 lines and to pick rows randomly.
So each thread has it own file descriptor ( RandomAccessFile instance). My
Why not use a file of 10 000 000 lines and read them using CSV DataSet?
Each thread will get the next entry. No need for multiple file descriptors.
Java Sampler runs fine and i can use other features of JMeter ( Listener,
trees...).
The goal of my initial question was about the best practices to handle, for
example, my shared datapool with a random access with JMeter.
See above.
Other feature I look for, is IP Spoofing. I have begun to write a TCP proxy
"out of the box" that handles IP Spoofing.
For now, I have to solve, in the best way, the problem of the affinity of
the session in a transaction or in a conversation ( tracking for example
cookies). Certainly by using regexp. Have you advices about it ?

Yes i have look at this feature, but my needs is to avoid the cache effect at
Radius server level and Database level, so i have to randomize as more as
possible the datas that i inject to my application. Serial reads can allow
caching between each stress.
Thanks for your advices.
