Custom Sampler

I wrote a customer sampler for OAuth (a web request with signature). I can
drop my JAR in lib/ext and everything works. There is just one problem. I
have to change messages.properties to add my text there. There is no easy
way to do this. Currently, I copy the resources to my JAR and make sure my
JAR is loaded first to overwrite the one from Jmeter. Does anyone know a
better way to do this?

I think the resource should be redesigned so it's self-contained in
extensions.

Thanks!

Zhihong

Just implement TestBean - see AccessLogSampler for example.

No.

The sampler is a copycat of HTTP sampler, which doesn't use TestBean. I
don't know Jmeter that well to rewrite the sampler.

I noticed the JDBC sampler implements TestBean. Is there a plan to change
all samplers to TestBean?

Thanks!

Use a TestBean-style sampler which has its own property file(s).
