Running Java class with JMeter (Bean Shell) -

i have written java class use in jmeter, packaged project .jar file , moved file lib/ext folder in jmeter directory. have seen documentation on how proceed give contradictory answers.

the first way use beanshell sampler import package , class, create object of class , run methods way. have used method using example classes more simple file structures of class want run. example classes work following beanshell script.

import tools.jmetertools; jmetertools jt = new jmetertools(); jt.foo(); 

when try use method class want run, states variable declaration error , class cannot found. assume because not understand import exactly, file structure in project little odd.

the second uses beanshell preprocessor add jar class path. method have not been able work @ all, have read many accounts of others finding success. works follows:

addclasspath("directory path jar\lib\ext\foo.jar"); jmetertest jtm = new jmetertest(); jmt.test(); 

would have knowledge of way work better or ideas on how fix import?

the import have been using in beanshell script following:

import client.jmetertest; 

the package line @ top of class following

import com.x.foo.client; 

running external classes beanshell should work fine given following preconditions met

1. your test dependencies located in jmeter classpath.
2. jmeter restart required pick new libraries up

3. you need provide full package name plus full class name (or wildcard) import.

   either

   import com.x.foo.client.jmetertest; 

   or

   import com.x.foo.client.*; 

4. and recommended use jsr223 sampler , use "groovy" language. beanshell interpreter has severe performance issues use "light" variable amendment, converting variable property, etc. generating real load use jsr223 , groovy implements compilable interface , hence can achieve performance similar native java code. see beanshell vs jsr223 vs java jmeter scripting: performance-off you've been waiting for! guide detailed explanation, benchmarking , instructions on installation of groovy scripting engine support.
