I am using JMeter for load testing, I am creating 1000 threads each sending an http request as follows:

{"email" : "test${__threadNum}@test.com"}

that's working fine, now I need to add a more complicated scenario. I need to pass email encrypted with my custom encryption method.

something like:  {"email" : MyCustomClass.encypt("test${__threadNum}@test.com")}

Is there a way to call custom java classes from JMeter.

actually I want to include my jar, and then call a method from that jar, so far I am not successful. – mmohab May 22 '13 at 12:20
    
where did you put your jar ? are you sure it is fine ? if yes look into jmeter.log and show error – UBIK LOAD PACK May 22 '13 at 12:44
    
i put it in the lib/ext folder – mmohab May 22 '13 at 13:05
    
you must put it in lib not lib/ext – UBIK LOAD PACK May 22 '13 at 13:36

You can use a JSR 223 sampler or preprocessor and use Groovy as underlying language. To do so add groovy-all.jar in jmeter/lib folder.

If you want to use your already existing jar, put it in jmeter/lib also.

what is the syntax to call java methods in jmeter. I expect something like this in the request body {"email" : MyCustomClass.encypt("test${__threadNum}@test.com")} but not sure about the syntax – mmohab May 20 '13 at 19:25
    
See stackoverflow.com/questions/13680350/… for an example – UBIK LOAD PACK May 20 '13 at 20:03
    
The sampler (groovy or beanshell) puts the var using vars.put (''test'', the var) then use it with ${thevar} – UBIK LOAD PACK May 20 '13 at 20:05

The best solution I found is to edit the file BeanShellFunction.bshrc and add java methods there, 

String encryptSession(String email) {
    // TODO encrypt session!
    return new String(email);
}

and then add this to the http request body:

${__BeanShell(encryptSession("test${__threadNum}@test.com"))}}
