JMeter 2.10 Random Variable that gets data from string -

i have 1st thread group gets id's , writes variable. var has view "654564546,564564,56454,56456454,21231321,8972341,65423187". need pick randomly 1 of id , put variable. in jmeter 2.07 used code:

import java.util.random;  string[] erroridcox = (vars.get("erroridcox")).split(",");  int id1 = new random().nextint(erroridcox.length); string randerror = (erroridcox[id1]);  vars.put("rnd_erroridcox", randerror); 

but in jmeter 2.10 code doesn't work. jmeter log says:

jmeter.util.beanshellinterpreter: error invoking bsh method: eval   sourced file: inline evaluation of: ``import java.util.random;  string[] erroridcox = (vars.get("erroridcox")).split( . . . '' : typed variable declaration  

your code looks good, possible failure point erroridcox variable not being set.

add debug sampler , view results tree listener double-check erroridcox , rnd_erroridcoxvariable values.

also can put debug(); function @ beginning of script , stdout observe flow - provide sufficient information figure out cause.

see how debug apache jmeter script more debugging techniques explained.
