Extending Zorka lib

[Samraj Subramaniam]

I want to use Zorka spy to capture method duration and put this statistics in a JMS queue which will be used for further processing the statistic. I tried to introduced a method called logDuration in ZorkaLib.java that will put method statistics into JMS queue 

The signature of the method is as follows

    public void logDuration( String text, String startTime, String endTime )

So that I can use this logDuration in bsh scripts. My script looks like this

spy.add(spy.instance("REPORT_ENCRYPTION_REQUESTS")

  .onEnter(spy.fetchArg("INTOKEN", 1),spy.fetchTime("STARTTIME"), spy.zorkaLog("INFO", "SKP", "Invoking crypto services to get the token: ${INTOKEN}. Stefan"))

  .onReturn(spy.fetchTime("ENDTIME"))

  .onSubmit(zorka.logDuration("Crypto execution :", "STARTTIME","ENDTIME"), spy.tdiff("STARTTIME", "ENDTIME","EXETIME"), spy.zorkaLog("INFO","SKP", "Execution time of encrypt : ${EXETIME}"))

  .include(spy.byMethod("com.skp.spkreports.service.CryptoREST", "changePassword")));

When I try to execute the above script, I get the following exception

2016-04-26 16:46:04 DEBUG ZorkaBshAgent Error executing script encrypt.bsh [com.jitlogic.zorka.deps.bsh.EvalError: Sourced file: /opt/camunda/jboss/server/jboss-as-7.2.0.Final/zorka-1.0.15/scripts/encrypt.bsh : Undefined argument: zorka .logDuration ( "Crypto execution :" , "STARTTIME" , "ENDTIME" )  : at Line: 4 : in file: /opt/camunda/jboss/server/jboss-as-7.2.0.Final/zorka-1.0.15/scripts/encrypt.bsh : ( zorka .logDuration ( "Crypto execution :" , "STARTTIME" , "ENDTIME" ) , spy .tdiff ( "STARTTIME" , "ENDTIME" , "EXETIME" ) , spy .zorkaLog ( "INFO" , "SKP" , "Execution time of encrypt : ${EXETIME}" ) )

Can you please help me to resolve this problem?

Thank you.

Solved the problem. It was so stupid from my side. If we want to use a method in Spy onSubmit or onReturn, it should be of the type SpyProcessor. Impletemented a class that implements SpyProcessor and added a method in SpyLib class like below

public SpyProcessor logDuration( String text, String startTime, String endTime )
