Hi Venkat_C,

are you using javajet or Component kit? if your using kit then either pass the configuration object directly to the method that needs it in service or create a constructor in the service like this

@Service public class myService{ private MyService myservice; public MyService(MyService myservice){ this.myservice=myservice; } }

The create an instance of the service class like this , in either the source class for an input component, or processor for a processing component.

    public CompanyComponent1Processor(@Option("configuration") final CompanyComponent1ProcessorConfiguration configuration,final CompanyComponentService service) {
        this.configuration = configuration;this.service = new  service(this.configuration);
    }

best regards
