Hi Denis, By making the Logger a part of the companion object, it works. However, it also works if I keep the LOG field part of the Service implementation class but annotate it as @transient.

If you put a logger into a field of the service class, it will be serialized together with the service, which doesn't make much sense.You should make the logger a part of a companion object, so it won't be sent over network. Denis ср, 4 апр. 2018 г. в 12:02, Neeraj Vaidya <[email protected]>: Hi Denis, Thanks for your responses. Here is the class I am using. It is also there in github : https://github.com/en-vee/axlrate/blob/axlrate-release-1/axlrate/axlrate-charging/src/main/scala/org/hypercomp/axlrate/charging/loader/AxlRateChargingService.scala When I comment out the LOG member and replace all debug statements with println statements, it works fine. It appears that this is causing the difference. The LOG member is just a wrapper over some Log over slf4j/logback API. And it in turn contains a member called "marker". package org.hypercomp.axlrate.charging.loader import org.hypercomp.axlrate.utils.imdg.AxlRateImdgIgniteService import org.hypercomp.axlrate.core.logging.AxlRateLogger import org.hypercomp.axlrate.utils.imdg.AxlRateImdgMessage class AxlRateChargingService() extends AxlRateImdgIgniteService[AxlRateImdgMessage] { val LOG = AxlRateLogger(classOf[AxlRateChargingService]) override val execute:()=>Unit = () => { LOG.process.debug("Starting execute method") } override val initialize:()=>Unit = () => { LOG.process.debug("Initializing.....") } override val cancel:()=>Unit = () => { LOG.process.debug("Stopping service") } } Regards, Neeraj -------------------------------------------- On Wed, 4/4/18, Denis Mekhanikov <[email protected]> wrote: Subject: Re: Failing to deploy service To: [email protected] Date: Wednesday, 4 April, 2018, 7:43 AM Neeraj, There is no such restriction, as far as I know.What do you mean by "using"? Could you provide this class? Denis ср, 4 апр. 2018 г. в 10:32, Neeraj Vaidya <[email protected]>: On analysing further it seems the field id indicated as “marker” below is actually a member of one of the class instances used inside the service classes. Is there anything restriction as such about using custom classes in a service implementation ?
