I'm trying to configure a RemoteChunking task using Spring Boot, Spring Batch and Spring Integrations.
I have configured an activeMQ server and I start configuring Spring Batch following the official docs https://docs.spring.io/spring-batch/4.0.x/reference/html/spring-batch-integration.html#remote-chunking.

It seems work OK, but when the slave finishes a chunk, it sends an response to the master which finishes the job and the slave shows a "timeout error":

I think your problem is on the worker side here:
@Bean
public IntegrationFlow outgoingReplies() {
return IntegrationFlows
.from("replies")
.handle(Jms
.outboundGateway(connectionFactory())
.requestDestination("replies"))
.get();
}
You just send replies and you don't except there anything from the master.
It has to be the one-way
Jms
.outboundAdapter(connectionFactory())
.destination("replies")`
