EAR deployed on colocated master/slave servers does not wait for the embedded JMS services to startup properly -------------------------------------------------------------------------------------------------------------- Key: WFLY-12778 URL: https://issues.redhat.com/browse/WFLY-12778 Project: WildFly Issue Type: Bug Components: JMS Reporter: Bartosz Spyrko-Smietanko Assignee: Bartosz Spyrko-Smietanko Priority: Major When an EAR containing MDBS is deployed in one of the colocated master/slave servers, the application does not wait for the embedded broker to start up and generates these errors in the logs: {code:java} /14:48:11,134 ERROR [org.jboss.as.controller.management-operation] (Controller Boot Thread) WFLYCTL0013: Operation ("deploy") failed - address: ([("deployment" => "EJB_MDBEAR.ear")]) - failure description: { "WFLYCTL0412: Required services that are not installed:" => [ "jboss.ra.activemq-ra", "jboss.naming.context.java.jboss.DefaultJMSConnectionFactory" ], {code} When the broker is eventually started, these MDBs get deployed and start working fine without any redeployment but these errors are not desirable in the logs. Defining the resource-ref in ejb-jar.xml or annotating with @Resource does not help either. The application should wait for its dependencies to be available.
