A remote invocation of an EJB included in an application marked as singleton-deployment is not possible without knowlege which server is current running the application in EAP 7.0

Solution Verified - Updated -


  • Why the remote client needs to know which server in the cluster has the singleton-deployment active?
    I expect that remote clients are able to invoke a the EJB method even if the application is marked as a singleton-deployment.
  • If the client is configured with one server of a cluster neither the invocation nor the failover works seemlessly as expected.


  • Red Hat JBoss Enterprise Application Platform (EAP)
    • 7.0
    • 7.1 Alpha/Beta
  • JavaEE application in an EAP cluster marked as singleton-deployment with a deployment-descriptor like followed

    # META-INF/singleton-deployment.xml
    <?xml version="1.0" encoding="UTF-8"?>
    <singleton-deployment xmlns="urn:jboss:singleton-deployment:1.0"/>
