SingletonServiceTest-ejb

Description

Testing applications for HA singleton MSC services. Each of the applications will be deployed on all cluster nodes, but the service will be active only on one node at any given time.

The project is structured into 4 main modules with 1 additional module for manual testing:

Public API (api)

This is built with Java target 6, because of some internal implementation details.

  • ServiceAccess, the @Remote interface exposed by ServiceAccessBean (see below) that provides the functionality of the singleton service

Common Classes (common)

Classes that are shared between the startup-ejb and service-activator modules (see below).

  • TestingSingletonService, which is an HA singleton service that provides current node name, which is the name of the cluster node where the service is currently running
  • MyTimerBean, which is a @Singleton EJB that shows how to create a HA singleton EJB timer; it provides two methods:
    • initialize, which creates an EJB timer that logs a message each second; this method is called by the TestingSingletonService during activation
    • stop, which cancels the previously created EJB timer; this method is called by the TestingSingletonService during removal
  • ServiceAccessBean, which is a @Stateless EJB that exposes the TestingSingletonService to EJB clients

Startup EJB + Custom Singleton Policy (startup-ejb)

An application that activates the singleton service using a @Singleton @Startup EJB and uses a custom, in-place built singleton policy.

  • SingletonStartupBean, which is a @Singleton @Startup EJB that installs and activates the TestingSingletonService during @PostConstruct and removes it during @PreDestroy

Service Activator + Policy from Singleton Subsystem (service-activator)

An application that activates the singleton service using ServiceActivator and uses a singleton policy defined in the singleton subsystem.

  • SingletonActivator, which is a ServiceActivator that installs and activates the TestingSingletonService

Standalone Client for Manual Testing (client)

  • Main, which is a Java application that uses JBoss EJB Client to invoke the ServiceAccessBean remotely; it is not used for automated tests, but can be easily used for manual testing when required

Build

The standard Maven incantation is everything you need: mvn clean install. Maven 3 is assumed.

Versions

Major version number is the generation number of JBoss EAP that is targeted by the applications. Minor version number is specific to this application.

SingletonServiceTest-ejb
Description
Testing applications for HA singleton MSC services. Each of the applications will be deployed on all cluster nodes,
but the service will be active only on one node at any given time.
The project is structured into 4 main modules with 1 additional module for manual testing:
Public API (api)
This is built with Java target 6, because of some internal implementation details.
  • ServiceAccess, the @Remote interface exposed by ServiceAccessBean (see below) that provides the functionality
of the singleton service
Common Classes (common)
Classes that are shared between the startup-ejb and service-activator modules (see below).
  • TestingSingletonService, which is an HA singleton service that provides current node name, which is the name
of the cluster node where the service is currently running
  • MyTimerBean, which is a @Singleton EJB that shows how to create a HA singleton EJB timer; it provides two methods:

    • initialize, which creates an EJB timer that logs a message each second; this method is called by the
TestingSingletonService during activation
    • stop, which cancels the previously created EJB timer; this method is called by the
TestingSingletonService during removal
  • ServiceAccessBean, which is a @Stateless EJB that exposes the TestingSingletonService to EJB clients
Startup EJB + Custom Singleton Policy (startup-ejb)
An application that activates the singleton service using a @Singleton @Startup EJB and uses a custom, in-place built
singleton policy.
  • SingletonStartupBean, which is a @Singleton @Startup EJB that installs and activates the TestingSingletonService
during @PostConstruct and removes it during @PreDestroy
Service Activator + Policy from Singleton Subsystem (service-activator)
An application that activates the singleton service using ServiceActivator and uses a singleton policy defined
in the singleton subsystem.
  • SingletonActivator, which is a ServiceActivator that installs and activates the TestingSingletonService
Standalone Client for Manual Testing (client)
  • Main, which is a Java application that uses JBoss EJB Client to invoke the ServiceAccessBean remotely;
it is not used for automated tests, but can be easily used for manual testing when required
Build
The standard Maven incantation is everything you need: mvn clean install. Maven 3 is assumed.
Versions
Major version number is the generation number of JBoss EAP that is targeted by the applications.
Minor version number is specific to this application.
