19.3. Stateless Session Bean in EJB 2.x

EJB 2.x is not supported

EJB 2.x is included, but not supported, in JBoss Enterprise Web Platform, and may not be available in future versions.

To make an EJB 2.x bean clustered, you need to modify its jboss.xml descriptor to contain a <clustered> tag.

<jboss>
  <enterprise-beans>
    <session>
      <ejb-name>nextgen.StatelessSession</ejb-name>
      <jndi-name>nextgen.StatelessSession</jndi-name>
      <clustered>true</clustered>
      <cluster-config>
        <partition-name>DefaultPartition</partition-name>
        <home-load-balance-policy>org.jboss.ha.framework.interfaces.RoundRobin</home-load-balance-policy>
        <bean-load-balance-policy>org.jboss.ha.framework.interfaces.RoundRobin</bean-load-balance-policy>
      </cluster-config>
    </session>
  </enterprise-beans>
</jboss>

partition-name: Specifies the name of the cluster the bean participates in. The default value is DefaultPartition. The default partition name can also be set system-wide using the jboss.partition.name system property.
home-load-balance-policy: Indicates the class to be used by the home stub to balance calls made on the nodes of the cluster. By default, the proxy will load-balance calls in a RoundRobin fashion.
bean-load-balance-policy: Indicates the class to be used by the bean stub to balance calls made on the nodes of the cluster. By default, the proxy will load-balance calls in a RoundRobin fashion.
