7.8.4. jboss-ejb3.xml Deployment Descriptor Reference

jboss-ejb3.xml is a custom deployment descriptor that can be used in either EJB JAR or WAR archives. In an EJB JAR archive it must be located in the META-INF/ directory. In a WAR archive it must be located in the WEB-INF/ directory.
The format is similar to ejb-jar.xml, using some of the same namespaces and providing some other additional namespaces. The contents of jboss-ejb3.xml are merged with the contents of ejb-jar.xml, with the jboss-ejb3.xml items taking precedence.
This document only covers the additional non-standard namespaces used by jboss-ejb3.xml. Refer to http://java.sun.com/xml/ns/javaee/ for documentation on the standard namespaces.
The root namespace is http://www.jboss.com/xml/ns/javaee.

Assembly descriptor namespaces

The following namespaces can all be used in the <assembly-descriptor> element. They can be used to apply their configuration to a single bean, or to all beans in the deployment by using \* as the ejb-name.
The clustering namespace: urn:clustering:1.0
xmlns:c="urn:clustering:1.0"
This allows you to mark EJB's as clustered. It is the deployment descriptor equivalent to @org.jboss.ejb3.annotation.Clustered. 
<c:clustering>
   <ejb-name>DDBasedClusteredSFSB</ejb-name>
   <c:clustered>true</c:clustered>
</c:clustering>
The security namespace (urn:security)
xmlns:s="urn:security"
This allows you to set the security domain and the run-as principal for an EJB. 
<s:security>
  <ejb-name>*</ejb-name>
  <s:security-domain>myDomain</s:security-domain>
  <s:run-as-principal>myPrincipal</s:run-as-principal>
</s:security>
The resource adaptor namespace: urn:resource-adapter-binding
xmlns:r="urn:resource-adapter-binding"
This allows you to set the resource adaptor for an Message-Driven Bean. 
<r:resource-adapter-binding>
  <ejb-name>*</ejb-name>
  <r:resource-adapter-name>myResourceAdaptor</r:resource-adapter-name>
</r:resource-adapter-binding>
The IIOP namespace: urn:iiop
xmlns:u="urn:iiop"
The IIOP namespace is where IIOP settings are configured.
The pool namespace: urn:ejb-pool:1.0
xmlns:p="urn:ejb-pool:1.0"
This allows you to select the pool that is used by the included stateless session beans or Message-Driven Beans. Pools are defined in the server configuration. 
<p:pool>
   <ejb-name>*</ejb-name>
   <p:bean-instance-pool-ref>my-pool</p:bean-instance-pool-ref>
</p:pool>
The cache namespace: urn:ejb-cache:1.0
xmlns:c="urn:ejb-cache:1.0"
This allows you to select the cache that is used by the included stateful session beans. Caches are defined in the server configuration. 
<c:cache>
   <ejb-name>*</ejb-name>
   <c:cache-ref>my-cache</c:cache-ref>
</c:cache>
