Assembly descriptor namespaces

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 adapter namespace: urn:resource-adapter-binding

xmlns:r="urn:resource-adapter-binding"

This allows you to set the resource adapter for a Message-Driven Bean.

<r:resource-adapter-binding>
  <ejb-name>*</ejb-name>
  <r:resource-adapter-name>myResourceAdapter</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>
