JBoss Enterprise Application Platform (EAP) deployment plans

To be honest with you, I have never heard of deployment plans before. I was aware of deployment descriptors, but not deployment plans.

A bit of searching turned up this bit of information:

Every J2EE application module must include an XML based deployment descriptor that provide configuration information for the asset as well as defining relationships to other components.

There are two types of deployments descriptors:

  • vendor neutral deployment descriptors (a.k.a deployment descriptors)
  • vendor specific deployment descriptor (a.k.a deployment plans)
Deployment descriptors are necessary but are not always sufficient to deploy an asset on your server. Deployment plans provides additional information to map declared resources names, ejb names, security roles, JMS roles (if any) to actual resources in the server. The deployment plans also contain specific server settings and configurations.

So we are looking at a vendor specific deployment descriptor file for the various application modules use. Now I was curious to those for JBoss, so dug around a bit and have come up with this overview.

Vendor neutral:
J2EE module file type Standard deployment descriptors
Enterprise Application Archive (EAR) META-INF/application.xml
Web Application Archive (WAR) WEB-INF/web.xml
Jar containing Enterprise Java Beans (JAR) META-INF/ejb-jar.xml
J2EE Connector Resources Adapter Archive (RAR) META-INF/ra.xml
Enterprise Application Client Archive (JAR) META-INF/application-client.xml

JBoss specific (EAP):
J2EE module file type JBoss deployment plan
Enterprise Application Archive (EAR) jboss-app.xml
Web Application Archive (WAR) jboss-web.xml
Jar containing Enterprise Java Beans (JAR) jboss.xml
J2EE Connector Resources Adapater Archive (RAR) ---
Enterprise Application Client Archive (JAR) jboss-client.xml

There you go, happy deployment planning!
