JBoss Application Server (IV)
1 April 2008In the post, I will talk about the deployment process which shows how to deploy applications on a JBoss application server.
Enterprise beans are packaged in a JAR file (Java ARchive) with the appropriate XML files in the META-INF folder. Most J2EE app servers require the deployment of an EJB JAR within a WAR (Web ARchive) file, and even within an EAR file (Enterprise ARchive). The process of packaging up an enterprise bean with deployment descriptors into a larger archive with its deployment descriptors can become rather complex. This process may be necessary in a production environment, but in development, you need quick, efficient deployment. JBoss provides the best of both worlds.
In order to deploy EJBs in JBoss, simply drop the archive into the deploy directory. The JBoss engine immediately inspects the contents of the archive and attempts to deploy the beans. To undeploy, simply delete the archive from the deploy directory.
Following features make deployment process highly efficient with JBoss:
- supports the deployment of EJB JARs contained within WARs and EARs
- supports the native deployment of EJB JARs
- does not require the inclusion of the server-specific XML file unless specific changes are made
