Deployement descriptors

Deployment descriptors are a key part of J2EE deployments. THese descriptors describe the contents of various J2EE modules and are used by the container when deploying an application. Standard J2EE deployment descriptors are those mandated by the J2EE specification. The deployment descritpor of each module is stored in the module itself.
Following are the deployment descriptors for each type of modules

  • Enterprise application - META-INF/application.xml

  • Web Module - WEB-INF/web.xml

  • EJB Module - META-INF/ejb-jar.xml

  • Resource Adapter Module - META-INF/ra.xml

  • Application Client Module - META-INF/application-client.xml
