DDInit
DDInit is a utility for generating deployment descriptors for applications to be deployed on WebLogic Server. Target a module's archive or folder and DDInit uses information from the module's class files to create appropriate deployment descriptor files.
WebLogic Builder, the graphical user interface for generating and editing deployment descriptors, runs DDInit to generate deployment descriptors. See WebLogic Builder for more information.
In its command-line version, unlike in WebLogic Builder, DDInit writes new files that overwrite existing descriptor files. If META-INF (for EAR or EJB), or WEB-INF (for Web Applications), does not exist, DDInit creates it.
Specify the type of J2EE deployable for which you want deployment descriptors generated by using the DDInit command specific to the type, as described below.
EJBInit
Target a JAR file or a folder containing files that you intend to archive as a JAR file, and EJBInit will generate the ejb-jar.xml and the weblogic-ejb-jar.xml files for the module.
java weblogic.marathon.ddinit.EJBInit <module>
EJBInit looks in folders under the target and finds EJBs (bean class, local or remote home, remote or local interface). Matches interfaces with beans, and determines from that match which home belongs to which bean. In the bean itself it looks for CMP fields. then for relationships between entity beans. From information gathered in this way, EJBInit writes the deployment descriptors.
DDInit supports EJB 2.0. DDInit will provide accurate results for session beans from 1.1, but is not likely to work for EJB 1.1 entity beans.
WebInit
Target a WAR file or a folder containing files that you intend to archive as a WAR file, and WebInit will create web.xml and weblogic.xml files for the module.
java weblogic.marathon.ddinit.WebInit <module>
EarInit
Generate an application.xml and a weblogic-application.xml file for an EAR using this command. Target an existing EAR or a folder containing JAR or WAR files you intend to archive into an EAR file.
java weblogic.marathon.ddinit.EarInit <module>
In WebLogic Builder, EarInit looks recursively at the entire tree under the targeted module. On the command line, you need to already have descriptors for the modules contained in the EAR. application.xml will account for the modules. The generated weblogic-application.xml will be an empty placeholder.
Limitations
- Generated XML representations of relations among entity beans are only accurate for one-to-one relations. For entity beans that already have descriptors, Builder does not refresh relations that have a "many" side.
- Support for generating descriptors for EJB 1.1 beans is not guaranteed; focus is on EJB 2.0
