How many deployment descriptor files does a CMP entity bean deployed on the WebLogic Server have?
Answer:
a. One J2EE specific deployment descriptor and two WebLogic specific deployment descriptors
b. One J2EE specific deployment descriptor and one WebLogic specific deployment descriptors
c. One J2EE specific deployment descriptor only
d. One WebLogic specific deployment descriptor only
Choice A is correct. Deployment descriptors are text documents formatted with XML tags. The J2EE specifications define standard, portable deployment descriptors for J2EE components and applications. BEA defines additional WebLogic-specific deployment descriptors required to deploy a component or application in the WebLogic Server environment.
When packaging an enterprise bean, we need to create an ejb-jar.xml deployment descriptor in the META-INF subdirectory and add entries for the bean. We also need to create a weblogic-ejb-jar.xml deployment descriptor in the META-INF subdirectory and add entries for the bean. If the bean is an entity bean with container-managed persistence, first we create a weblogic-rdbms-cmp-jar-bean_name.xml deployment descriptor in the META-INF directory with entries for the bean. Then we map the bean to this CMP deployment descriptor with a attribute in the weblogic-ejb-jar.xml file.
