DTD Changes

Migrating EJBs from Application Server 6.x to Application Server 8.2 is done without making any changes to the EJB code. However, the following DTD changes are required.

• The <!DOCTYPE> definition must be modified to point to the latest DTDs with J2EE standard deployment descriptors, such as ejb-jar.xml.

• Replace ias-ejb-jar.xml file with the modified version of this file, named sun-ejb-jar.xml,created manually according to the deployment descriptors. For more details, see http://wwws.sun.com/software/dtd/appserver/sun-ejb-jar_2_1-1.dtd

• In the sun-ejb-jar.xml file, the JNDI name for all the EJBs must be added before ”ejb/’ in all the JNDI names. This is required because, in Application Server 6.5, the JNDI name of the EJB can only be ejb/<ejb-name> where <ejb-name> is the name of the EJB as declared inside the ejb-jar.xml file.

  In the Application Server, a new tag has been introduced in the sun-ejb-jar.xml. This is where the JNDI name of the EJB is declared.

To avoid changing JNDI names throughout the application, declare the JNDI name of the EJB as ejb/<ejb-name> inside the <jndi-name> tag.
