Specifying Mapping Information in ejb-jar.xml File

For 2.0 CMP projects, the ejb-jar.xml files stores information on bean-to-bean relationships (mappings) in the <relationship> element. By updating this information in the ejb-jar.xml, the TopLink Mapping editor creates new mappings. You can then update the mapping information (such as reference tables).

If the information does not exist in the ejb-jar.xml file, you can build the mappings in the TopLink Mapping editor, then write the information to the file.
