Configuring Descriptor Alias

Use the descriptor alias to specify the value of the ejb-jar.xml attribute abstract-schema-name. This is the logical name that is referenced in EJB QL queries. You should configure a descriptor alias for each CMP entity bean. The descriptor alias defaults to the class name.

Descriptor alias only applies in projects where you configure the persistence type (see "Configuring Persistence Type") to use EJB.

Table 28-6 summarizes which descriptors support descriptor alias configuration.
