In directory
sc8-pr-cvs1.sourceforge.net:/tmp/cvs-serv3914/samples/src/java/test/dao
Added Files:
ExampleDAOFactory.java
Log Message:
DAO changes. Allow a factory class to be used for generating DAO instances
(XDT-1068). Also eliminate duplicate finders & create methods in DAO
interface if the bean's finder/create methods have @dao.call tags but
automatic generation is being used (XDT-47).
--- NEW FILE: ExampleDAOFactory.java ---
package test.dao;
/**
* Example of a DAO factory class. To see it in action, edit the
CustomerBMPBean
* to use impl-factory="test.dao.ExampleDAOFactory" in its class-level ejb.dao
* tag instead of impl-jndi="dao".
