If you don't explicitly list all the classes (entity classes, listeners etc) then Ebean will search for these in the classpath.
These added methods allow the developer to specify the names of jars that are in the classpath to search (jars that contain entity classes etc).
Previously you would have to rely on the ebean.properties setting:
ebean.search.jars=myJarContainingEntities.jar,myOtherJarWithEntites.jar
... where these jars contain entity classes, listeners etc.
This is in HEAD now.
It would be useful for the notation to support classpath elements in general so that directories should be included or excluded.
It would also be useful to allow wild cards in cases where developers version their jars for example
ebean.search.jars=*Entities*.jar,myOtherJarWithEntites.jar
to support the case where the jar is myJarContainingEntities-1.0-SNAPSHOT.jar
