svn commit: r332150 - in
/portals/jetspeed-2/trunk/components/registry/src/java/org/apache/jetspeed/om/impl:
LanguageImpl.java LanguageSetImpl.java
Author: ate
Date: Wed Nov 9 13:35:19 2005
New Revision: 332150
URL: http://svn.apache.org/viewcvs?rev=332150&view=rev
Log:
Major rewrite of the Language and LanguageSet implementations to get them in line with the portlet specs.
Now the (possibly merged) title, shortTitle and keywords are actually retrievable from the resourceBundle itself.
