Modified: jelly maven.xml project.xml
Added: jelly/src/test/org/apache/commons/jelly/demos
HomepageBuilder.java template2.jelly
template1.jelly
Log:
Added Otto's groovy demo that shows how Jelly can be used as a templating system.
To run it type
maven demo:embed
What would be interesting would be to write the demo in JellySwing rather than Java
:-)
