Hi,
I am a complete newbie who just tried to run the quickstart example
using Wicket 1.3 (source downloaded from
http://wicketstuff.org/maven/repository/org/apache/wicket/wicket-quickstart/1.3.0-SNAPSHOT/).
After I started the embedded Jetty server, accessing the home page
(http://localhost:8082/quickstart/app/) gave the following error:
WicketMessage: Unable to create page from class
org.apache.wicket.quickstart.Index
Root cause:

Any help in resolving this is greatly appreciated!
