[Building Sakai] Sakai Maven Archetype

[Steve Swinsburg]

Here's your problem:

caused by: java.lang.ClassNotFoundException: manageparticipants.logic.SakaiProxy

Check tomcat shared/lib has deployed the jar that contains this class and that any previous builds you might have done are not doubled up. 
Also, check in the FirstPage.java that the SpringBean injection is injecting the right bean name. If you changed it afterwards that will need updating.

cheers,
Steve
