Re: Error while deploying to Tomcat 7

[Dan Retzlaff <dr...@gmail.com>]

Is com.myapp.wicket.IVoteCollection included in multiple JARs? Maybe one in
server/lib and one in WEB-INF/lib? Because those will use different class
loaders, Java thinks they're different classes even though they have the
same name.
