This is related to my previous email thread, but slightly different
circumstances.
Apache Tomcat 6.0.14
Java 1.6.0_02-b05
Wicket 1.3.0-beta3
I'm trying to run a Wicket application and it's not working. I'm getting a
NoClassDefFoundError:
java.lang.NoClassDefFoundError:
org/apache/wicket/protocol/http/WebApplication
I think I must be misunderstanding something basic about Tomcat web
application deployment.
So, I create a basic "HelloWorld" type servlet to try and troubleshoot the
problem.
I've double- and triple-checked the package against the documentation and
even verified it by listing the contents of the JAR with unzip.
What am I doing wrong?
The Wicket JAR file and two of its dependencies are in WEB-INF/lib:
