I just tested with Eclipse + ClickIDE and receive the same error when
using the J2EE preview version.
I get this stacktrace:
Caused by: java.lang.ClassNotFoundException: org.apache.log4j.Category
at java.net.URLClassLoader$1.run(URLClassLoader.java:200)
at java.security.AccessController.doPrivileged(Native Method)
at java.net.URLClassLoader.findClass(URLClassLoader.java:188)
at java.lang.ClassLoader.loadClass(ClassLoader.java:307)

at java.lang.ClassLoader.loadClass(ClassLoader.java:252)
at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:320)
... 26 more
Seems that the J2EE preview (Jetty) uses a different version of log4j.
Anybody knows how to resolve this?
Personally I'd just use Tomcat instead of the J2EE preview server:
http://tomcat.apache.org/download-60.cgi
One other thing, you need to setup a Cayenne project before running
your application as described at the bottom
of this page: http://incubator.apache.org/click/docs/click-ide.html
Use the Cayenne modeler to setup your tables and domain classes.
kind regards
