That was it! I guess I should get into the habit of managing maven and then "pushing" those changes out to eclipse with a mvn clean then a mvn eclipse.

Re: Runtime error with TabbedPanel and AbstractTab (I know it's my mistake somewhere)
Hi, Maven should handle your dependencies. Have you added the wicket extensions dependency to your pom.xml? Add this to the 'dependencies' tag of your pom.xml. The Wicket dependency should already be there. org.apache.wicket wicket-extensions 1.3.5 Change the 'version' according to which version of Wicket you use. Eclipse should add Wicket extensions to your classpath when you have this dependency. (maybe with a mvn clean eclipse command) Regards, Daan van Etten Op 8 apr 2009, om 12:49 heeft Branden Tanga het volgende geschreven: Ok, I've been racking my brain for the past few days, and I still cannot solve this. I've even added wicket-extensions.jar to my .m2/repository and rebuilt my eclipse project with the mvn clean and mvn eclipse commands given in the wicket quickstart. When I open up my eclipse project, under m2_repo I can find my wicket-extensions.jar I still get a noclassdeffound runtime error for AbstractTab. It seems as if the classpath that eclipse uses for compiling has nothing to do with the classpath that wicket uses at runtime. How can I print my classpath from within wicket?

Re: Runtime error with TabbedPanel and AbstractTab (I know it's my mistake somewhere)
Ok, I've been racking my brain for the past few days, and I still cannot solve this. I've even added wicket-extensions.jar to my .m2/repository and rebuilt my eclipse project with the mvn clean and mvn eclipse commands given in the wicket quickstart. When I open up my eclipse project, under m2_repo I can find my wicket-extensions.jar I still get a noclassdeffound runtime error for AbstractTab. It seems as if the classpath that eclipse uses for compiling has nothing to do with the classpath that wicket uses at runtime. How can I print my classpath from within wicket? (note: I've already added the directory that contains wicket-extensions.jar to my classpath variable in my .bash_profile, still the same runtime error).

Hi. Seems like you're missing a jar file. The "java.lang.NoClassDefFoundError" means just what it sais. The class can not be found in the classpath. It has nothing to do whether the class is abstract or not. /Jörgen Branden Tanga skrev: Hello all, I'm trying to follow the examples given on wicketstuff.org for TabbedPanel here: http://tinyurl.com/cpzkas My code compiles fine, but when I run it I get a noclassdeffound error for AbstractTab.
