RE: Error during start of wicket application
Seems like a classpath issue.

Re: Error during start of wicket application
I'm using Intellij myself and with that, in the Project overview I see a list of dependencies projects are using. With that I can quickly see if I'm using multiple versions of a certain dependency. This same type of dependency list is present in Netbeans, only per project. And with Netbeans you can also generate a dependency graph by right clicking on your project, and this goes through all dependent projects and their deps as well. I have no deep experience with Eclipse, since I somehow dislike Eclipse with JAVA development, but I think it's available in there somewhere as well. I use those dependencies lists as well to find and clean up dependencies. Cheers, Marco Springer
Re: Error during start of wicket application
The problem may also happen when you have wicket-xyz.jar in the web container's shared folder and additionally in your .war#WEB-INF/lib folder.

Hi, thank you for the answer. I defined Wicket 1.5.3 in the pom.xml. There is no other version defined on my system. Do you have any proposals, where I should check for another version on the system?

Re: Error during start of wicket application
Hi, I suggest you start from a clean Wicket quickstart to see if at least that works. Then, gradually add your components to it until you get the same error.

Re: Error during start of wicket application
You can write a context listener that prints the class path entries (most class loaders are URLClassLoaders) Sent from tablet device. Please excuse typos and brevity.
