wicket Exception starting filter wicket

votes

I'm trying to create a web application using wicket. These are the steps I've followed :

  1. I created a maven project using this command :

    mvn archetype:generate -DarchetypeGroupId=org.apache.wicket -DarchetypeArtifactId=wicket-archetype-quickstart -DarchetypeVersion=6.6.0 -DgroupId=com.mycompany -DartifactId=myproject -DarchetypeRepository=https://repository.apache.org/ -DinteractiveMode=false

  2. I imported the project to eclipse

  3. I enabled Maven Dependancies with right click
  4. I converted my project to a web project and set a Tomcat 7 server
  5. By right click I ran the project on this server, producing the message: HTTP Status 404 - The requested resource is not available.

This the error message on the console :

SEVERE: Exception starting filter wicket.myproject

<filter-mapping>

Can anyone help me please ????

try running mvn install, refresh the workspace, then run tomcat again. sometimes, with some versions of m2e, Eclipse doesn't get the jars until you run the build manually. - tetsuo
See my comment on the answer below. Try running without eclipse in the way, you might be better of ditching eclipse all together ;) - bert
@tetsuo After running mvn install i have this error from JUnit : wicket.Initializer cannot be cast to org.apache.wicket.IInitializer - enzo

A bit late, but here is what solved the problem:

Right click on project -> Properties -> Deployment Assembly

Be sure that the libraries of the project are deployed into the WEB-INF/lib folder. In my case there were no libraries at all, so I had to add them by pressing

Add -> Java Build Path Entries

And selecting the libraries (wicket libraries among those)

Did you change your POM? This class belongs to wicket-core, the quickstart added this:

<dependency>
  <groupId>org.apache.wicket</groupId>
  <artifactId>wicket-core</artifactId>
  <version>6.6.0</version>
</dependency>

Check that this declaration is in your pom.xml.
