wicket Exception starting filter wicket
eclipse, jakarta-ee, tomcat, wicket
Solution
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)
Problem
I'm trying to create a web application using wicket. These are the steps I've followed : 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 I imported the project to eclipse - I enabled Maven Dependancies with right click - I converted my project to a web project and set a Tomcat 7 server - 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 java.lang.ClassNotFoundException: org.apache.wicket.protocol.http.WicketFilter at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1713) at org.apache.catalina.loader.WebappClassLoader.loadClass(WebappClassLoader.java:1558) at org.apache.catalina.core.DefaultInstanceManager.loadClass(DefaultInstanceManager.java:527) at org.apache.catalina.core.DefaultInstanceManager.loadClassMaybePrivileged(DefaultInstanceManager.java:509) at org.apache.catalina.core.DefaultInstanceManager.newInstance(DefaultInstanceManager.java:137) at org.apache.catalina.core.ApplicationFilterConfig.getFilter(ApplicationFilterConfig.java:260) at org.apache.catalina.core.ApplicationFilterConfig.<init>(ApplicationFilterConfig.java:107) at org.apache.catalina.core.StandardContext.filterStart(StandardContext.java:4656) at org.apache.catalina.core.StandardContext.startInternal(StandardContext.java:5309) at org.apache.catalina.util.LifecycleBase.start(LifecycleBase.java:150) at org.apache.catalina.core.ContainerBase$StartChild.call(ContainerBase.java:1559) at org.apache.catalina.core.ContainerBase$StartChild.call(ContainerBase.java:1549) at java.util.concurrent.FutureTask$Sync.innerRun(FutureTask.java:334) at java.util.concurrent.FutureTask.run(FutureTask.java:166) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1145) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:615) at java.lang.Thread.run(Thread.java:722) ``` Now here is my pom.xml : http://maven.apache.org/maven-v4_0_0.xsd"> 4.0.0 com.amadeus RDA_2 war 1.0-SNAPSHOT quickstart ``` <licenses> <license> <name>The Apache Software License, Version 2.0</name> <url>http://www.apache.org/licenses/LICENSE-2.0.txt</url> <distribution>repo</distribution> </license> </licenses> <properties> <wicket.version>6.6.0</wicket.version> <jetty.version>7.6.3.v20120416</jetty.version> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> </properties> <dependencies> <!-- WICKET DEPENDENCIES --> <!-- <dependency> <groupId>org.apache.wicket</groupId> <artifactId>wicket-core</artifactId> <version>${wicket.version}</version> </dependency> OPTIONAL DEPENDENCY <dependency> <groupId>org.apache.wicket</groupId> <artifactId>wicket-extensions</artifactId> <version>${wicket.version}</version> </dependency> --> <dependency> <groupId>org.apache.wicket</groupId> <artifactId>wicket-core</artifactId> <version>${wicket.version}</version> </dependency> <dependency> <groupId>org.apache.wicket</groupId> <artifactId>wicket-extensions</artifactId> <version>${wicket.version}</version> </dependency> <dependency> <groupId>org.apache.wicket</groupId> <artifactId>wicket-devutils</artifactId> <version>${wicket.version}</version> </dependency> <!-- LOGGING DEPENDENCIES -
