I suggest to start with http://wicket.apache.org/start/quickstart.html.
This makes your first steps much easier.

Sandor

Hi Andrea,
Am facing issues in running my first application in wicket using tomcat .
Please find the information below.
a. I have drafted three files HelloWorld.java , HelloWorldApplication.java
, HelloWorld.html
as below.
*HelloWorld.java:*
package HelloWorld;
import org.apache.wicket.markup.html.WebPage;
import org.apache.wicket.markup.html.basic.Label;
public class HelloWorld extends WebPage {
public HelloWorld() {
add(new Label("message", "HelloWorld"));
}
}
*HelloWorldApplication.java*
package HelloWorld;
import org.apache.wicket.Page;
import org.apache.wicket.protocol.http.WebApplication;
public class HelloWorldApplication extends WebApplication {
public Class getHomePage() {
return HelloWorld.class;
} }
*HelloWorld.html*
<html>
<body>
<span wicket:id="message" id="message" />
</body>
</html>
*web.xml*
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="
http://java.sun.com/xml/ns/javaee" xmlns:web="
http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="
http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="HelloWorldWicket"
version="2.5">
<display-name>HelloWorldWicket</display-name>
<filter>
<filter-name>HelloWorldApplication</filter-name>
<filter-class>org.apache.wicket.protocol.http.WicketFilter</filter-class>
<init-param>
<param-name>applicationClassName</param-name>
<param-value>HelloWorld.HelloWorldApplication</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>HelloWorldApplication</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
</web-app>
b. Then i have sucessfully complied the java files using javac
HelloWorld.java and javac HelloWorldApplication and created the .class files
Then i have copied this two class files HelloWorld.class and
HelloWorldApplication.class to the tomcat path
/home/kumar/javaapplications/tomcat/apache-tomcat-6.0.36/webapps/ROOT/WEB-INF/classes/HelloWorld/
and placed the web.xml file in WEB-INF path,HelloWorld.html file in ROOT
directory.
After that i have started the tomcat server and launched
http:/localhost:8080/HelloWorld.html , empty page came. So tried with
http:/localhost:8080/HelloWorld/ ---> the 404 error comes up.
I need your help how could i run my first wicket application in tomcat
(amnot using eclipse , maven) with this asusual servlet process.
Please help me ,am waiting for your reply.

Hi,
this kind of questions should be posted to the users list and not the
dev one. Anyway, I think you should add to your classpath also the
current directory "."
Please consider also to use Maven instead of directly compiling with
javac. It saves you a lot of work.
