bare metal wicket/tomcat HelloWorld example
I'm a wicket newbie and would like to deploy the simple well-known helloworld from wicket-examples but without IDE, ant or maven. What I've done:
web.xml:
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://java.sun.com/xml/ns/j2ee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"
version="2.4">
<display-name>Wicket Examples</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>HelloWorldApplication</param-value>
</init-param>
&l开发者_开发知识库t;/filter>
<filter-mapping>
<filter-name>HelloWorldApplication</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
</web-app>
HelloWorld.html:
<html>
<body>
<span wicket:id="message">Message goes here!</span>
</body>
</html>
HelloWorld.java:
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", "Hello World!"));
}
}
HelloWorldApplication.java:
import org.apache.wicket.protocol.http.WebApplication;
public class HelloWorldApplication extends WebApplication
{
public Class getHomePage()
{
return HelloWorld.class;
}
}
wicket-HelloWorld.war:
WEB-INF/
WEB-INF/web.xml
WEB-INF/classes/
WEB-INF/classes/HelloWorldApplication.class
WEB-INF/classes/HelloWorld.class
WEB-INF/classes/HelloWorld.html
WEB-INF/lib/
WEB-INF/lib/wicket-1.4.15.jar
WEB-INF/lib/slf4j-api.jar
I'm not sure if I need slf4j-api.jar for this simple example
When deployed to tomcat http://localhost:8080/wicket-HelloWorld/ gives:
The requested resource () is not available
What I'm doing wrong?
I've been able to make it work:
1.- I added slf4j-jdk14.jar. Manning Wicket in action bonus chapter 15 was wrong. It tells only to add slf4j-api.jar
2.- wicket-1.4.15.jar MUST BE in WEB-INF/lib. Trying to include it in catalina.properties under shared.loader or $CATALINA_BASE/lib doesn't work for me; despite some webs recommending these places as alternatives to include libraries at runtime.
I've found almost no documentation to build wicket apps using only javac. I think somebody experienced enough should write a little HOW-TO. You're almost forced to use Maven to program even the simplest application in wicket
Regards and thanks to all for the help

It's hard to tell what is wrong with your application. I created a quick sample as follows to test the configuration:
$ mvn archetype:generate
Choosing wicket-archetype-quickstart (189 on my machine), version 1.4.15...
$ mvn tomcat:run
Browsing to http://localhost:8080/wicket and the application works like a charm.
$ mvn package
$ cd target/wicket-1.0-SNAPSHOT/WEB-INF/lib
And these are the libraries required:
- log4j-1.2.14.jar
- slf4j-api-1.5.8.jar
- slf4j-log4j12-1.5.8.jar
- wicket-1.4.15.jar
Sources:
$ cd src/main
$ tree
And my source structure is:
.
|-- java
| `-- com
| `-- blogspot
| `-- nurkiewicz
| |-- HomePage.html
| |-- HomePage.java
| `-- WicketApplication.java
|-- resources
| `-- log4j.properties
`-- webapp
`-- WEB-INF
`-- web.xml
I understand you don't want to use maven (great if you are learning and trying to do anything from scratch), but without any further information I can only advice you to look at my working example above. First of your libraries set seems to be incomplete.
