Hi, I am new to J2EE and JBoss. I am attempting to write a simple hello
world example to try and get thing up an running. The problem I am
getting is that I get a message back that says that it can't find the
servlet that I am trying to load.
I have a simple servlet class that prints out "Hello World". The source
to it is as follows:
package net.cordata.HelloWorld.web;
import java.io.IOException;
import javax.servlet.ServletOutputStream;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
public class HelloWorld extends HttpServlet
{
public void doGet(HttpServletRequest req, HttpServletResponse res)
throws IOException, ServletException
{
res.setContentType("text/plain");
ServletOutputStream out = res.getOutputStream();
out.println("Hello World!");
}
}
I have this place in a WAR file under
/WEB-INF/classes/net/cordata/HelloWorld/web, and have the following
web.xml file in my /WEB-INF directory:
<?xml version="1.0" encoding="ISO-8859-1"?>
<!DOCTYPE web-app
PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
"http://java.sun.com/dtd/web-app_2_3.dtd";>
<web-app>
<display-name>Hello World</display-name>
<description>
Testing using hello world to get servlets working,
and to get directory strucuture setup, and to get
template build system.

</context-param>
<servlet>
<servlet-name>HelloWorld</servlet-name>
<servlet-class>net.cordata.HelloWorld.web.HelloWorld</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>HelloWorld</servlet-name>
<url-pattern>/helloworld</url-pattern>
</servlet-mapping>
<session-config>
<session-timeout>30</session-timeout> <!-- 30 minutes -->
</session-config>
</web-app>
Finally I have the WAR file placed in a EAR file which has a
application.xml file in META-INF as follows:
<application>
<display-name>Hello World</display-name>
<description>An example application</description>
<module>
<web>
<web-uri>HelloWorld.war</web-uri>
<context-root>/helloworld</context-root>
</web>
</module>
</application>
The when I load up http://<myhost>:8080/helloworld/helloworld I get a
message stating that it could not find class:
net.cordata.HelloWorld.web.HelloWorld
I have searched everywhere I can think of and tried all sorts of
variations, but no luck. If I am doing something stupid because I am new
at this I would greatly appreciate someone pointing out to me what.
Thanks,
