Resource not available problem - eclipse

Question

I get a HTTP Status 404 - Requested resource (/Fun/hello) is not available.
I am running Tomcat 7.0, Jersey 1.8, Java 1.6, Eclipse Helios 2.
I am working from a tutorial by Lars Vogel.
As far as I can tell, the resource is being loaded:
INFO: Root resource classes found:
class bighello.Hello
web.xml
<web-app version="3.0" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">
<display-name>Fun</display-name>
<servlet>
<servlet-name>Jersey REST Service</servlet-name>
<servlet-class>com.sun.jersey.spi.container.servlet.ServletContainer</servlet-class>
<init-param>
<param-name>com.sun.jersey.config.property.packages</param-name>
<param-value>bighello</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>Jersey REST Service</servlet-name>
<url-pattern>/rest/*</url-pattern>
</servlet-mapping>
</web-app>
Any ideas?

Answer 1

In the web.xml , you only map one URL pattern , which is /rest/* to call the servlet.
But now , your request URL is /Fun/hello , which does not match any URL patterns you defined in the web.xml , so it returns HTTP Status 404
In fact, refer to section 3.4 of your mentioned tutorial , you should test your REST service under: http://localhost:8080/de.vogella.jersey.first/rest/hello.
