Question

I’ve just started building my own rest webservice and I started off by going through this excellent tutorial: http://www.vogella.com/articles/REST/article.html#first_project

However there is something that I don’t quite understand. It has to do with the path to the service.

The path is now this for the hello resource:

http://localhost:8080/de.vogella.jersey.first/rest/hello

This is default from the tutorial.

However i would like to change this to a more convenient link, for example like this:

http://localhost:8080/mywebservice/resources/hello

I change the web.xml to the following as a try to achieve it:

<?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="WebApp_ID" version="2.5">
  <display-name>mywebservice</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>de.vogella.jersey.first</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
  </servlet>
  <servlet-mapping>
    <servlet-name>Jersey REST Service</servlet-name>
    <url-pattern>/resources/*</url-pattern>
  </servlet-mapping>
</web-app> 

I changed the display name and the url-pattern but it has no effect. I cant get to the resource using the path I want it to be, though I can retrieve it from the old path.

Why is that? Does the displayname from the web.xml got nothing to do with this?

Answer 1

You are changing the context name of the Webapp. If you’re deploying it in the form of a war (webapp archive), the name of the war would be the context name.

In the example you’re following, you’re creating a Dynamic Web project with that name. You’ll have to rename it suitably.
