从HTML调用REST Web服务

Question

package com.leadwinner;

import javax.ws.rs.GET;  
import javax.ws.rs.POST;
import javax.ws.rs.Path;  
import javax.ws.rs.PathParam;  
import javax.ws.rs.Produces;  
import javax.ws.rs.QueryParam;
import javax.ws.rs.core.MediaType;  

@Path("ServiceProvider2")  
public class ServiceProvider2 {  
 @GET  
 @Path("/InchToFeet")  
  @Produces(MediaType.TEXT_XML)  
  public String convertInchToFeet(@QueryParam("i") int i) {  

    int inch=i;  
    double feet = 0;  
    feet =(double) inch/12;  

    return "<InchToFeetService>"  
    + "<Inch>" + inch + "</Inch>"  
      + "<Feet>" + feet + "</Feet>"  
     + "</InchToFeetService>";  
  }  


}

The following URL returns a result as XML:

.../SampleRest/ServiceProvider2/InchToFeet?i=2

This is fine, though when I am trying to run HTML files using tomcat server, I get the error:

webpage not found 404 html files not running in restful web services using jersey

In order to make html files also work, you should modify the web.xml file to map your Jersey Servlet only to the urls that it should handle (RESTful urls).

<web-app>
    <servlet>
        <servlet-name>MyApplication</servlet-name>
        <servlet-class>org.glassfish.jersey.servlet.ServletContainer</servlet-class>
        <init-param>
            ...
        </init-param>
    </servlet>
    ...
    <servlet-mapping>
        <servlet-name>MyApplication</servlet-name>
        <url-pattern>/ServiceProvider2/*</url-pattern>
    </servlet-mapping>
    ...
</web-app>
