我在Tomcat 7.0上试过了，效果很好：
package de.jay.jersey.first;import javax.ws.rs.GET;import javax.ws.rs.Path;import javax.ws.rs.Produces;import javax.ws.rs.core.MediaType;@Path("/hello")public class HelloWorldResource {// This method is called if TEXT_PLAIN is request @GET @Produces(MediaType.TEXT_PLAIN) public String sayPlainTextHello() { return "Hello Jersey"; }// This method is called if XML is request @GET @Produces(MediaType.TEXT_XML) public String sayXMLHello() { return "<?xml version="1.0"?>" + "<hello> Hello Jersey" + "</hello>"; }// This method is called if HTML is request @GET @Produces(MediaType.TEXT_HTML) public String sayHtmlHello() { return "<html> " + "<title>" + "Hello Jersey" + "</title>" + "<body><h1>" + "Hello Jersey" + "</body></h1>" + "</html> "; }}web.xml
<?xml version="1.0" encoding="UTF-8"?><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>RestExample</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.jay.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>/rest/*</url-pattern> </servlet-mapping></web-app>
浏览到http：// localhost：8084 / RestExample / rest /
hello，它可以正常运行
