運行澤西項目（REST Web服務）到Tomcat

我嘗試按照本指南：tutorial但是當我執行的Web瀏覽器，它返回一個錯誤：運行澤西項目（REST Web服務）到Tomcat

HTTP Status 404 -/
type Status report 
message/
description The requested resource (/rest.api/rest/hello) is not available.

我已經在/ usr安裝tomcat7/local在我的mac上，並在終端上使用startup.sh運行它。這是我的web.xml和Hello.java

<?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_3_0.xsd" id="WebApp_ID" version="3.0"> 
<display-name>HelloRest</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>rest.api</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>

package rest.api; 

import javax.ws.rs.GET; 
import javax.ws.rs.Path; 
import javax.ws.rs.Produces; 
import javax.ws.rs.core.MediaType; 

// POJO, no interface no extends 

// The class registers its methods for the HTTP GET request using the @GET annotation. 
// Using the @Produces annotation, it defines that it can deliver several MIME types, 
// text, XML and HTML. 

// The browser requests per default the HTML MIME type. 

//Sets the path to base URL + /hello 
@Path("/hello") 
public class Hello { 

// 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> "; 
} 

}

這是我的配置項目：

任何建議？

什麼是您的應用程序的上下文根？請求URI的外觀如何？ – 2012-04-10 16:00:44

只需要使用web.xml中

<servlet> 
     <servlet-name>ServletAdaptor</servlet-name> 
     <servlet-class>com.sun.jersey.spi.container.servlet.ServletContainer</servlet-class> 
     <load-on-startup>1</load-on-startup> 
    </servlet> 
    <servlet-mapping> 
     <servlet-name>ServletAdaptor</servlet-name> 
     <url-pattern>/rest/*</url-pattern> 
    </servlet-mapping>

希望這將幫助您進行配置。

試試這個。

<servlet> 
    <servlet-name>jersey-serlvet</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>Your Service Package Name</param-value> 
    </init-param> 
    <init-param> 
     <param-name>com.sun.jersey.api.json.POJOMappingFeature</param-name> 
     <param-value>true</param-value> 
    </init-param> 
    <load-on-startup>1</load-on-startup> 
</servlet> 


<servlet-mapping> 
    <servlet-name>jersey-serlvet</servlet-name> 
    <url-pattern>/rest/*</url-pattern> 
</servlet-mapping>

請參閱POJOMappingFeature初始參數 – 2013-05-30 05:40:05

<servlet-name> jersey-serlvet </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> rest.api </param-value> 

</init-param> 

<init-param> 

    <param-name> com.sun.jersey.api.json.POJOMappingFeature </param-name> 

    <param-value> true </param-value> 

</init-param> 

<load-on-startup>1</load-on-startup>

<servlet-name> jersey-serlvet </servlet-name> 

<url-pattern> /rest/* </url-pattern>

在更新版本的Jersey中，servlet-class和init-param改變了。請嘗試以下操作：

<servlet> 
    <servlet-name>Jersey REST Service</servlet-name> 
    <servlet-class>org.glassfish.jersey.servlet.ServletContainer</servlet-class> 
    <init-param> 
     <param-name>jersey.config.server.provider.packages</param-name> 
     <param-value>Your Service Package Name</param-value> 
    </init-param> 
    <load-on-startup>1</load-on-startup> 
    </servlet>

這對我使用澤西島版本：2.5.1。
