问题描述

我在此 http://www.ibm.com中遵循确切的步骤/developerworks/library/wa-aj-tomcat/，我正确地放入了所有罐子(我相信).而且我仍然收到类似以下的错误:

I follow exact steps in this http://www.ibm.com/developerworks/library/wa-aj-tomcat/, and I included all the jars correctly(i believe). And I still got the errors like the following:

我只是第一步，打个招呼.我的web.xml和Java文件如下:

I just did the first step, show hello. My web.xml and java file are the following:

package sample.hello.resources;

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 HelloResource {
    @GET
    @Produces(MediaType.TEXT_PLAIN)
    public String sayHello() {
        return "Hello Jersey";
    }
}

web.xml 

<?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>Jersey</display-name>
  <welcome-file-list>
    <welcome-file>index.html</welcome-file>
  </welcome-file-list>

  <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>sample.hello.resources</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>

我已经搜索了一段时间，找不到很好的解决方案. 顺便说一句，我的jar文件列表是: activation.jar asm-3.1.jar com.sun.jersey.jersey-server-1.4.0.jar jaxb-api-2.2.5.jar jaxb-impl-2.2_1.jar jersey-client.jar jersey-core.jar jersey-json-1.7.jar jersey-spring-1.11-b02.jar jsr311-api.1.1.1.jar stax-api.jar wstx-asl.jar

I have been googling for a while, I couldn't find a good solution. btw, my jar file list is: activation.jar asm-3.1.jar com.sun.jersey.jersey-server-1.4.0.jar jaxb-api-2.2.5.jar jaxb-impl-2.2_1.jar jersey-client.jar jersey-core.jar jersey-json-1.7.jar jersey-spring-1.11-b02.jar jsr311-api.1.1.1.jar stax-api.jar wstx-asl.jar

建议在网络上使用这些罐子.我直接将它们复制到WEB-INF/lib文件夹中.我担心的一件事是路径问题，有人告诉我之前我应该​​通过右键单击类project-> build path然后添加jars添加一些jar.我也尝试过，不是一个好消息.我正在运行Tomcat7.0.网络也会运行到错误报告页面.请帮忙！

these jars are recommended on the web. I copied them directly to the WEB-INF/lib folder. One thing I'm worry about is the path issue, someone shown me before that I should add some jars by right click the class project->build path and then add jars. I tried it as well, not good news. I'm running Tomcat7.0. The web runs to a error report page as well.Please help!

我尝试了两个本地主机链接:8080/Jersey/WEB-INF/web.xml& 8080/Jersey/rest/hello.都失败了！

I tried two local host link: 8080/Jersey/WEB-INF/web.xml & 8080/Jersey/rest/hello. both fail!

先谢谢了.

推荐答案

我怀疑这可能是StackOverflow上另一个问题的重复. Jersey当jersey-json时，不存在WebApplication提供程序添加依赖项

I suspect this may be a duplicate of another question on StackOverflow. Jersey No WebApplication provider is present when jersey-json dependency added

最后，确保jersey-server是对您的类路径的依赖. 当您说您的jar文件列表"时，您确定这些jar位于Web应用程序的类路径中吗?这可能是导致您出现问题的IDE构建路径的函数.

Ultimately, make sure that jersey-server is a dependency on your classpath. When you say "your jar file list", are you certain that these jars are in the web application's classpath? It may be a function of your IDE's build path that is causing your problems.

如果仍然有问题，请包括您使用的IDE以及类路径的配置方式.

If you still have issues, please include the IDE you use, along with how your classpath is configured.
