Tomcat 7 ClassNotFoundException：org.glassfish.jersey.servlet.ServletContainer

Question

我試圖在OS X 10.10上使用Jersey 2.13，JDK 8從apache 7.0.57運行RESTful服務。我已經部署了Apache，它啟動正常。 我編寫了一個簡單的RESTful服務並將其部署到WEB-INF / classes。 已配置web.xml。 但是，當我嘗試啟動tomcat時出現以下錯誤的restful資源錯誤

SEVERE: Servlet /resttest threw load() exception
java.lang.ClassNotFoundException:

web.xml中

   <servlet-mapping>
     <servlet-name>Jersey REST Service</servlet-name>
     <url-pattern>/rest/*</url-pattern>
   </servlet-mapping>
</web-app>

java類

 package org.sample.resources; import javax.ws.rs.Path; import javax.ws.rs.GET; import javax.ws.rs.Produces; import javax.ws.rs.core.MediaType; @Path("/xyz") public class TestGet { @GET @Produces(MediaType.TEXT_PLAIN) public String sayHello() { return "Hello Jersey"; } } 

我甚至已經將jersey-container-servlet-core.jar的內容提取到WEB-INF / classes目錄中，但是在重啟時我仍然得到相同的錯誤。

有什么指針嗎？

Answer 1

在Explorer中手動將所有Jersey jar文件復制到WEB-INF / lib; 當我遇到同樣的問題並且對我有用時，我這樣做了。
