Tomcat未能部署.war [英] Tomcat failing to deploy .war

问题描述

我正在尝试关注这个教程创建一个简单的REST Web服务，但是我可以在tomcat上部署它并抛出异常：

I'm trying to follow this tutorial on creating a simple REST web service, however I get to deploying it on tomcat and it throws an exception:

FAIL - Application at context path /restful could not be started
FAIL - Encountered exception org.apache.catalina.LifecycleException: Failed to start component [StandardEngine[Catalina].StandardHost[localhost].StandardContext[/restful]]

我一直在寻找解决方案并找到了这个问题和这个一个他们让我觉得这是一个servlet映射问题但是我不确定如何修复它！

I've looked around for a solution and found this question and this one and they make me think that it's a servlet-mapping problem however I'm not sure how to fix it!

这是我的日志文件：

这是我的web.xml文件：

here is my web.xml file:

<?xml version="1.0" encoding="UTF-8"?>
<web-app
    xmlns="http://java.sun.com/xml/ns/javaee" version="3.0"
    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">

  <servlet>
    <servlet-name>RestfulContainer</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>com.mcnz.ws</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
  </servlet>

  <servlet-mapping>
    <servlet-name>RestfulContainer</servlet-name>
    <url-pattern>/resources/*</url-pattern>
  </servlet-mapping>    

</web-app>

并且冒着给你太多信息的风险，这里是我的文件夹结构的ls ：

and at the risk of giving you all far too much information, here is a ls of my folder structure:

./WEB-INF:

推荐答案

正如上面的注释所示，问题结果是应用程序web.xml在servlet定义中引用了一个java类。通过确保应用程序实际包含该类来纠正问题。找到丢失的jar文件并将其放在WEB-INF / lib目录中。

As the above comment shows, the problem turned out to be that the application web.xml referenced a java class in a servlet definition. The problem was corrected by making sure the application actually contained that class. The missing jar file was located and put in the WEB-INF/lib directory.
