我是 Eclipse、Tomcat 和 Web 服务开发的新手。我只是想学习基础知识。但是，不幸的是，我遇到了一个问题，即使按照互联网上各个链接的说明进行操作，我也无法解决该问题。我尝试过以下方法:
附注:
- 我正在使用 Eclipse Neon 和 apache-tomcat-8.0.36
- 我创建了一个基本的 HelloWorld 示例来检查该项目是否在服务器上运行，并且在同一服务器上运行得非常好
- 当我将 jersey jar 文件(来自 jaxrs-ri/api 和 jaxrs-ri/lib)添加到项目 WEB-INF/lib 并尝试运行为 -> 从 Eclipse 在服务器上运行时，问题就开始了
- 我尝试将项目转换为 Maven 项目，但同样的问题仍然存在
另外，我在服务器上运行项目时发布了错误:

任何帮助将不胜感激。
谢谢!
最佳答案
快速回答:
可能，我在 web.xml 中使用了错误的 servlet 类，这取决于所使用的 Jersey 存档版本。我使用的是 Jersey 2.x，web.xml 具有以下 servlet url，这导致了错误:
<servlet>
<servlet-name>Jersey Web Application</servlet-name>
<servlet-class>com.sun.jersey.spi.container.servlet.ServletContainer</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
然后我将上面的内容替换为以下内容，解决了错误:
<servlet>
<servlet-name>Jersey Web Application</servlet-name>
<servlet-class>org.glassfish.jersey.servlet.ServletContainer</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
关于maven - 严重: A child container failed during start java. util.concurrent.ExecutionException : org. apache.catalina.LifecycleException，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/38568988/
