提问by FenchelT
First of all this is my first post here so if I do something wrong pls. be so kind to let me know. It is also my first touch with developing webservices in Java. As I haven't found an answer whilst using the search function I have to ask you for an idea.
首先，这是我在这里的第一篇文章，所以如果我做错了什么，请。请让我知道。这也是我第一次接触用 Java 开发网络服务。由于我在使用搜索功能时没有找到答案，所以我必须向您征求意见。
Yesterday I was running a Dynamic Web Project in Eclipse (EE) and everything was working fine. Then, I have created a new Dynamic Web Projecte, have copied some class-files, jar-files and I have created a new web.xml file. After that I can't run the new project and I can't run the project which was working fine yesterday. Here is the output from my console:
昨天我在 Eclipse (EE) 中运行一个动态 Web 项目，一切正常。然后，我创建了一个新的动态 Web 项目，复制了一些类文件、jar 文件，并创建了一个新的 web.xml 文件。之后，我无法运行新项目，也无法运行昨天运行良好的项目。这是我的控制台的输出：

Do you have any ideas?
你有什么想法？
回答by Akhilesh Singh
You have added a servlet in your web.xml file - the error message shows it like this "Servlet mapping specifies an unknown servlet name CW Service" . Look at the web.xml and correctly create servlet, servlet mapping and make sure the class name in servlet section is there in the classpath.
您已在 web.xml 文件中添加了一个 servlet - 错误消息显示为“Servlet 映射指定了一个未知的 servlet 名称 CW 服务”。查看 web.xml 并正确创建 servlet、servlet 映射并确保 servlet 部分中的类名在类路径中。
