简单的Hello World Servlet在Eclipse Tomcat中给出错误404

Question

I am trying to follow a very simple Hello World servlet tutorial from this link . I have followed all steps as written, but when I run it on the tomcat7 server (downloaded from within eclipse), it gives me an HTTP error 404, saying that the requested source is not available.

Note that my server is working fine on

localhost:8080

. But the servlet -

localhost:8080/HelloWorldServlet/HelloWorld

is giving me this error.

Answer 1

It means Tomcat cannot map your url to existing servlet method. Are you sure, you covered all steps correctly? Hard to say with no details included.

Answer 2

网址后可能缺少应用程序名称，如果将其上传到gitHub，也许我可以提供更多信息。
