Are you running the .java file on the server?If you do so,you will get this error.You only need to run the .jsp(or .html) file on the server,and even if your .jsp(or .html) file include some .java file's methods.The browser can only run .html(or .jsp) files.

在服务器上运行.java文件吗?如果这样做，就会得到这个错误。您只需在服务器上运行.jsp(或.html)文件，即使.jsp(或.html)文件包含一些.java文件的方法。浏览器只能运行.html(或.jsp)文件。

The servlet mapping is *.do only mapped resources by extension. The message

servlet映射是*。只按扩展名映射资源。的消息

The requested resource () is not available

shows that resource path is empty. The requested resource is web application root.

显示资源路径为空。所请求的资源是web应用程序根。

Even if you have welcome file index.jsp it might not be loaded by the Tomacat. It might also doesn't exist.

即使您有欢迎文件索引。jsp可能不会被Tomacat加载。它也可能不存在。

If you are using Struts framework you should not access JSP directly, and to access Struts action you should specify valid URL that is mapped to the action. I.e. http://localhost:8080/StrutsExample1/helloworld.do.

如果您正在使用Struts框架，那么您不应该直接访问JSP，并且要访问Struts操作，您应该指定映射到该操作的有效URL。例如http://localhost:8080 / StrutsExample1 / helloworld.do。
