1. Web application is not deployed
2. URL input error
Troubleshooting: first, check whether the IP address and port number of the URL are written correctly.
Secondly, check whether the context path is correct. Project ——– properties —– myelipse —– web — Web context root, and check whether the path name is written correctly.
Finally, check that the file name is written correctly.
3. Directory cannot be referenced
Troubleshooting method:

Since the contents under the meta-infweb-inf folder cannot be published to the public, if you refer to files with these two directories, it is definitely not allowed. For example:http://localhost:8080/guestbook/WEB-INF/index.htmlIt’s the wrong file location

The “helloworldservlet” is changed to the name of the file you want to run. This is a summary of these. Of course, there may be more unexpected errors in practical application, which is also normal. If there are any errors, please point out them.
