"Error 404--Not Found" error handling method (403 error can be solved)

Error 404--Not Found
From RFC 2068 Hypertext Transfer Protocol -- HTTP/1.1:
10.4.5 404 Not Found
The server has not found anything matching the Request-URI. No indication is given of whether the condition is temporary or permanent.

If the server does not wish to make this information Available to the client, the status code 403 (Forbidden) can be used instead. The 410 (Gone) status code SHOULD be used if the server knows, through some internal configurable mechanism, that an old resource is permanently unavailable and has no forwarding address .

403 Error screenshots are as follows:

A lot of people have nothing to do with this. After my research, the solution is as follows:

Find the folder where the server is located, ie startWeblogic.cmd The folder where it is located, and the domain under which the service is located. Find the myserver folder and delete it directly (this folder is the folder that is automatically generated when the server is started. There is a related log file). Turn off the corresponding service before deleting. Otherwise the myserver folder cannot be deleted.
