Web project to solve the Tomcat server: error
The origin server did not find a current representation for the target resource or is not willing to disclose that one exists.
Adjust a lot of configuration parameters, and even the configuration is not effective in web.xml
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
And finally found the original project path configured wrong.
Modification steps:
IDEA Tomcat environment as an example:
Edit Server Configuration
Modify the Startup Path Project
Restart, index.jsp successfully loaded by default.
