Error 404-Not Found. No context on this server matched or handled this request., handled

Originally, sae was used properly. As a result, the application deployed the next day suddenly got worse. Various Error 404-Not Found. No context on this server matched or handled this request.

This was the same mistake that I had been tossing for a whole afternoon. I had no choice but to rewrite a program and put it on. The result was still this error. I deleted the application and deleted the jar package without any solution...

Later, I couldn't stand it anymore. I directly clicked on jvm management, stopped, restarted, and stopped. After n times, sae went back to normal again... to prove a problem, the jvm has encountered an exception, so you should consider restarting the jvm repeatedly when appropriate... I am helpless...
