I have created a new web project to practice. After web.xml has written the configuration, visit servlet.
500 errors were reported the first time you visited servlet, and 404 errors were reported the second time.
first time:
:
web.xml:
ask the great god what this is all about.
first of all: 500-internal server error; 404-could not find resources; the first visit may directly cause your project to collapse, so the second visit is 404; furthermore, is your training project framework integration or servlet+jsp? I feel like there's something wrong with your web.xml. That's all I know so far. I hope I can help you.
