Eclipse turns off English spell checking and XML validation
To solve the problem, the servlet can run, but the XML file is red
Mode 1:
Windows–> Preferences–> XML –> XML Files –> Validate
Find validate and uncheck build
Mode 2:
Windows–> Preferences–> XML(Wild Web Developer)-> Validate& Resolution
Cancel enable validate
Or change both enable namespaces validate and enable schema based} validate to never
Then click apply and it will be OK
The first one, I don’t know whether it’s my eclipse version or something. I didn’t find that one. The second one can solve this problem. I hope it can help you!!
