在 Eclipse 中的每个“保存”时：org.eclipse.emf.ecore.xmi.FeatureNotFoundException

Question

In my Eclipse Oxygen, I get this error on every save.

From reading around, it seems to come from some version incompatibility in the Servlet standard used but I am not sure what is incompatible with what.

How do I fix this?

An internal error occurred during: "Loading descriptor for project1.". org.eclipse.emf.ecore.xmi.FeatureNotFoundException: Feature 'init-param' not found. (platform:/resource/project1/war/WEB-INF/web.xml, 72, 14)

Here is a screenshot of a similar problem

The problem is that theDTD specified in web.xml , generally specified in the web-app element, does not match the actual structure of the web.xml . The error message points to the line (circled in the screenshot) in the web.xml document which is problematic.

<?xml version = '1.0' encoding = 'UTF-8'?>
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee;http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">

So either

1. remove the DTD ( it is not necessary , but it is helpful to show your incompatibilities)
2. update the web.xml to fit the DTD
3. update the DTD to fit the web.xml
