When we used eclipse to create a Web project for the MAVEN structure, we chose the artifact ID as Maven-artchetype-webapp, because this catalog is older, The servlet is still 2.3, and it's usually at least 2.5, and cannot change version of project facet when you modify Dynamic Web Module 2.5 in Project facets Dynamic Web module to 2.5, as shown in figure:

Actually on the right you can see the conditions to change to 2.5 and the facets of conflict, the steps to resolve this problem are as follows:

1. Change the servlet to 2.5, open the web.xml of the project and change it before:

[HTML] view plain copy print? <! DOCTYPE Web-app Public "-//sun Microsystems, INC.//DTD Web Application 2.3//en" "Http://java.sun.com/dtd/web-app_2_3 . DTD > <web-app> <display-name>archetype Created Web application</display-name> </web- App>

After the change:

[HTML] view plain copy print?       <?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 "> <display-name>archetype Created Web Application </display-name> </web-app>

2. Modify the project settings and open the project under Navigator. Org.eclipse.jdt.core.prefs under the Settings directory
