Answer 1

If you want to use version 3.1 you need to use the following schema:

• http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd

Note that 3.0 and 3.1 are different: in 3.1 there's no Sun mentioned, so simply changing 3_0.xsd to 3_1.xsd won't work.

This is how it should look like:

Also, make sure you're depending on the latest versions in your pom.xml. That is,

    org.apache.maven.plugins
    maven-war-plugin
    2.6
    
        ...
    

and

    javax.servlet
    javax.servlet-api
    3.1.0
    provided

Finally, you should compile with Java 7 or 8:

    org.apache.maven.plugins
    maven-compiler-plugin
    3.3
    
        1.7
        1.7
