    The description in the header of the web-app looks like an old version and a mess.

    web-app_2_5.xsd
    web-app_3_0.xsd
    Is mixed with.

    If it is a recent version, it will look like the following.

    <web-app xmlns = "http://xmlns.jcp.org/xml/ns/javaee"
      xmlns: xsi = "http://www.w3.org/2001/XMLSchema-instance"
      xsi: schemaLocation = "http://xmlns.jcp.org/xml/ns/javaee
                          http://xmlns.jcp.org/xml/ns/javaee/web-app_4_0.xsd "
      version = "4.0">
