      This is the XML Schema for the Servlet 2.5 deployment descriptor. 
The deployment descriptor must be named "WEB-INF/web.xml" in the 
web application's war file.  All Servlet deployment descriptors 
must indicate the web application schema by using the Java EE 
namespace: 
http://java.sun.com/xml/ns/javaee 
and by indicating the version of the schema by 
using the version element as shown below: 
    <web-app xmlns="http://java.sun.com/xml/ns/javaee" 
      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
      xsi:schemaLocation="..." 
      version="2.5"> 
      ... 
    </web-app> 
The instance documents may indicate the published version of 
the schema using the xsi:schemaLocation attribute for Java EE 
namespace with the following location: 
http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd

            The following conventions apply to all Java EE deployment
            descriptor elements unless indicated otherwise. - In
            elements that specify a pathname to a file within the same
            JAR file, relative filenames (i.e., those not starting with
            "/") are considered relative to the root of the JAR file's
            namespace. Absolute filenames (i.e., those starting with
            "/") also specify names in the root of the JAR file's
            namespace. In general, relative names are preferred. The
            exception is .war files where absolute names are preferred
            for consistency with the Servlet API.

                The web-app element is the root of the deployment
                descriptor for a web application. Note that the
                sub-elements of this element can be in the arbitrary
                order. Because of that, the multiplicity of the elements
                of distributable, session-config, welcome-file-list,
                jsp-config, login-config, and
                locale-encoding-mapping-list was changed from "?" to "*"
                in this schema. However, the deployment descriptor
                instance file must not contain multiple elements of
                session-config, jsp-config, and login-config. When there
                are multiple elements of welcome-file-list or
                locale-encoding-mapping-list, the container must
                concatenate the element contents. The multiple occurence
                of the element distributable is redundant and the
                container treats that case exactly in the same way when
                there is only one distributable.
