	This is the XML Schema for the JBoss AS 7.0 web application deployment descriptor.
	The deployment descriptor must be named "WEB-INF/jboss-web.xml" in
	the WAR file.  All JBoss Web deployment descriptors must indicate
	the JBoss schema by using the Java EE namespace:

        http://www.jboss.com/xml/ns/javaee

	and by indicating the version of the schema using the version element as shown below:

        <jboss-web xmlns="http://www.jboss.com/xml/ns/javaee"
           xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

           version="7.0">

	       ...

        </jboss-web>

	Instance documents may indicate the published version of
	the schema using the xsi:schemaLocation attribute for the
	Java EE namespace with the following location:

      <xsd:documentation> 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

            <![CDATA[

            Clustering only: Determines when the container should consider that a session
            must be replicated across the cluster.
            Possible values are:
               1 - "ACCESS"
               2 - "SET_AND_GET"
               3 - "SET_AND_NON_PRIMITIVE_GET" (default value)
               4 - "SET"

            The rationale for this setting is that after a mutable object stored as a session attribute
            is accessed from the session, in the absence of a setAttribute call the container has no
            clear way to know if the object (and hence the session state) has been modified.

            In all cases, calling setAttribute marks the session as needing replication.

            ACCESS - merely accessing the session marks the session as dirty.

            SET_AND_GET is conservative but not optimal (performance-wise): it will always replicate the
            session even if its content has not been modified but simply accessed.

            SET_AND_NON_PRIMITIVE_GET is conservative but will only replicate if a non-primitive Object
            has been accessed (i.e. the object is not of a well-known immutable JDK type such as Integer,
            Long, String, etc.) This is the default value.

            SET assumes that the developer will explicitly call setAttribute on the session
            if it needs to be replicated. This setting prevents unnecessary replication, but requires very
            good coding practices to ensure setAttribute is always called whenever an attribute value
            is modified.

            Examples:
                  <replication-trigger>SET_AND_GET</replication-trigger>
               or
                  <replication-trigger>SET_AND_NON_PRIMITIVE_GET</replication-trigger>

            Clustering only: Determines the session replication granularity level.
            Possible values are:
                    1 - "SESSION" (default)
                    2 - "ATTRIBUTE"

            The first option indicates that replication is done per session instance, i.e. when
            the session is considered modified, the whole session object will be serialized
            and replicated. This is the preferred policy when the sessions are generally small.

            The second option indicates that replication is performed only for the the dirty
            attributes in the session, plus some session data, like lastAccessTime. For sessions
            carrying large amounts of data, parts of which are infrequently accessed,
            this option can increase replication performance.

            A third option, "FIELD" was available in AS 4.x and AS 5.x, but it
            is not supported by AS 6.

                2 - "ASYNCHRONOUS"

            In SYNCHRONOUS mode, session replication occurs in the same thread that processes a given
            request.  A request will not complete until the associated session is successfully replicated.

            In ASYNCHRONOUS mode, session replication occurs in a separate thread from the one that processes
            a given request.  The request thread only initiates replication, but does not wait for it to complete.

            If not defined, the replication mode defined in the distributed cache configuration will be used.

            Clustering only: Determines the maximum interval between requests, in
            seconds, after which a request will trigger replication of the session's
            timestamp and other metadata regardless of whether the request has otherwise
            made the session dirty.  Such replication ensures that other nodes in the
            cluster are aware of the most recent value for the session's timestamp
            and won't incorrectly expire an unreplicated session upon failover. It also
            results in correct values for HttpSession.getLastAccessedTime() calls
            following failover.

            The cost of this metadata replication depends on the configured
            replication-granularity. With <code>SESSION</code>, the session's
            attribute map is replicated along with the metadata, so it can be fairly
            costly.  With other granularities, the metadata object is replicated
            separately from the attributes and only contains a String, and a few longs,
            ints and booleans.

            A value of 0 means the metadata will be replicated whenever the session is
            accessed.  A value of -1 means the metadata will be replicated only if some
            other activity during the request (e.g. modifying an attribute) has
            resulted in other replication work involving the session. A positive value
            greater than the HttpSession.getMaxInactiveInterval() value will be treated
            as a likely misconfiguration and converted to 0; i.e. replicate the
            metadata on every request.
