<title>The Resources Component
</properties>
<body>
<section name="Introduction">
<p>The Resources element represents the web
application static resources</em>, from which classes will be loaded,
HTML, JSP and the other static files will be served. This allows the webapp
to reside on various mediums other than the filesystem, like compressed
in a WAR file, in a JDBC database, or in a more advanced versioning
repository.</p>
<p>A unified caching engine is provided for all accesses to the webapp
resources made by the servlet container and web applications which use the
container provided mechanisms to access such resources, such as class laoder
access, access through the <code>ServletContext interface, or native
access through the <code>DirectoryContext interface.
<p>Note: Running a webapp with non-filesystem based
Resources implementations is only possible when the webapp does not
rely on direct filesystem access to its own resources, and uses the methods
in the ServletContext interface to access them.</strong>
<p>A Resources element MAY be nested inside a
<a href="context.html">Context component. If it is not included,
a default filesystem based Resources will be created automatically,
which is sufficient for most requirements.</p>
</section>
<section name="Attributes">
<subsection name="Common Attributes">
<p>All implementations of Resources
support the following attributes:</p>
<attributes>
<attribute name="className" required="false">
<p>Java class name of the implementation to use. This class must
implement the <code>javax.naming.directory.DirContext interface.
It is recommended for optimal functionality and performance,
but not mandatory, that the class extend
<code>org.apache.naming.resources.BaseDirContext, as well as
use the special object types provided in the
<code>org.apache.naming.resources for returned objects.
If not specified, the standard value (defined below) will be used.</p>
</attribute>
</attributes>
</subsection>
<subsection name="Standard Implementation">
<p>The standard implementation of Resources is
<strong>org.apache.naming.resources.FileDirContext, and
is configured by its parent Context element.</p>
</subsection>
</section>
<section name="Nested Components">
<p>No components may be nested inside a Resources element.
</section>
<section name="Special Features">
<p>No special features are associated with a Resources
element.</p>
