<DT>public abstract class <B>MessageResources</B><DT>extends java.lang.Object<DT>implements java.io.Serializable</DL>
<P>
General purpose abstract class that describes an API for retrieving
Locale-sensitive messages from underlying resource locations of an
unspecified design, and optionally utilizing the <code>MessageFormat</code>
class to produce internationalized messages with parametric replacement.
<p>
Calls to <code>getMessage()</code> variants without a <code>Locale</code>
argument are presumed to be requesting a message string in the default
<code>Locale</code> for this JVM.
<p>
Calls to <code>getMessage()</code> with an unknown key, or an unknown
<code>Locale</code> will return <code>null</code> if the
<code>returnNull</code> property is set to <code>true</code>. Otherwise,
a suitable error message will be returned instead.
<p>
<strong>IMPLEMENTATION NOTE</strong> - Classes that extend this class
must be Serializable so that instances may be used in distributable
application server environments.
