/**
 * This is a cluster safe Quartz/Spring FactoryBean implementation, which produces a JobDetail implementation that can invoke any no-arg method on any Class.
 * <p>
 * Use this Class instead of the MethodInvokingJobDetailBeanFactory Class provided by Spring when deploying to a web environment like Tomcat.
 * <p>
 * <b>Implementation</b><br>
 * Instead of associating a MethodInvoker with a JobDetail or a Trigger object, like Spring's MethodInvokingJobDetailFactoryBean does, I made the [Stateful]MethodInvokingJob, which is not persisted in the database, create the MethodInvoker when the [Stateful]MethodInvokingJob is created and executed.
 * <p>
 * A method can be invoked one of several ways:
 * <ul>
 * <li>The name of the Class to invoke (targetClass) and the static method to invoke (targetMethod) can be specified.
 * <li>The Object to invoke (targetObject) and the static or instance method to invoke (targetMethod) can be specified (the targetObject must be Serializable when concurrent=="false").
 * <li>The Class and static Method to invoke can be specified in one property (staticMethod). example: staticMethod = "example.ExampleClass.someStaticMethod"
 * <br><b>Note:</b>  An Object[] of method arguments can be specified (arguments), but the Objects must be Serializable if concurrent=="false".
 * </ul>  
 * <p>
 * I wrote MethodInvokingJobDetailFactoryBean, because Spring's MethodInvokingJobDetailFactoryBean does not produce Serializable
 * JobDetail objects, and as a result cannot be deployed into a clustered environment like Tomcat (as is documented within the Class).
 * <p>
 * <b>Example</b>
 * <code>
 * <ul>
 * 	&lt;bean id="<i>exampleTrigger</i>" class="org.springframework.scheduling.quartz.CronTriggerBean"&gt;
 * <ul>
	<i>&lt;!-- Execute example.ExampleImpl.fooBar() at 2am every day --&gt;</i><br>
	&lt;property name="<a href="http://www.opensymphony.com/quartz/api/org/quartz/CronTrigger.html">cronExpression</a>" value="0 0 2 * * ?" /&gt;<br>
	&lt;property name="jobDetail"&gt;
	<ul>
	&lt;bean class="frameworkx.springframework.scheduling.quartz.<b>MethodInvokingJobDetailFactoryBean</b>"&gt;
	<ul>
	&lt;property name="concurrent" value="<i>false</i>"/&gt;<br>
	&lt;property name="targetClass" value="<i>example.ExampleImpl</i>" /&gt;<br>
	&lt;property name="targetMethod" value="<i>fooBar</i>" /&gt;
	</ul>
	&lt;/bean&gt;
	</ul>
	&lt;/property&gt;
	</ul>
	&lt;/bean&gt;
	<p>
	&lt;bean class="org.springframework.scheduling.quartz.SchedulerFactoryBean"&gt;
	<ul>
	&lt;property name="triggers"&gt;
	<ul>
	&lt;list&gt;
	<ul>
	&lt;ref bean="<i>exampleTrigger</i>" /&gt;
	</ul>
	&lt;/list&gt;
	</ul>
	&lt;/property&gt;
	</ul>
	&lt;/bean&gt;
	</ul>
 * </code>
 * In this example we created a MethodInvokingJobDetailFactoryBean, which will produce a JobDetail Object with the jobClass property set to StatefulMethodInvokingJob.class (concurrent=="false"; Set to MethodInvokingJob.class when concurrent=="true"), which will in turn invoke the static <code>fooBar</code>() method of the "<code>example.ExampleImpl</code>" Class. The Scheduler is the heart of the whole operation; without it, nothing will happen.
