Evaluating Java System Properties in JSP

gistfile1.txt

Spring context XML:
<!-- expose specific properties to application  -->
<bean id="applicationProperties" class="org.springframework.beans.factory.config.PropertiesFactoryBean">
	<property name="singleton" value="true" />
	<property name="properties">
		<props>
			<prop key="frontleaf.enabled">${frontleaf.enabled}</prop>
			<prop key="frontleaf.streamname">${frontleaf.streamname}</prop>
		</props>
	</property>
</bean>

JSP:
<spring:eval expression="@applicationProperties.getProperty('frontleaf.enabled')"  var="frontleafEnabled" />
<c:if test="${frontleafEnabled}">
	<spring:eval expression="@applicationProperties.getProperty('frontleaf.streamname')"  var="frontleafStreamname" />
<script>
....
</script>
</c:if>
