+<!--
+	In LAMS 2.3 there was a change in this section in all tools and core parts (central, learning, monitoring etc.)
+	All LAMS web application now use shared application context. See refBeanContext.xml file in lams_common for its description.
+	This refBeanContext.xml contains definition of the shared context. It is located by this entry:
+	<context-param>
+   		<param-name>locatorFactorySelector</param-name>
+   		<param-value>classpath*:/org/lamsfoundation/lams/**/beanRefContext.xml</param-value>
+	</context-param>
+	telling to look for refBeanContext.xml files in selected parts of the classpath.
+	Currently LAMS has only one refBeanContext.xml with one shared context definition.
+	
+	Lams_central uses only beans from the shared context "context.central". That is why there is no value
+	in contextConfigLocation.
+	Even so, this parameter needs to be declared with empty value for locatorFactorySelector to work properly.
+	Also, if no local application context file is declare, there MUST be a file named "applicationContext.xml"
+	in web/WEB-INF containing empty bean list, otherwise there will be errors during start up.
+	If there are local (private for web application; see tools and admin for example) bean definitions,
+	path to application context XML file can still be added to contextConfigLocation.
