ClassNotFoundException: org.springframework.web.context.ContextLoaderListener


If you ever want to access the Servlet context during startup of your web application spring provides a ContextLoaderListener, that can easily be plugged into web.xml

Some of the most common use cases of ContextLoaderListener are:

1) During startup of the web application, if I want to load some static or configuration data from database and keep in the memory.
2) During startup and before destroy of my web application, If I want to get notify.
3) If I want to have a programatic configuration of spring, instead of from static context file.

You must configure the listner in your web.xml as shown below:

	<listener>
		<listener-class>
        	org.springframework.web.context.ContextLoaderListener
		</listener-class>
	</listener>

And make sure that you have included spring-web.jar dependency in your pom.xml file as shown below:

		<dependency>
			<groupId>org.springframework</groupId>
			<artifactId>spring-web</artifactId>
			<version>3.2.0.RELEASE</version>
		</dependency>

When to use LinkedList or ArrayList?
Accessing elements are faster with ArrayList, because it is index based. But accessing is difficult with LinkedList. It is slow access. This is to access any element, you need to navigate through the elements one by one. But insertion and deletion is much faster with LinkedList, because if you know the node, just change the pointers before or after nodes. Insertion and deletion is slow with ArrayList, this is because, during these operations ArrayList need to adjust the indexes according to deletion or insetion if you are performing on middle indexes. Means, an ArrayList having 10 elements, if you are inserting at index 5, then you need to shift the indexes above 5 to one more.
