+About the application
+---------------------
+This application demonstrates the usage of JavaEE Web Annotations.
+
+
+Contents of the application
+---------------------------
+1. AccountServlet.java - Demonstrates the @WebServlet and @ServletSecurity annotation.
+
+NOTES: @WebServlet annotation designates the AccountServlet class as a Servlet component.
+       The usage of its parameters 'urlPatterns' & 'initParams' can be observed.
+       An initialization parameter 'type' is being set to denote the type of the bank account.
+       
+       @ServletSecurity annotation imposes security constraints on the AccountServlet based on
+       the tomcat-users.xml (this code assumes there is a role 'admin' in your tomcat-users.xml)
+   
+N.B : To see  @ServletSecurity annotation in action, please uncomment the annotation code 
+      for @ServletSecurity.
+      
+      
+2. BankAppServletContextListener.java - Demonstrates the @WebListener annotation for denoting a class as a ServletContextListener.
+   
+NOTES: Sets a Servlet context attribute ATTR_DEFAULT_LANGUAGE to 'english' on web application start up, 
+       which can then be used throughout the application.
+
+
+3. LogInFilter.java - Demonstrates the @WebFilter annotation.
+                      
+NOTES: @WebFilter annotation designates the LogInFilter class as a Filter component.
+       It filters all requests to the bank account servlet and redirects them to
+       the login page.
+       
+N.B : To see @WebFilter annotation in action, please uncomment the annotation code for @WebFilter.
+
+
+4. UploadCustomerDocumentsServlet.java - Demonstrates the @MultipartConfig annotation.
+
+NOTES: @MultipartConfig anotation designates the UploadCustomerDocumentsServlet Servlet component, 
+       to handle multipart/form-data requests.
+       To see it in action, deploy the web application an access the url: http://<your host>:<your port>/JavaEEAnnotationsSample/upload.jsp
+       Once you upload a file from here, it will get uploaded to D:/custDocs (assuming such a folder exists).
+       
+ 
+5. index.jsp - This is the welcome page.
+
+NOTES: You can enter a deposit amount here and click on the 'Deposit' button to see the AccountServlet in action.
+
+6. login.jsp - All requests to the AccountServlet are redirected to this page, if the LogInFilter is imposed.
+
+7. upload.jsp - Demonstrates the usage of handling multipart/form-data requests by the UploadCustomerDocumentsServlet.       
+       
+   
+Building and Running the application
+------------------------------------
+To build the application:
+
+1. Open the project in eclipse
+2. Right click on it in eclispe and choose Run As > Maven build
+3. Give 'clean install' under Goals
+4. This should build the WAR file of the application
+
+To run the application:
+
+1. Right click on the project
+2. Run as > Run on Server
+3. This will start you Tomcat server and deploy the application (Provided that you have configured Tomcat in your eclipse)
+4. You should now be able to access the url : http://<your host>:<your port>/JavaEEAnnotationsSample
