-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 that your tomcat-users.xml looks as follows:
-
-       <role rolename="Admin"/>
-       <role rolename="Member"/>
-       <role rolename="Guest"/>
-       <user username="Annie" password="admin" roles="Admin, Member, Guest" />
-       <user username="Diane" password="coder" roles="Member, Guest" />
-       <user username="Ted" password="newbie" roles="Guest" />
-   
-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

Subject: [PATCH 39/59] BAEL-2209 : Quicksort Dionis Prifti (#5365)

* Merged changes from the original repository.

* Added event streaming example with WebFlux.

* Deleted auto-generated code.

* Deleted auto-generated code.

* BAEL-2209 : Added java class and JUnit test for QuickSort implementation.

* Revert "Added event streaming example with WebFlux."

This reverts commit 21527b34643bbb0d1437a0ab3ef392024a391107.

* BAEL-2209: Removed main method from Quicksort class.

* BAEL-2209 : Added the implementation and unit test for 3-Way Quicksort.
