Hi, Hmkcode!!! I fixed some problems in your project java-servlet-json. This is commit fixs problems with charset. In your original code doesn't work symbol from another language (ukrainian, japanese...). I added new servlet method doGet() and new javascript function getData(), which rebuild list of articles after reloading of page. Because after reloading pages list of articles would clear up. And in pom.xml  we use war not jar archive for web project. I am sorry, for me English. 
P.S: Thank you for your articles. They are very useful!!!
