Web application development using Google Web Toolkit

This work includes making of a web portal and web application for content editing using the Google Web Toolkit (GWT). The use of GWT can facilitate the development of Ajax application because we are not required to deal with incompatibility between web browsers. we can be fully dedicated to the web application development in the Java environment. With GWT we can make whole web application in just one language, Java. In principal, dynamic web applications are written in several different languages - with markup language HTML and scripting language JavaScript on client side, which serves to validate and handling Document Object Model (DOM). Unfortunately, with emergence of new and new web browsers, a different interpretation of the JavaScript code from browser to browser began to emerge. Small differences have led to this, that the developers needed to invest more time in adaptation of the web application to operate in all the different browsers, rather than just invest their time in the development. On the server side, where it is possible to develop a web application in different programming languages, with GWT, we develop web applicationjust in Java. The code for the entire web application with GWT is only in one programming language, which simplifies the entire production
