This article is part of a group of simple, step-by-step tutorials covering common EBIF application development aspects such as two-way communication, creating dynamic content, entering text from remote control, etc.
 
These tutorials assume basic knowledge of EBIF technology and all sample applications were developed and tested using TVWorks XDK, Eclipse IDE and Tomcat Application Server.
 
In this tutorial we'll build a simple EBIF application featuring dynamic content (text and images) which is retrieved from a remote server using the two-way communication. To achieve true interactivity an ETV ecosystem requires a channel between the set-top-box and the outside world, channel which an EBIF application ca use to post and retrieve information through HTTP.
 
After completing this tutorial you'll be able to:
• Understand the two-way request
• Create a new project
• Configure a form and a submit button that sends a string to the server
• Define the xsd schema for the servlet response
• Create the java servlet and deploy it into Tomcat
• Retrieve the servlet response and display the result on the TV screen
• Simulate the application
