Guide on integrating AJAX with servlets and JSP for database-driven applications

What is the best way to integrate AJAX technology with servlets and JSP for a database application? I am currently developing a JSP page that makes calls to JavaScript. The JavaScript then calls a servlet where the database is accessed. How can I pass the data back from the servlet?

Answer №1

The information is typically sent back to the browser in different formats:

  • HTML code that includes both presentation and data, achieved by redirecting to a JSP page.
  • XML format containing only data, created in the servlet (using tools like JAXB) and then transmitted through the response writer.
  • JSON format with just data, produced in the servlet (making use of libraries such as GSON) and sent using the response writer.

JavaScript has the capability to process all three types of data and modify the content shown on the screen accordingly.
