Welcome to StackOverflow. You can format source code with the "101010" toolbar button. I've done it for you this time. — Álvaro González

Your question is pretty vague. Normally don't use a JSP at all to "get" JSON. A smart guy would just have printed the above string as-is. So there must be more into the story. What exactly is the functional requirement? Where does the data come from? Where should the data go? Who should request the data? What are the business conditions? It now much sounds like you're using/choosing the wrong tools for the job. — BalusC

You can use different libraries to convert from diferent java objects to JSON

For example the library json-simple http://code.google.com/p/json-simple/

In the json-simple page you can see some examples of encoding,decoding, and JSP & AJAX with these library.

Structure a Java object in a similar fashion and then use a serialization mechanism such as json-simple or xstream with Json Driver

for instance new XStream(new JettisonMappedXmlDriver()); xstream.toXML(object);
