Hi
I am Nagesh 
The same problem occured to me just a few days back when i was
developing a site with this feature.
The solution is 
1.Download a jar file from jspsmart.com
2.Put the jar file to the lib dir of ur server or somewhere in the
classpath
3.Import the package into ur class with an import statement.
4.Refer the documentation that comes with the jar file and code
accordingly using their classes .

The contents of the jar also contains a webapplication ie a folder with
all relevent files and some examples.
The examples are self explinatory and easy to understand.
Try them it is working fine for me.
