Generate QJML from Java Bean class...

Quick tool by IBM is a very useful tool for creating parsing logic for conversion from XML to java.

Have a look at the following link...

http://www.ibm.com/developerworks/library/x-quick/index.html

But this converts from DTD -> QJML -> Java.

I have eliminiated the need for creating DTD.
You can create QJML directly from java Bean class if you have.
Just provide the java class and it will generate 90% code for QJML.
You can use it with minor tweeking...
