Using Reflection to implement toString() for beans

I borrowed some reflection code to implement toString() methods for some bean objects. However this resulted in this code being strewn around all over the place. The code which I took was accessing the private fields of the objects, hence couldn't be used either in a superclass or couldn't be extracted as a method in a util class. I then thought it might be  a better idea to access the public methods instead, and now I have all the code in one class. All you need to do is put a call to the method getStringForBean() in your bean's toString() method. Or if you have a class hierarchy, with one base class being the parent for all other bean classes (as it was in my case), then you can put in the base class. I am also putting the old method or code  in getStringForObject() method. If your class doesn not have public accessor methods you can paste this code into the individual classes. 

Please let me know if you have any comments or suggestions
