It turns out that for the "enrollDay" field , the "PropertyDescriptor " can NOT find its write method. For the rest of fields, it has no problem in terms of converting the string inot int, etc. So is it true that , in order to make this work, you can only do straightford setter method without any twisting around it ?

Can you be more specific about the problem you are having? Also a real compilable example would help demonstrate the problem.

Is the problem because you have a different return type for the getter than you have parameter for the setter (can't tell, you conveniently left off the return types for your methods)?

The method pair for a property, of type T must be:

It does not matter what the value is stored as in the bean - the Introspector uses methods to determine Bean properties. My guess is that you messed up one of the method signatures. You can get around this requirement (I think) by writing your own BeanInfo class which knows what methods to call...
