or is it suffciet it has public accessor methods for the instances.

i have one more question,
talking only about cmp
what are the valid types for cmp fields
1) primitives true or false
2) wrapper - true or false
3) serializable class?? how can this be possible??
does the seializable class have field names corresponing as abstract accessor methods in the bean class.
i aould greatly appreciate if u can give an example of this
thanks

Yes the class should have public fields.
 
It is sorta covered in the JavaRanch Style Guide.
