Re: [Springframework-developer] OT: Data Mapping with JavaBeans

[Rob B. <cro...@ya...>]

This may or may not work for you, but here's a
suggestion.

If possible, have the internal generic JavaBeans
implement an interface.  The code which uses these
generic JavaBeans should be coded to the interface so
that various implementations of it can be used.

Then, instead of mapping data from the external
JavaBeans to your generic ones, you implement new
implementations of the generic JavaBeans, which
encapsulate the system-specific ones within them.  The
implementation of the generic JavaBean interface can
then call the appropriate methods of the
system-specific JavaBean to obtain the data they would
need.  

There is no "mapping" where data is read out of one
bean and placed in another, just methods in your
"generic" JavaBeans (which implement the interface)
and make calls to the system-specific JavaBeans for
data.

Just an idea.
