Dhruv,
My guess is that you have a bit of work to do.
Here is how I'd attack it.
Start by forgetting the HashMap for a moment. Create java classes an mapping.xml
to handle a regular multi-occuring list of complex objects.
Then, layer the hash3.zip solution on top of the above.
Use one of the fields in your complex object as the key.
Perhaps contatenate multiple (or all) fields to get a key, like x.getLastName() +
x.getPostalCode() ...
To understand better, it would help me to see the client code that would use the
castor objects.
Also, Keith normally has good suggestions for this kind of thing. Keith?
