hi all
I need to get dynamically the value of the primary key of some pojos.
The problem is that i do not know the name of the primary key (or I need a generic methods for doing that)
I wonder if exist i dynamic way of getting it.
regards

you can use <id> for getting the primary key

I surgest you make a Domain object that extends all of your data objects (pojos) and make a getPK() method in each of the Domain objects that calls the correct method in your pojo for the PK. you will obviously have to identiy this method by hand for each obecjt. the advantage of doing it this way is all the effort is done before run time so will be much faster than any magical way of reflecting the PK or something.
