Is it possible to create java restful web service based on joins on multiple tables?

I am trying to create a set of restful webservice in java using netbeans and mysql database. Netbeans allows creation of webservice on top of tables and views. I want to create a webservice based on joins on multiple tables along with where clause with conditions based on web service parameters.

My questions are:

1. is this possible?
2. what are different alternatives and the best possible way to achieve this?
3. are there any samples available?
