cachedrowset

I am investigating using javax.sql.rowset.CachedRowSet in part of my application, however I can only find information on using the proprietary sun implementation com.sun.rowset.CachedRowSetImpl or Oracle specific implementations. The sun implementation is unsupported and subject to change . Using this could also cause problems if I want to deploy to non-Sun virtual machines in the future, and finally it leaves unsuppressible warnings in our build logs which can mask other warnings. Is there an open source alternative implementation that we I can deploy with my application that will work well

Until today I was working with ResultSet when handling results from queries. But today I read a little about RowSet and CachedRowset and I realized they can serve my purposes better. While in all the examples I read where RowSet and CachedRowSet were referred to as object, when I tried it myself in my code I realized those are interfaces and in the examples they use some implementation of those interfaces. Now my question is where do I find those implementations, and is there something official? Do I need to download them or do they come with the JDK? BalusC The implementations are JRE
