Rick Hillegas commented on DERBY-942:
-------------------------------------

Hi Anurag,

Thanks for the explanation. I have upgraded to mustang build 76 and that indeed fixed the
TestQueryObject problem.

Since the other test is broken, it sounds like this patch is not ready to commit. When you
are ready, please say in your submission comment that the patch is ready for committing and
not just reviewing. Thanks!

> As described in the JDBC 4 spec, sections 20.1, 20.2, and 3.1.
> The Ease of Development extensions provide a way to create tabular DataSets from queries
and tuple signatures. The jdk ships with a factory for creating these DataSets, which is a
class which implements the QueryObjectGenerator interface. A database can write its own custom
QueryObjectGenerator, or just ship with the default, jdk-shipped version. For this task, we
will simply wire the default jdk-shipped factory into the appropriate methods: Connection.createQueryObject()
and DataSource.createQueryObject().
