Subject Re: How get DB2Connection object from SqlMapClient?
Date Thu, 24 Jan 2008 20:19:51 GMT
Unfortunately, the InvocationHandler for SimplePooledConnection is a private
nested class.

Yes, we can set properties at the DataSource level, but we want to change it
at run time based on the data access "service" being invoked (e.g., for
finer-grain performance reporting).
