Re: [Springframework-developer] JdbcUtils.extractDatabaseMetaData

[<jue...@we...>]

Thomas,

In a last minute change before the 1.0.1 release, I've renamed =
DatabaseMetaDataCallbackHandler to DatabaseMetaDataCallback, in analogy =
to PreparedStatementCallback/HibernateCallback/JdoCallback etc. In =
particular for names that are long enough already, I suggest to stick to =
*Callback for consistency. I hope you don't mind the change; I didn't =
want to delay the release any longer.

That must have been an old comment that I forgot to change.  I have
modified it to reflect that this method does throw a checked exception
since we can't rely on the exception translation to be initialized when
this method is called.  This method is infrequently used and I'd rather
force the use of a catch block instead of relying on calling code to
check for a null returned.

Good point.  I have moved it.
