Subject [jira] Commented: (DERBY-846) Internationalze NetAgent to NetDatabaseMetadata40 in org.apache.derby.client.net

David Van Couvering commented on DERBY-846:
-------------------------------------------

Hi, Kathey.  In those rare cases in the network client where SqlException already has something
besides null for SQLState (which only was happening when DRDA had a required specific SQL
State), I have not changed those SQL States.  They are still consistent with the spec, as
are the error codes.  The only thing that has changed in some cases are the error messages,
as our messages were just too abstruse and cloaked in DRDA-speak.

SQLExceptionFactory40 is responsible for throwing the right subclass of SQLException based
on the type of error.  It does this by looking at the SQLState.  Previously it did not handle
SQLStates as defined by DRDA, many of which indicate a connection exception or a warning,
both of which have specific SQLException subclasses associated with them.   So I modified
SQLExceptionFactory40 to handle the DRDA-specified SQLStates.  This ensures that the right
subclass is thrown and that application code that is looking for a particular subclass gets
it.

David
