FW: LISTEN/NOTIFY support in JDBC driver?

Hey David,

I've forwarded the thread from a few days ago regarding async client
notifications using the PostgreSQL JDBC interface.  Barry answered that it
was possible, but I've been unable to get the code to work.  Anyone got
working LISTEN/NOTIFY code uding JDBC?

Thanks for any help,
Ben

Hey all,

I've tried selecting from the db in between checking for warnings, but still
no luck?  Does anyone have JDBC code that issues a LISTEN, then reaps
notifications from the connection warnings?

Much thanks!,
Ben

Ben,

Since the jdbc driver doesn't poll the server, you would only see
notifications after interacting with the database in someother way.
Thus you will periodically need to issue queries to get the
notifications to be read.  (note I havn't tried this, but from looking
at the code this should be the case).

thanks,
--Barry

Ben,

I was looking into this a bit more tonight.  I have gotten some
notifications to come through.  But not all.

If you apply the following two line patch to current sources you will
get notifications if (and only if) you run with autoCommit = true.  If
you set autoCommit to false the backend never sends the notifications to
the client, and I have no idea why.  I plan to follow up on that.  Given
that this only partly works, I don't want to commit this change into 7.2
as it isn't complete and 7.2 is too close to release.

thanks,
--Barry

Barry, do you have a patch you want to apply for 7.3?

This is now fixed in current sources.  See
