Do you know where I can get this patch ? The site ftp://ftp.postgresql.org has been unreachable since yesterday evening, at least from where I reside (France). I tried to browse mirror sites but I did not find there anything such as a jdbc patch related to Jbuilder. > After that, I'm still at a loss as to why the update queries I send are > never > actually updated in the DB.

Anyway, thanks for your reply.

You did use it '-i' switch in starting postmaster, right? (sorry if you have already gone through that one). Also, I don't use the user and password fields but instead supply it in the URL, like so: jdbc:postgresql://some.domain.somewhere.com/database?user=postgres&password=something&auth=password skip Username and Password and put 'postgresql.Driver' in Driver Class. It does work and Aaron has made some head way with the updates. We now just can't update 'DATE' types.

Can't speak for what is happenning on the backend but I know that w/out the auth param I was constantly greeted w/ a dialog box to input my password and userid whether it was in the URL or not. And then it would never accept it.

I found the answer to my question in the FAQ at http://www.borland.com/devsupport/jbuilder/qanda/484.html. (the IDE classpath must be set twice : a first time using the 'tools/IDE Options...' menu and then a second time by manually editing the file jbuider.ini...) So, the so called 'Connection Editor' now passes the connexion test. I have added a QueryDataSet component to my app. and I am at present #trying# to use the 'Query Editor'... Thanks for your help.
