Обсуждение: JDBC Driver Munging My Text?
We are seeing some strange behavior in our system that uses Postgres 7.1.3 and JDBC. System: Red Hat Linux 7.1/Intel. Basically what we are seeing is that text stored in a VARCHAR is entered like this: "hello, how are you" is stored like this: "hello ,how are you". Notice the space and comma being transposed... The plot thickens... This is on a new server. The old server, also running 7.1.3, though built quite a long time ago, does not exhibit this behavior. Any ideas? Known bug? Strange config? It is possible that I built the JDBC driver on the old machine and just copied it to the new machine... I can't remember but it shouldn't matter, should it? Thanks, Hunter

No ideas to fix it, but I can add the info that it has never happened to me using the jdbc7.1-1.1.jar or jdbc7.1-1.2.jar driver files. We have one field, "full name" in our db that is of the format "Smith, Joe", so I think I'd have experienced the problem if it exists in our system. (Debian 2.4, PGSQL 7.1.3, IBM Java 2 compiler & vm) I'd suggest downloading one of the precompiled jar files & dropping them into your misbehaving new server, just to eliminate any possibility that the build is involved (though I can't see how it could be...)

Dave-
Here's where I am at now:
I have replicated it on another machine. This is leading me to think it
might be my app but I am very skeptical because this part of the app is very
simple. Anyway, I am adding a bunch of logging to try to figure out where
things are getting screwed up.
I'll report back here.
Thanks,
Hunter

I have found that it was a bug in my Servlet container, not my code or
PostgreSQL.
