Re: PostgreSQL 7.3.1 multiple schema select query error:

On Fri, 7 Feb 2003, waimeng wrote:

The Exception is thrown in
public java.sql.ResultSet execute()
method of QueryExecutor.java

This method implements the native protocol of postgres server/client
communication.
So, the message is actually from the backend.
See line 104:
errorMessage.append(pg_stream.ReceiveString(connection.getEncoding()));

and then
if ( errorMessage != null )
throw new SQLException( errorMessage.toString());

and thats where you get your Exception.

Be sure you have the right postgres-service.xml
in /usr/local/jboss-3.0.3/server/default/deploy/.
(or whatever it is for windows).
(Could it be that you are pointing to a 7.2.x backend??)

Also place your postgres jdbc driver in /usr/local/jboss-3.0.3/lib/

Do a simple test
Quit any app that uses the DB.
start your jboss, and then invoke some pages that use your database.
then do
ps -ax | grep postgres

Do you see any lines???
If yes then are you sure you are running 7.3.1???
If no then you are hitting another server.
