Problems with column names in dot-notation

Hello,
I'm using PostgreSQL 7.2.1 on Solaris 8 (SunOS 5.8). I'm trying to get a
String from my db, using a very simple select command. Executing the
command in psql or even via phpPgAdmin works fine, but when I try to
retrieve the same information via JDBC I get the following error:
"SQL-Error: The column name sometable.somefield not found."
Executing the same command with a field name without the table name
("somefield") works, when the field name is not ambiguous.

If anyone has a solution for this, I would really appreciate it.

My locale and the db-encoding is set to en_US.ISO8859-15 and the JVM is
started with "-Dfile.encoding=ISO8859-15".

Regards, Carsten

Can you get access to the server logs? I do these types of queries all
the time?

The tomcat log gives me only the already mentioned error ("SQL-Error: The
column name sometable.somefield not found.")

Here are two snippets from the postgresql log:

Re: Problems with column names in dot-notation

From

Well it doesn't look like postgres is having any trouble with it. There
would be information in the log saying the column can't be found. Is it
possible that whatever is handling the resultset after that can't find
it?

You are aware that postgres will return postgres will return contact.url
into a column named url?
