I am trying to use Redhat Linux 9, J2sdk 1.4.2 and Postgresql 7.3.2 to
do my setting. But, I cannot access the database to set/get data
through the java program. Please help give me some suggestions.
Here is what my setting and problems:

The postgreSQL .jar file must go in common/lib _not_ share/lib. Two other
things:
1) have you enabled tcpip on the postmaster by seting
tcpip_socket = true
in /var/lib/pgsql/data/postgresql.conf
2) have you edited /var/lib/pgsql/data/pg_hba.conf to un-comment the line
# host all all 127.0.0.1 255.255.255.255 trust
because if you haven't done both of these, you won't be able to connect
from Java.
And before anybody jumps in, I'll just point out that the "host" line is
far too permissive to be used in production but if you're just starting
out experimenting with PostgreSQL and Java, it's one less thing to have to
worry about for now.

Thank you for answering my question
I have moved postgresql.jar to common/lib.
Also, my setting are:
tcpip_socket = true
in /var/lib/pgsql/data/postgresql.conf
host all all 127.0.0.1 255.255.255.255 crypt
in /var/lib/pgsql/data/pg_hba.conf
but, it also cannot work well.
By the way, do I need to set
./configure with-java
if yes, how can I set it?

./configure is used to build PostgreSQL from source. It doesn't affect any
of the run-time settings.
