hi all,
i am a newbie using jdbc interface to postgresql.
Information about the machine and pgsql server-
1. system: OS:Enterprise Lnux 4, Server:Apache2
2. PostgreSql 7.4.6

Please tell me that at which prompt(either as a root or postgres user) i
can set CLASSPATH. my jdbc jar file is in
/usr/share/java/pg74.215.jdbc3.jar. i tried as root as well as postgres
user and applied following command:
 export CLASSPATH=/usr/share/java/pg74.215.jdbc3.jar:${CLASSPATH}
After that i looked it with "env" command.it looked well. but when i exit
and reenturned into root as well as postgres user and typed "env" i
couldnt see "CLASSPATH=/usr/share/java/pg74.215.jdbc3.jar".
please suggest how to set classpath and save it.
waiting anxiously
with regard mamoon.

You are a newbie to UNIX :^)

The environment variables you set in your shell are lost when
the shell exits, i.e. when you log out.

In order to make your change persistent, you must write it into a
configuration file that is read by your shell at startup.
Assuming that you use bash, that would be .bash_profile in the home
directory of your user (if you want to set the CLASSPATH only for
this user) or /etc/profile if you want the change for all login users.

Yours,
