Re: Connection Problem with JDBC - Mailing list pgsql-jdbc

I just verified that it works under linux as advertised, but still
doesn't work under windoze. Steven, I presume you are trying to use this
on a windows machine?

Steven,

This works for me.

[blind@barry work]$ echo $CLASSPATH
.:/home/blind/work/wfs/jars/postgresjdbc.jar
[blind@barry work]$ java -Djdbc.drivers=org.postgresql.Driver
ConnectDemo jdbc:postgresql://localhost:5432/files blind "" Connection
successful. Connection as String: org.postgresql.jdbc2.Connection@4ac268

I am running on RedHat 7.2, jdk 1.3.1_01 with the postgres 7.2 jdbc
drivers.

Are you sure that the jdbc jar file is in your CLASSPATH, and that you
have exported the CLASSPATH setting back to the environment?

thanks,
--Barry

TIP 2: you can get off all lists at once with the unregister command
    (send "unregister YourEmailAddressHere" to majordomo@postgresql.org)
