Re: JDBC connection issue

Sorry to address everyone in the list with the java questions. I am a newbie at Java and PostgreSQL who's trying to resolve why the jdbc driver isn't working. One question to another has led me here...

I will try to address the list with more jdbc specific questions in the future. Thank you for your replies.

best regards,

YJ

I would try

....../postgresql.jar:/home/youngnam/Developments/java_apps/xlang/src

(Has to be a directory or .jar).

Couple of more things:
1. I am not your private java support engineer. It is considered *really* bad
form to directly address listmembers like you did.
2. Reading a java introduction may help you here.
