Connecting with PostgreSQL 8.2 using Java

Question

When I'm connecting to my database (PostgreSQL 8.2) through JDBC it gives an error ClassNotFound and something related to drivers. How do I fix this?

You need to be more precise. Cut and paste the exact error message here. Chances are you just need to include the drivers in the classpath. — Jon Skeet

"and something related to drivers" is not a valid Java exception nor a valid Postgres error message. — user330315

I guess you need to put the postgres jdbc driver on your classpath. You can download it from http://jdbc.postgresql.org/

Latest version 8 or 9 drivers should to (stable) like the 9.0-801 driver. To quote the size :

If you are using the 1.6 JVM, then you should use the JDBC4 version.

@neha: what's so unclear about the sentence: "This is the current version of the driver. Unless you have unusual requirements (running old applications or JVMs), this is the driver you should be using" on the download page?
