I recently upgrade from Postgresql 7.3 to 7.4. Of course, I am using the
new jdbc driver.
When I log into my Unix machine under one account, the driver works
great and I connect to the database with no trouble. When I log into the
machine under a different user, I get a ClassNotFoundException.
I've examined my postgresql configuration, permissions, etc., and it
appears to be identical to my 7.3 config, which worked fine.
Any ideas on what is happening? Thanks...
Simple test case follows:
--------- DataBase.java --------
import java.io.*;
import java.sql.*;
public class DataBase
{
public static void main(String args[])
{
try {
Class.forName("org.postgresql.Driver");
} catch (ClassNotFoundException cnfe) {
System.err.println("Couldn't find driver class:");
cnfe.printStackTrace();
}
System.out.println("Testing");
}
}
-------- Example of problem -------
chris:~/test> export CLASSPATH=/usr/local/jdk1.4.2/jre/lib/rt.jar:.:pg74.214.jdbc3.jar; java DataBase
Testing
chris:~/test> su fred
Password:
fred:/home/chris/test> export CLASSPATH=/usr/local/jdk1.4.2/jre/lib/rt.jar:.:pg74.214.jdbc.jar; java DataBase

Check the permissions on the driver jarfile; perhaps it is not readable
as 'fred'.

Wow, thank you. One of the first things I did was check the permissions,
and I believed they were right. I didn't really look at them again until
I read your message. Thank you... now I can go to sleep!
