| | | Issue with psql driver | Issue with psql driver 2007-09-05 - By Chris Baty
Back
I'm not sure. The code looks like:
try {
con =
DriverManager.getConnection("jdbc:postgresql:test","batymohn","bcl122");
out.println("Conection made");
} catch (Exception ex) {
System.out.println("Error occurred: " + ex);
out.println("<p>NO Connection made</p>");
}
When it throws this exception it comes out in
/var/tomcatt5/Catalina.date.log
