See that it added the postgresql driver postgresql-8.3-603.jdbc3.jar Right-click the project node and choose Generate. For PostgreSQLâ„¢, you would use: Class.forName("org.postgresql.Driver"); This will load the driver, and while loading, the driver will automatically register itself with JDBC. After I document this, do I reassign back to you for a fix in a future release, or is this deemed to not be a bug? WEB-INF/lib if you are connecting to PostgreSQL from Java Web Application.

That JAR has to be dropped straight in /WEB-INF/lib folder of the web project without fiddling with the Build Path in the project's properties. It seems that when I create the project and use Glassfish and then switch to Webrick it happens, but if I use Webrick from the beginning it doesn't. Putting the JDBD jar file in $HOME/nbrubyide/ruby1/jruby-1.0.1/lib Here is my current CLASSPATH CLASSPATH=/home/cag/nbrubyide/ide8/modules/ext/postgresql-8.2-506.jdbc3:.
