Connecting PostgreSQL 8.1 & ColdFusion MX 7

by Rolando on May.24, 2007, under ColdFusion

So far ColdFusion does not have a default driver to connect to a PostgreSQL Database. However you can manually create a connection using a JDBC driver.

  1. Download the JDBC driver http://jdbc.postgresql.org/ You need to know what is your JDK version so that you can select the proper driver. To check your JDK version open Terminal and type:
    java --version
    In my case I have "1.4.2", therefore I downloaded JDBC 3 for PostgreSQL 8.1
  2. Copy the driver (jar file) to your coldfusion location at:
    [cfRootFolder]/servers/cfusion/cfusion-ear/cfusion-war/WEB-INF/cfusion/lib
    in my case this was:
    /opt/jrun4/servers/cfusion/cfusion-ear/cfusion-war/WEB-INF/cfusion/lib
  3. Restart ColdFusion:
    cd into /opt/jrun4/bin/ and type:
    ./jrun -restart

NOTE: for some reason when

I execute this command it my system won't complete the restart process so I had to do a Stop and Start like ./jrun -stop and then ./jrun -start

  1. Now go to your ColdFusion admin add a new Data Source of type "Other"
  2. Enter your JDBC URL as: jdbc:postgresql://localhost/[your database name]
  3. Set Driver Class and Driver Name as: org.postgresql.Driver
  4. Enter the user name and password.

    Note: You can use your "postgres" user account. I have instead created a specific account for coldfusion, you can create users through pgAdmin.

  5. Submit. You should get an "ok" in the status.

VirtuaWin - Virtual Desktops / Workspaces for Windows

by Rolando on May.24, 2007, under Misc

VirtuaWin is a Linux like Virtual Desktop manager for Windows.  This is one feature that I got used to and use all the time on Linux but was lacking of on Windows.  I have tried other solutions but they were always buggy so I gave up until I tried this one.  I have only been using it for a couple of days but so far is working great.  I was able to customized some shortcuts (i.e. switching from desktops, moving windows from one desktop to another, etc.)

The best part of all is that VirtuaWin is Free (GPL), so give it a try http://virtuawin.sourceforge.net/
