Apache Jetspeed 2.2.0 with Postgres installation

I attempted my first installation of the binary download of JetSpeed 2.2.0. Using the installer I chose postgres as my choice of database. However, during installation I encountered the following error:

Error running the install,The following error occurred while executing this line:
C:\Apache\Jetspeed-2.2\database\bulid.xml:126;Source file does not exist!

In order to get it working I had to edit the following file:

C:\Apache\Jetspeed-2.2.0\database\database.properties

And change the property value from
db.type=postgres
to
db.type=postgresql

Then in the directory C:\Apache\Jetspeed-2.2.0\database\
type ant

Now you can startup the server and verify it works.
