Java Derby with Squirrel SQL

I am using jre 1.6, java db 10.1.3.1, squirrel sql 2.4.1
I follow this instruction
http://db.apache.org/derby/integrate/SQuirreL_Derby.html#Configuring+SQuirreL+for+the+Derby+Embedded+JDBC+Driver
to set my driver (my driver is at C:\Sun\SDK\javadb\lib\derby.jar)

But I keep getting
org.apache.derby.iapi.services.context.ShutdownException:

followed is the stack trace:

I *think* its to do with your default Java version and classpath.

I manage get it to work now, but does not really know what crucial step that I make to make it work. I am using NetBeans IDE 5.5. Last step I make is, open the runtime tab, right click on the Java DB(network), and click "connect using", enter my user name and pasword, click on OK. After that I try to connect using Squirrel SQL, and it works.

Since I have not changed my classpath and install a new java version(I am using jdk 1.6), hence I suspect this is not the problem.

Since I have managed to get it work, I would like to closed this question by refunding.  Thanks for the assistance.
