Hi,
I am a new user of derby. I would like to learn and contribute for this
project. I successfully compiled the derby source and I tried to run the
SimpleApp.java provided as demo for starting derby in embedded mode.
But, I get the following exception when I run the program. I did not jar
the compiled classes. The classes are in exploded directory structure.
A new directory "derbyDB\log" was created. And derby.log shows the
following exception. I would really appreciate if someone can give
explanation.
Thank you.

java.lang.NullPointerException

Was there any other error from the program or in the derby.log. The
NPE is not the real problem, as u see from the stack it is coming from
the shutdown as part of cleanup. NPE is just a side effect of some
other error.
First thing, I would check is, if there is enough space on the disk ?
What JVM/OS are you using to run the demo ?
Thanks.
