I'm not sure on that sorry. What is the full exception? A NPE sounds a
bit odd, I would have thought you'd get something a bit more informative.

If we were to assume that my data.h2.db is in my data.jar file which

So because a jar file is a zip, does that mean that:
ssConnection = new SSConnection("jdbc:h2:zip:~/
suppliers_and_parts.jar!/suppliers_and_parts", "sa", "");
should get me connected? Every time I've tried that it gives me a null
pointer exception because it is more than
likely looking for a .zip file. I've tried changing it to
"jdbc:h2:jar" and "jdbc:h2:file" but it gives me an exception
saying that it could not load properties.
Thanks for your help by the way.

I remember this coming up before a while ago (but I can't seem to find it).
I think you have to get the path of the jar file and then open it in h2
as you would a zip file, giving it the full path (or relative to the
current working directory).
So you have to use some classloader magic to get the jar file.

Then feed that into the h2 connection string
But there might be a better way :).

Yes, I am trying to make a connection to a DB inside the same jar the
java classes which make the connection will be in.

Do you mean access it via classpath rather than naming the zip/jar file?

Hey, is there a way to make a connection to a db file that is inside a
jar? I know that H2 has a feature that allows connection to a db
inside of zip file but how would I get a connection to a db file
inside a jar?
