Re: Deploying my application (nesting the jar)

So if I extract the jar and include the class files in
my project classpath, do I still instantiate the
driver using:

Class.forName("org.postgresql.Driver").newInstance();

I appologize for my ignorance on this one.

Below is the .classpath file created by Eclipse. The
extracted jar is excluded from the source, but
included as a library. However, I get the "no suitable
driver" SQLException. Also, when I included the Jar as
a library it worked fine, just when I come to
deploying this it gets complicated.

Thanks,
