Exception in thread "main" java.lang.NoClassDefFoundError: org/bouncycastle/jcajce/util/JcaJceHelper

Hi,

I'm relatively new to Java so I'm unsure if this is a mistake on my part or
not. I have been using the example code to build out a utility that signs
files and puts the signature in a ZipEntry comment for validation. At this
point I'm just trying to generate a keypair and I'm getting the following
error:

My function is a copy/paste of the RSAKeyPairGenerator.exportKeyPair
function. The troubled code is in RSAKeyPairGenerator.java on line 53. I
downloaded the sources for bcpg-jdk15on-159.jar and there doesn't seem to
be any jcajce or util folder and no sign of a JcaJceHelper class at all?

Any input would be great.

Thanks for the wonderful library. I look forward to putting it to great use.
