Barcode error on headless Unix environment

Please consider me a newbie on this topic.  Everything works great on my
laptop, but when I attempt to create barcodes in a PDF on our Unix server,
I'm getting this error:

---------------------------

Exception in thread "main" java.lang.NoClassDefFoundError

I'm using j2sdk 1.4.2 on my laptop.  The Unix server is running j2sdk 1.3.
Any assistance will be appreciated.
