[Biojava-l] NoClassDefFoundError

[Hamed, Ahmed A.]

Hi Charles,
This is a common java error when you don't have all the required jar in your
class-path. Problem with Netbeans or Eclipse is that they set the class-path
internally but once you need to use it from another machine you have to
create manage your own class-path.

In Eclipse, not sure about NetBeans, you can export your project as a JAR
and you can specify a MANIFEST.MF file. Make sure this this file exists and
the project libraries that are required on your labtop are migrated to the
new machine and the path within the MANIFEST.MF file is pointing correctly
to them.

Here is what my MANIFEST.MF file looks like when I migrated biojava project
to another machine:

Manifest-Version: 1.0
Class-Path: /home/ahamed/I529Fall2009/HW1/bytecode.jar
/home/ahamed/I529Fall2009/HW1/biojava.jar
Main-Class: mlbio.genes.dna.CodonTableCalculator

Hope that fixes your problem.
Best wishes,
Ahmed
