Classpath Help - Adding a Jar File to the Classpath of a Project

Hello everyone,

I am attempting to add a jar file to the classpath of a project so that I can utilize classes in the jar file. For some reason I keep getting the following error: ‘Exception in thread “main” java.lang.NoClassDefFoundError:’.

Please help! I do not know what I am doing wrong. I add the classpath by 'Project/Properties/Java Build Path/Libraries and add the location of the jar file. I am trying to add BioJava.

Which build system (Ant, Maven, etc.) are you using? How to properly configure the classpath depends on that.
