[Biojava-l] NoClassDefFoundError

[Richard Holland]

It means that the version of the Java compiler (or the compatibility
flag used on the compiler) that was used to compile the BioJava JARs you
are using is newer than the version of Java available on the machine you
are trying to run the program on! You need to either upgrade Java on the
target machine, or compile BioJava from source on the target machine.
