[Jode-users] NoClassDefFoundError

[Yang Z. <yan...@gm...>]

Hi, I can't seem to get jode to find my class file (tried pwd and .). 
Thanks in advance for any help.

$ ls edu/cmu/neuron2/NeuRonNode.class
edu/cmu/neuron2/NeuRonNode.class

$ java -cp .:jode-1.1.2-pre1.jar jode.decompiler.Main -c `pwd` 
edu.cmu.neuron2.NeuRonNode

This probably is a problem with class version.  Sun is incrementing
the version of their class files with each major release.  I think
jode-1.1.2-pre1 still checks that the version is in the supported
range (JDK 1.0-1.3).  I have removed this check completely, now. I
should probably make a new release, but the current version is a bit
buggy: It shows lots of unnecessary casts.  Nonetheless, the class
files it produces should be compilable.

For JDK >= 1.5 there are still problems with try-catch and
synchronized blocks; the algorithm should be mostly rewritten to
handle them.  Unfortunately, I do not have so much time I spend on it.

So try the svn version (the trunk uses an ant build script so it
should be easy to compile).  You need a subversion client to download
the repository.

Regards,
  Jochen
