Re: [Joelib-help] problems compiling joelib: wrong weka library?

I think these things can already be freely discussed in the developer 
mailing list. I hope this will not to much 'developer stuff' for the 
subscribers of the helping mailing list. On the other side JOELib has 
(in my opinion) a 70% developer focus, so the division into help-, and 
developer-mailing list is not really clear. Please write a comment if 
you want to tell us your thoughts ...

I don't care, because that's only one single entry. Because this 
functionality has it's focus on developers, i think they will be easily 
able to change 'protected' to 'public' and recompile the sources. If not 
i can offer a source code patch and/or the ant target for doing such things.
Furthermore i do not find the weka design decision for this class not 
really good. Protected is to restricted for such an important class, 
that like making atoms protected.

Another possibility is to add a simple Mol2Instance class in the weka 
source package to fullfill the protected case.

Adding the weka.jar is definitely possible, but will increment the 
joelib distribution.

And last but not least you can write a wrapper if you like and pick the 
required functionalites from the InstancesHelper from JOELib.

So i think adding somewere a note in the tutorial would be fine, because 
i've an internal CVS version also. That's my way, when developing 
'machine learning' tools and hacking them.
