Excellent. Please feel free to add a page in the wiki [1], on how to set it up 
in NetBeans, so that other users may take advantage of it... or to just share 
experiences (I use Eclipse...).

Please give the file content, so that I can see what goes wrong.

XYZ files do not contain bond information, and CDK does not do anything you 
did not ask for. Please have a look at the cdk.graph.rebond.RebondTool, which 
allows creating bonds from 3D coordinates.

Only a subset of SMARTS is implemented in the CDK, pending an MQL 
implementation. Adding features is not too difficult, but requires some 
explanation. If interested, please let me know.
