Molconverter class not found

I'm working with a python script that was written for Windows, but on a Mac. It calls the molconverter, but when it does I receive the error message:

Exception in thread "main" java.lang.NoClassDefFoundError: chemaxon/formats/MolConverter


Caused by: java.lang.ClassNotFoundException: chemaxon.formats.MolConverter


	at java.net.URLClassLoader$1.run(URLClassLoader.java:202)

	at java.lang.ClassLoader.loadClass(ClassLoader.java:247)

I copied the molconverter binary to the standard directory,  /usr/bin/. Maybe I'm supposed to move another file.

Thoughts as to what I might do to fix the problem? Thanks

Indeed, if you move the scripts in bin they will not find the jar files. I recommend to move back the script to its original location, and either add the bin directory to your path, or add a symbolic link to the script(s), for instance:

ln -s /opt/marvinbeans-5.11/bin/molconvert /usr/bin/molconvert

Yes, that did the trick. I was adding it to the PATH, but only for a single terminal instance. So every time I closed Terminal and tried to rerun the script I had the problem again.

All fixed. Thanks
