Hm, your result class of MoleculeDescriptor.getValueList is wrong, try changing it to double.

Well that's what I thought I was doing. My field in my bean is private List<Double> values; with setter: public void setValues(List<Double> values) { this.values = values; } Does my mapping somehow not match this?

A workaround would probably be to change the double array to a Double list.
