Hi Masch:
This is going to be a very hard one for anyone to help you with ... unless your
shapefile has a ".prj" file. Can you check?
The thing is the shapefile is recorded against a specific model of the world
described by a CoordinateReferenceSystem. GeoTools can help transform your
geometry into lat/lon - but you need to tell it what your data is measured in
first.
Do you mind going through the tutorials on this topic; and then coming back if
you have any more questions? (The tutorials have pictures and everything):
- http://docs.geotools.org/latest/userguide/tutorial/geometry/geometrycrs.html
- slides:

Best of luck
