Hi, The simple answer is that you are using sample code from the tutorial that is for a development version, but cdk class files from the release version. What you need is either:
1) use the development branch called jcp-primary (recommended) 2) use an older version of the cdk, where the drawing parts worked unfortunately, the latest release really should not have the Java2DRenderer in (and, indeed Egon removed it for even more recent versions, I think). It has some very nasty bugs like drawing text upside-down (on OSX, at least). gilleain On Fri, May 22, 2009 at 4:53 PM, sebi <sebastian.kl...@hispeed.ch> wrote: > Hi > > I'm having some problems while drawing a molecule with the > Java2DRenderer.
