Re: [Joelib-help] Problem with java3D

[Joerg K. W. <we...@in...>]

Hi,

eventually you could use:
line 72:
if(config!=null)
{
   moleculeCanvas = new Canvas3D(config);
   mScene = new MolecularScene(moleculeCanvas);
   add(moleculeCanvas, BorderLayout.CENTER);
}

and for all other methods you should add
if(mScene!=null)
{
   ...
}
else
{
   logger.error(...)
}

or
if(moleculeCanvas!=null)
{
   ...
}
else
{
   logger.error(...)
}

If this works i recommend to add these changes to CVS directly to avoid 
this problem for other users ! Unfortunately the Java3D API for other 
platform is often not really up-to-date ...

Regards, Joerg
