[Cdk-user] [cdk] Class Cast Exception

[Dr. M. L. <mar...@gm...>]

Hi all,
I am a beginner in using cdk - and even java itself. My problem is as
follows:
I tried to use jmol as a graphical renderer for a cdk - application. I
followed the instructions mentioned in the cdk-news 2.1. 
First I installed the jbuilder, then I put the cdk2005...jar and the
jmol.jar in the projekt classpath. I took the code from the example.
Everything seems to work correct. But at the command:
    viewer.openClientFile("", "", methane);
I get a ClassCastException. 

What is my mistake?
thanx in advance
