NULL POINTER when opening some MarvinsKetch features

Hi,

I am integrating marvinsketch (Jchem 5.2.6) in a GUI by using the following component : chemaxon.marvin.beans.MViewPane

JPanel viewPanel = new JPanel(new BorderLayout());


MViewPane view = new MViewPane();


viewPanel.add(view);

when using some features of the MViewPane such as the button to display "The periodiс table of the chemical elements" or by cliking on Menu->Help->"About marvinsKetch", I got some NullPointerException (see the stacktrace below):

However, most of the others features work fine!

The only archive I am using is jchem.jar. Am I missing something here ?

Thanks for your support.

Stephane

I have created a small example. Hopefully, it is similar to your application. I have tested 5.2.6 with this example. It works fine for me.

$ javac -classpath ".;lib/jchem.jar" Test.java

$ java -classpath ".;lib/jchem.jar" Test

Are you sure that all jars are preserved in jchem/lib directory (beside jchem.jar)?

Do you use the proper Java version?

Hi Tamas,

thanks for your answer.

forms-1.1.0.jar was missing in my path. The strange thing is I would have expect a "ClassNotFoundException" instead of a NullPointerException with this missing jar.

Anyway, problem is resolved.

Thanks again.

I am glad that the problem has been solved. Thanks for the feedback.
