Hi,

none of the MarvinView examples on the websites (e.g., http://www.chemaxon.com/marvin/examples/applets/view/colorsets.html) seem to be working for me. All I see is "Applet is loading... Please wait." in the box where the applet is running. This is on Firefox 3.6.17, Ubuntu Linux 10.0.4.

With Chrome (Chromium 11.0.696.57), I only get an empty box instead.

In Firefox, I see an "exception: java.lang.NullPointerException" at the bottom of the browser.

Are these examples still operational?

Thanks,

Christian

I assume that OpenJDK is the default Java on your machine. Marvin applet does not support OpenJDK. It requires Oracle Java.


I had the same problem on my Ubuntu 10.04 machine. Replacing default Java Plugin to Oracle Java Plugin solved the issue on my machine.


You can find several hints on Internet how to install Oracle Java and update default Java settings. e.g.:

If both OpenJDK and Oracle Java is installed, you can select the default java with the update-alternatives tool:


sudo update-alternatives --config java


You can read more about it in the linked ubuntu forum topic above.
