possible configuration error?

Let me start by saying I am NOT reporting a MarvinSketch error here. Rather, we are having a problem with a new test environment and I'm looking for some clues as to what may be wrong on our end. The Marvinsketch applet works fine in our production and other pre-existing environments.

Anyway, in this new environment, drawing 4 carbons, linking them together, and calling getMol on the applet yields and emtpy string and the following errors in the Java console:

Any idea where we could look? I'm guessing there's some sort of configuration error on our new server, but we're a little stumped as to where to look. Any ideas are greatly appreciated.

 

thanks,

I assume that chemaxon.struc.PeriodicSystem could not load chemaxon/isotopes.data or chemaxon/elements.zip.

Please check whether these resources are available in the codebase of Marvin Applet. Marvin searches these files relatively to the main applet jar.

thanks, that led us to the solution. mime types were wrong in the server config. fixed now, thanks again. :)

It is a good news. Thanks for the feadback.
