I am having problems with preload MolExport in MarvinSketch, getting this error:

Perhaps this was my error. I don't see the problem after I clear the browser cache and the Java classloader cache a few times.

Exactly. Mixing new classes/jars with cached ones can cause such kind of problems. Because of it, clearing cache is useful when you try the updated applet.

In order to take advantage of the new features of Marvin 4.1 (in fact, in order to be able to use Marvin 4.1 at all), we need a jchem.jar file that contains the marvin.jar from 4.1. Can you provide?

Szilard can build JChem package but he is on holiday. We will build a new jchem.zip as soon as possible.

Can you show me the example where you have got this nullpointerexception?

Your example works for me.
Probably, different Marvin versions are mixing in your cache. By checking your example on epoch site, your Marvin says that its version is 4.0.5. Since you said that your Marvin was downgraded to 4.0.6 from 4.1.0alpha20, probably the code of 4.0.5 and 4.0.6 are mixing somewhere on your site or in your cache.
By the way, the certification key of signed jars in 4.0.5 have been expired. It worth to update 4.0.6 which was built with the updated certifications.

Really? It doesn't work for me at all. I am using Safari 2.0.4 on MacOS 10.4.7, and I'm pretty sure Rafi is using Firefox on Linux. I emptied my cache and cleared my classloader cache. What browser are you using?
I'll pass your suggestion on to Rafi.

I also use the same platform: Safari 2.0.4, OS X 10.4.7.
It also works on my Linux (Fedora 3, FireFox 1.5.0.5, Java 1.4.2_04).

Thanks, that info told me that the problem was probably related to caching. So I cleaned out all my Java caches, and now I can load the page just fine.

I was able to solve the problem, finally, by clearing out my

directory and restarting the browser. It may be that MarvinSketch 4.1 upgraded some swing or awt libraries that are inconsistent with MarvinSketch 4.0, and those upgrades prevented old things from working.
