NullPointerException: Config file not found: /chemaxon/marvi

Hi,


I'm using the Swing version of the Applet in a web browser (IE 6 on Win 2K, Sun JDK 1.4.2). When I try to paste into it, the following shows up in the Java Console:


Config file not found: /chemaxon/marvin/calculations/plugins.properties

(Sorry for the long trace, I wanted to be complete).





Is this file essential? The paste operation doesn't work, even though the applet is signed and it should work.





I see the file in the directory where I unpacked the Marvin Applets distribution. Do I need to copy this file to my applets directory on the web server? Or maybe include it in jmarvin.jar?





Thanks ;)

I copied chemaxon/marvin/calculations/plugins.properties into the applets directory of my web server (retaining the above directory tree). Cleaned browser cache, reloaded applet. This time the file not found NullPointerException goes away. When I do a copy I just get:


ava.lang.NullPointerException

at java.awt.AWTEventMulticaster.mouseReleased(Unknown


...





Ideas?





The Chemaxno certificate shows up correctly when I inspect the certificates in the Java Plug-In control panel. Maybe this is something broken in Marvin 3.4.3 and I should try an earlier release?

Yoav,


You need all files from the package, not just the jar.


If you want a thin installation, I suggest to install the "Marvin binaries" package. See the download page for details:
