I had an applet embeded in share using a client side javascript. The applet invokes custom script in alfresco. The problem is the following exception in share (the result from the script is ok). I use some custom libs in the applet and commons-httpclient 3.1 to communicate with alfresco.

Looks like the problem comes from the commons-logging API which most apache commons library depend on. Is the commons-logging.jar in the applet's classpath?

Looks like you need to play around with the <applet>/<embed>/<object> tags and make sure you make all the .jar files that the applet requires are available.
Try packaging all your custom files in a custom jar file, i.e. acme-applet-extension.jar and make sure to place it in:

tomcat/shared/lib/

Now make sure acme-applet-extension.jar contains all your code and especially the .jars and .properites files (i.e. commons-logging.properties) that the applet depends on inside the jar files META_INF folder: applet-extension.jar!/META-INF/acme/java/

Then make sure to have the <applet>'s "codebase" parameter pointing to something like /share/res/acme/java and see if you can get the applet to work.
You should now get the applet to request /share/res/acme/java/commons-logging.properties instead of giving you an error.

If you haven't invested a lot of time in this already I would recommend implementing this using javascript if possible (YUI or jquery) since I'm pretty sure you will run into additional problems 😞

Cheers and good luck, Erik
