What path is iceweasel using to find Java plugin?

[Kent West <westk@acu.edu>]

I've got an app (Banner) that needs a specific version of the Java 
plugin (a 1.4 variant). I've got it installed on my Sid box, but can't 
get Iceweasel to recognize it instead of the 1.5 version.

No matter what I do to disable 1.5, "about:plugins" reports:

Java(TM) Plug-in 1.5.0_04-b05

   File name: libjavaplugin_oji.so
   Java(TM) Plug-in 1.5.0_04



I've run updatedb (as sudo) and then located libjavaplugin_oji.so, and 
then moved or renamed all the 1.5 versions I can find, and yet still 
Iceweasel finds this version. (Yes, I am restarted Iceweasel each time. 
It's getting painful.)

Google has not been my friend, either.

(It would be SO much simpler if the Firefox devs would simply put the 
full path to the filename in "about:plugins"; this sort of thing has bit 
me before, and a full path would have helped then, too.)

Searching for "path" or for "java" in "about:config" didn't provide any 
clues that worked out either.

Where is Iceweasel finding the Java 1.5 plugin that I can't find it?

Thanks!
