Its not possible to run a FreeBSD shared library in a Linux executable and vice versa, so yes you need the Linux plugin. > Question 3: The plugin doesn't actually work to run applets. java_vm starts OK, > but it seems that the codebase attribute in the <applet> is not being > interpreted correctly.

Given that the native plugin can't conceivably work with any version of Netscape less than 6, what are you running it in when you attempt this? Also note that due to the above situation there has been zero testing of the Netscape 4 version of the plugin, which is what you would need to use if you somehow had a Netscape 4 version which could use it. > Thanks for any help/insights/clues you can provide.
