    Subject: applet and DLLs.

Hello,

I have a problem for which I am requesting your help. I would like to
know what I need to do so that an applet can load a dll file. The dll
file is not located on the local machine. I have plenty of clients
wanting to load a remote applet and I dont want to place the required
dll's on all the client machines.

>From my searching of this site, It seems like I need to jar the dlls
along with the class files and place it on the remote host. I did do
this and the remote html file used by appletviewer had an archive
parameter pointing to this archive file.

I signed my jar file using jarsigner. Do I need to do something else at
the client machine so that the signature can be validated?

When I tried to load the applet using the command:

% appletviewer http://intra.versant.com/ravi/index.html it gave me the
error:

load: class test.class not found.
