Integrating an applet - getting a routing error

Hi,

I've got to integrate a Java applet into my Rails app. The applet
runs a signature capture pad. I've got the basics working in a test
app but I'm getting a routing error I don't understand. This is the
first time I've messed with Java since '96, and the first time ever
with an applet, so I'm sure it's just a 'schtupit newbie' mistake.
Sure would appreciate any pointers.

Whenever I display the page with the applet in it I'm getting (first
line of the trace only):

ActionController::RoutingError (No route matches "/com/topaz/sigplus/
SigPlus.ser" with {:method=>:get}):

I'm confused about a couple of things.

First, the applet appears to be working despite the error that Rails
is throwing.

Second, the 'call' above is made by the one of the vendor's libraries
I've installed under the public directory. It must be, because there
is no method invocation for this in the java code I've written, and
certainly nothing in the Rails code. Why is Rails getting involved?

Thanks,
Bill
