Applet Help

I haven't done a lot with Java so forgive me in adance. I need to write an applet that can communicate with a USB device. Is this possible? From what I have read applets have limited access to host resources.Thanks,Nathan

Unless they're signed. Theoretically it's possible, though, but USB access means that the user will have to have some libs installed. Which could be done by the applet, if it has full system access.

Thanks for the reply. Sounds like I need to do some reading about signed applets. I have a signature device from Topaz Systems. I need an applet that can be loaded in a browser that can accept a signature. The applet would then submit an image of the signature to a servlet.Nathan

As I said, it won't be easy. The applet has to detect whether some JavaComm stuff is present on the client PC, and if it isn't, it'll have to download it, configure it (if necessary), place the native libs somewhere, and then access the JAR using UrlClassLoader in order to use its classes, because it won't be in the classpath.

It'll be a PITA in the least.
