General doubt about devices

I have one general doubt abt devices.
Do all devices come with an SDK so that any language can interact with them?.

Whats does it mean if i say that i need to build a CAB file for the devices
and use them in my html object tag.

Can programming languages like java(applets) or asp interact with devices
once if we specify the classid and the cab file location(codebase)

 

No, that is entirely dependent upon the decisions of the manufacturer.

Can we have some context here?

That depends upon 1) the device and 2) the code inside the Java package.

 

What i need is if we r using an ActiveX Component then we pack the .ocx and inf file into a cab file and give the location of the CAb file in the codebase attribute of object tag.

When the browser renders the page, it will look into the classid attribute of object tag to see whether there is an entry in registry if not it will go to the location specified in the codebase and get it registered locally.

As you know ActiveX works only on windows.

I want to implement the same thing in a platform independent way.
So i chose java applets.

Now i don't know what to do in this codebase part.

i need to install the device driver files and all from the server once a person view the web page.

when we use activex the classid field represents the device but when we use applets thats the version of java being installed.

Can any one suggest an idea to move.
