How to Retrive Information about USB Disk through Java?

Hello,
i am new to java , i want to make a website somwhere in the world that when i put the link in the Browser and press enter
it goes to the URL and then checks the USB in the Client PC and get information about the USB like
serial,Vendor and anything.
i don't want to install any agent on each Client Pc , the websited will need to get the infor somehow.

any ideas or directions?

For this to be possible, the Client PC is going to need to have some kind of client software on it listening for connections and commands. This is also needed to gather information about the drive.

How are you planning to gain access to the Clients PC otherwise?

I don't want to install something on the client computer. because the PC can easy be a ThinClient, so it does not help with an agent.
some other workaround , if you think it is possible in any other language it could also be a soloution for me .

See post on other thread.

Use a signed applet.....and that might do the trick.
