Video streaming is possible with DV camcorders thanks to the Firewire port (IEEE1394), which works very much like a digital video in/out connection. Basically, the camera just sends video, and if there's a computer attached, it receives the video and decides what to do with it on a computer.
USB doesn't work that way, normally. Most tapeless camcorders automatically set up the webcam as a storage device, which is a very distinct thing from a video streaming device. A storage device is just a disc of some kind... it will show up under some letter (eg, K:) in Windows, when you attach the camcorder.
Some USB camcorders allow for a "webcam" or "streaming" mode... I didn't find any specifics on your JVC, but I know some of the Panasonics support this. There are two ways. One is that, if you have the camera in record/standby mode, it may just go automatically into webcam mode when you attach USB.
The other way is that the camera will have something in the menus, like "Live mode" or "Webcam mode" that instructs it to configure USB for video streaming rather than storage-class attachement.
And of course, some of the tapeless camcorders have a Firewire port, just like a DV camcorder, which is there specifically to allow for streaming video, etc. You could use your camcorder as a web camera over Firewire, given the proper software... though you might find that's just as expensive as buying
And given the price of actual webcams, I would consider buying one
rather than adding wear and tear to my camcorders, just based on
price. This is the same reason I have a DV tape rewind device.. $20 device, $2000
camcorder... easy math.
