Run method every X seconds

Question

Hi all,
I have a method that I would like to run every 200ms from a JSP page. I figured this was more related to Java programming than JSP, so I'm posting here. Let me explain why.
I have an application that captures a still image in the form of a byte[] from a video camera (capturing the video feed is not an option; it can only capture a still image from the camera). I then convert the byte[] to an RGB image and display that image on a webpage using JSP. I would like this image to be updated on the JSP page at a frequency of 5Hz, or 200ms. To do so this, I figured I'd need to call my getRGBImage() method every 200ms and consequently call the ImageIO.write(...) method. This brings me to some questions.
1) Can this even be done? Is 5Hz too fast for all of this to execute?
2) If this can be done, how would I go about doing this? Is there a better way than calling a method every 200ms? Should I use Timer? If so, how would I use it? I read the API, but I don't see how I can apply it.
If I need to post any code or whatever, please let me know.
Thanks,
Dan

Answer 1

Yeah, you would use the Timer in the applet. I assume
the applet would need to connect to the server and
get the latest version of the image at each tick of
the timer.I can have an ongoing connection with the server, I just need to call the method to retrieve the image data multiple times. The server provides me with a method, imageAcquisition, that I call with
byte[] in = imAq.imageAcquisition; //imAq is the server proxyTherefore, I shouldn't need to initialize a connection to the server every time I want to retrieve the image data.
Anyway, that solves my general problem, so any more-specific problems related to applets/timers/etc I'll put in a new thread.
Thanks again,
Dan
