File & FileSeekableStream

Question

Hi,
I'm using File & FileSeekableStream to read image files located at W2K(Standard) server, but after executed by a few clients, the following message appears:
Java.io.FileNotFoundException:\\ecms\ImgHome\[email protected](No more connections can be made to this remote computer at this time because there are already as many connections as the computer can accept)
As for the File object, there is no close() method so I can't close it after each execution by client. As for FileSeekableStream, close() means 'Forwards the request to the real File' as documented in api.
Do you think the exception is caused by the 2 objects not closed after used by each client as it is costing too many connections ?
Please advise soon.
Best Regards,
yckok

The Swing application is at client. The Applet is at the server.
Here is the method/code:
File file = new File(filename);
seek = new FileSeekableStream(file);
TIFFDecodeParam param = null;
ImageDecoder dec = ImageCodec.createImageDecoder("tiff", seek, param);
totalPages = dec.getNumPages();
System.out.println("Number of images in this TIFF: " +dec.getNumPages());
// Which of the multiple images in the TIFF file do we want to load
// 0 refers to the first, 1 to the second and so on.
imageToLoad = selectPageCounter;
//selectPageCounter++;
currentPage = imageToLoad + 1;
System.out.println("Loading page: " + currentPage);
pageMessage = "Page " + currentPage + " of " + totalPages;
//op = new NullOpImage(dec.decodeAsRenderedImage(imageToLoad),null,OpImage.OP_IO_BOUND,null);
arrayPlanarImage = new PlanarImage[totalPages];
for (int i=0; i<totalPages ; i++)
     arrayPlanarImage[i] =
     new NullOpImage(dec.decodeAsRenderedImage(i),
                         null,
                         OpImage.OP_IO_BOUND,
                         null);
HEIGHT = arrayPlanarImage[0].getHeight()+15;
WIDTH  = arrayPlanarImage[0].getWidth()+15;
PlanarImage zoomImage = null;
//PlanarImage zoomImage1    = null;
ParameterBlock params = new ParameterBlock();
params.addSource(arrayPlanarImage[0]);
params.add(defaultImagePCT/100.0f);
params.add(defaultImagePCT/100.0f);
params.add(0.0F);
params.add(0.0F);
if(IMG_MODE.equals("1")||IMG_MODE.equals("2")){
     Interpolation interp = Interpolation.getInstance(Interpolation.INTERP_BICUBIC);
     params.add(interp);
     zoomImage = JAI.create("scale",params);
     HEIGHT = zoomImage.getHeight()+15;
     WIDTH  = zoomImage.getWidth()+15;
     //getContentPane().remove(panelImage);
     //panelImage = new ScrollingImagePanel(zoomImage1, WIDTH, HEIGHT);     
else{
     int newTileWidth         = 500;
     int newTileHeight        = 700;
     ColorModel cm            = new ComponentColorModel(ColorSpace.getInstance(ColorSpace.CS_GRAY),new int[]{8}, false, false, 1, 0);
     SampleModel sm           = cm.createCompatibleSampleModel(newTileWidth,newTileHeight);
     ImageLayout il           = new ImageLayout(0,  0,  newTileWidth,  newTileHeight,sm, cm);
     RenderingHints hints     = new RenderingHints(JAI.KEY_IMAGE_LAYOUT, il);
     zoomImage               = (PlanarImage)JAI.create("subsamplebinarytogray", params,  hints);
     HEIGHT = zoomImage.getHeight()+15;
     WIDTH  = zoomImage.getWidth()+15;
     //getContentPane().remove(panelImage);
     //panelImage = new ScrollingImagePanel(zoomImage0, WIDTH, HEIGHT);     
}//end if-else     
System.out.println("Starting add panelbuttons "+op);
// Display the original in a 800x800 scrolling window
//panelImage = new ScrollingImagePanel(op, WIDTH, HEIGHT);
//panelImage = new ScrollingImagePanel(op, 300, 200);     
System.out.println("Height "+HEIGHT);
System.out.println("Width "+WIDTH);
//getContentPane().add(panelImage, BorderLayout.CENTER);
display = new ImageDisplay(zoomImage, Integer.parseInt(IMG_MODE));
System.out.println("display = " + display);
display.setLayout(new FlowLayout(FlowLayout.RIGHT, 2, 2));
//display.rotate();
Panner panner = new Panner(display, zoomImage, 80, Integer.parseInt(IMG_MODE), false, 0);
panner.setBackground(Color.red);
panner.setBorder(new EtchedBorder());
display.add(panner, FlowLayout.LEFT);
getContentPane().add(display, BorderLayout.CENTER);
this.setSize(800,600);
repaint();
getContentPane().validate();Best Regards,
