I am using RedHat Linux 9, Java2 1.4.2, Tomcat 4.1.24, PJA 2.5
and I try to load an image from a file, resize it and then output it from my servlet.
There is no X server running.
The image loads ok, but the servlet blocks when I try to resize it.
Does anyone have an idea of why this happens?

The critical part of the servlet looks like this:

Frame dummyFrame = new Frame();
dummyFrame.addNotify();
Image image = dummyFrame.createImage(imageWidth, imageHeight);
Graphics g = image.getGraphics();
while (g.drawImage(map.image, 0, 0, null) == false)
try {
Thread.sleep(50);
} catch (InterruptedException e) {}

image = resize(image, map.imageWidth, map.imageHeight); // BLOCKS HERE

Thanks,
marian

p.s. By the way, it also blocks if I try to make a
dummyFrame.dispose();

What is exactly doing this resize method ?
