I'm not using JAI exactly (rather the Java2D), but it looks similar. This
is what I have working:
JPEGImageEncoder encoder = JPEGCodec.createJPEGEncoder(OutputStream);
JPEGEncodeParam param = encoder.getDefaultJPEGEncodeParam(BufferedImage);
param.setQuality(0.75f, false);
encoder.setJPEGEncodeParam(param);
encoder.encode(temp);
Hope this helps. If not, you're in over my head...
