Hi.
I've been trying to solve it myself, but I give up.

Have you given up prior to consulting the documentation?

I need to convert BufferedImage to byte[]. I'm using
com.sun.imageio.plugins.jpeg.JPEGImageWriter and everything works
perfect, expect the writer keeps compressing all images, and the
quality of output is really poor :(
....
writer.write(iioImage);

A quick perusal of that documentation suggests..
<http://java.sun.com/j2se/1.5.0/docs/api/javax/imageio/ImageWriter.html#write(javax.imageio.metadata.IIOMetadata,%20javax.imageio.IIOImage,%20javax.imageio.ImageWriteParam)>
...combined with..
<http://java.sun.com/j2se/1.5.0/docs/api/javax/imageio/ImageWriteParam.html#setCompressionQuality(float)>
...should do what you want.
