pure-java, , java HTML4/CSS2, Cobra, Swing . , paint (Graphics g), .

E.g.
Component c = ...; // the browser component
BufferedImage bi = new BufferedImage(c.getWidth(), c.getHeight(), TYPE_INT_RGB)
Graphics2d g = bi.createGraphics();    
c.paint(g);

API- java, JPG.

JPEGImageEncoder encoder = JPEGCodec.createEncoder(new FileOutputStream("screen.jpg"));
enncoder.encode(bi);  // encode the buffered image
