I want to use the JAI class to develop a applet which can display and manage the tiff image file in the web browser. the applet is using the URL class to instance the tiff file from the webserver. My developing tools is jbuilder 6ee, I find the applet which can run and display the image of coming from webserver when I use JBuilder applet runner to debug it. the applet isn't running and displaying in the web browser. but other applet componentes can be displayed. the error always is be out at the browser status banner that is the 'found the getSource method'. Why don't add the jai class into the applet jar package to running for display tiff image?? please help me.
