hello ,
I am using an applet with two panels one containing the Gui components .The other panel is kept blank and supposed to display images depending upon the values entered by the user in GUI components in the panel .
The display of images should be from server . I need to have applet servlet communication for it . well can somebody suggest me how to send images (GIF/JPEG) display images to an Applet from servlet after mataching in database .
I have done servlet applet communication using text data .well i am using javawebserver 2.0 .
Any help in this regard will be appreciated

Most books on servlets, including mine, have chapters on sending images, sounds, etcetc. The main points you have to watch:
1. Use an OutputStream rather than a Writer
2. Set the content-type in the response with setContentType
3. Set the content-length with setContentLength
4. write the bytes to the stream and close the stream
(Strong-hint) Drop the use of Java WebServer and switch to Tomcat. You will have to some time since JWS is no longer supported, might as well do it now.(/Strong-hint)
