Hi Michael,
I am working on a project that does something similar.
Please correct me if I did not address your problem.
I have sample codes here. Check it out. It works for my test web page (but is far away
from my real objective)
public class TestServlet extends HttpServlet{
public void doGet(HttpServletRequest req,HttpServletResponse resp){
try{
ServletOutputStream toClient = resp.getOutputStream();
FileInputStream fromFile = new FileInputStream("c:\\help.gif");
byte[] array = new byte[fromFile.available()];
int len = fromFile.read(array);
toClient.write(array);
toClient.close();
fromFile.close();
}catch (Exception e){
ServletContext srvctx = getServletContext();
srvctx.log("Exception by TestServlet", e);
}
}
}
Of course...you might want to add any appropriate method call (e.g setting content
type)
Godspeed,
Lee Seng aka echo5

Hi :-)
from a book "Java Servlet Programming" (Jason Hunter, first Edition,
ISBN: 1-56592-391-X"), from P159, there is a sample of:
- how to "process" an image with GifEncoder(from www.acme.com)
in Servlet-side
- how to send an image to client from Servlet
BTW, I find an WbmpEncoder in the following link:
http://www.alphaworks.ibm.com/aw.nsf/techreqs/wbmpencoder
It is similar with GifEncoder.
