You didn't say in which form you have the image in your code, but any Java object can be passed from a servlet to JSP by using HttpServletRequest.setAttribute.

I have done this before. Basically you need to have an img tag in your html/jsp file that uses an action for the src. Instead of "/app/myimage.jsp" you would use "/app/DisplayImage.do?id=123". Your DisplayImage action would pull the image out of the database and stream the contents to the response. Your action would then return null from the execute method. I do not have the source code handy, but I could probably dig it up.

Sample code from one of my sites:

public ActionForward execute(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response) {
 
LOG.debug("Creating image from Blob");
String listingId = request.getParameter("listing");
Blob imgBlob = listerFacade.getListingById(Integer.valueOf(listingId))
.getFile().getFileBin();
try {
byte[] picBytes = imgBlob.getBytes(1, (int) imgBlob.length());
response.setContentType("image/jpeg");
response.getOutputStream().write(picBytes);
} catch (SQLException e) {
LOG.error(e);
} catch (IOException e) {
LOG.error(e);
}
 
return null;
}

Hope it helps!
