The results come back in a single hit which is defined in a JSP page. The JSP consists of a text table representation of the database results at the top of the page and a graphical clickable image of those results underneath. The struts1-based version of the code which I inherited has the action querying the database, drawing an image to a temporary file, which is then referenced from within the JSP. One of the problems that they had with the old version (which is being replaced for a huge number of reasons, not just this) was the management of "temporary" files broken down frequently resulting in file system chaos. I would rather avoid writing stuff to file that can be streamed and forgotten. I know how to get the stream returned and I can happily generate the image as a stream and return it. I don't have a clear picture in my head though about how to generate that image as a stream embedded within a JSP. My prototype has the jsp reference the graphic-drawing action as the source of an image. However, if I implement that, I'll need to extract the data into the action that presents the jsp text and generates the image and its source reference. I'll also need to extract the data into the action that generates the referenced image and still find a way to dump back the html imagemap coordinates and urls to make that image clickable. I'm clearly suffering a brain-fade here. Is the temporary file route the way to go or is there something smarter and more "self managing" that I can do? Later, Andy -------- Yada, yada, yada...
