Showing various images on browser using JSP and Servlet

Question

Hello Guys!
I am starting to develop in Java and already I am facing a big problem.
If somebody will have some tip or suggestion, will be very well comings!
The application must present in browser images originnally of format TIF. As it is not a native format of the I.E. , I converted the image for JPG (without saving it on disk) and send it to the browser a encoded image (encode) using JAI library in one servlet had access by a JSP. Then, the structure of my application is thus:
1) an archive JSP draws the initial screen in browser and presents one input text.
2) later that the user places the parameter, I make an access to the database and read a quantity of images to be presented.
3) From there in the proper JSP, I use de tag img src to send image to the browser in agreement archive the amount of images.
It follows the code of the JSP:
<% 
                int intI=0;
                int intCont=0;
                if(blnImagem == true){
                    out.println("<br>");
                    out.println("<table border=0 STYLE=border-collapse:collapse>");
                    out.println("<tr>");
                    for(intI=0;intI < Processo.intQtdImagens;intI++){
                       Imagem.strImgTif = Imagem.IndicarImagem(Processo.strNmPath,Processo.strSubPath,Processo.intNuImagem,intI);                                                                    
                       out.println("<th>");
                       out.println("<table border=1 STYLE=border-collapse:collapse rules='cols'>");
                       out.println("<tr>");
                       out.println("<th>");
                       %>
                         <img src="ShowImg" WIDTH=100>
                       <%
                       out.println("</th>");
                       out.println("</tr>");
                       out.println("</table>");
%>and code on the ShowImg servlet:
        response.setContentType("image/jpeg");       
        ServletOutputStream sos = response.getOutputStream();
        RenderedOp src = JAI.create("fileload", Imagem.strImgTif);           
        ImageEncoder encoder = ImageCodec.createImageEncoder("JPEG",sos,null);       
        encoder.encode(src); 
        sos.close();The problem is if I have 10 images to present, it WILL BE it is executed 10 times and it passes 10 names of different archives, but in the page only the last image is presented 10 times. It is as if it processed the TAG to the end of everything in way that the value of the static variable Imagem.strImgTif was chore only with the last value and the same loaded image 10 times. How I make to solve this? Somebody has some idea?
THANK YOU !

If I understand correctly what your problem is:
Do this in the jsp:
out.println("<img src=\"ShowImg?image=" + intI + "\" WIDTH=100>");
In the image servlet, get the "image" parameter and parse it as an int. Move the Imagem.IndicarImagem() call to the image servlet.
