Display image (from database) in JSP


I would like to know how to display an image in a JSP page within a for loop. The image is accessed from a database. Below is my code and i'd like the image to be exactly where the line "<img src="<%= product.thumbnail %>"/>" is.

Short and simple chunk of my code:

<%
    for(int i=0; i<keys.length;i++){
        Product product = sdb.getProduct(keys[i].toString());
        out.println( "<p>" + product.title + "    " + "<img src="<%= product.thumbnail %>"/>" + "</p>" );
    }
%>

Thanks

  <input type="submit" value="Place Order" />

Solution

  • I think you have a little more work to do to get this going. The img<> tag expects a URL, and cannot magically convert a database blob or similar to a URL.

    My approach would be:

    • Create a servlet that serves thumbnail images from the database, and publishes URLs like /myApp/product/thumbnails?productId=12345
    • Test your servlet from a browser
    • Change your JSP to create these URLs.

    Good luck.
