hello everybody,
I am in an acute problem, i will be grateful if anyone can help me.

i need to display image in the ".jsp" page. i have created a folder called "image" in the web folder of my project. in the image folder i am storing all the image.

in my database there is one column "ma_image", here i am stroring the filename of the image, say in my "image" folder the image name is "house.bmp" and in the database i am storing "house.bmp" in the "ma_image" column. i am just typing the name of image along with the full extension, i am not using any OLE object to store the image.

now i want to display the image after retrieving it from the "image" folder of my project. the location of "image" folder is:- E:\HomeJsp\web\image

my code is like this::

String path="image/";
//String path="E:/HomeJsp/web/image/";

out.println("<tr><td class=\"menu_tdtd\">Image: </td> <td class=\"menu_td\" id='macImage"+f+"'> </td></tr>");
// out.println("image displayed:-:"+path+"msg");

But i am not getting the image. my output is the filename of the image like-- "home.jsp" it is written in the <td> tag of the browser.

please get me a solution to this problem as soon as possible.

Thanks in advance.

You are using out.println() is a JSP to emit HTML?

Firstly, there should be no Java code in a JSP at all. And the whole purpose of a JSP is to server as template for HTML, so putting the HTML inside a string, inside Java, is complete inside-out.

You really need to update your JSP knowledge.

That said, you cannot use a file path to reference your image. The file path only makes sense on the server machine and has no meaning once the HTML has been served to a client.

You need to either:
  • Put the image file somewhere that it can be served via a URL.
  • Write a servlet that can read the file from disk and stream it as a response.

    Wht to write a servlet code for this ??? i think the jsp itself gets converted to servlet..so why write a seperate servlet code for this..

    What happens to the JSP is completely irrelevant. It's the URL of the <img> tag that matters.

    And if the image is not addressable by URL, then the way to fetch it is to have a servlet (that does have a URL) fetch and stream the image as its response.

    The easiest solution is, of course, to simply move the image to somewhere that it can be served by the server.
     
    It is sorta covered in the JavaRanch Style Guide.
