[Abhishek Reddy]

I can able to display all data except image. Image is in the form of byte array. how to display this byte array as image along with other details.

OK, so given that:

A JSP is merely a template to create an HTML page.

HTML has no way of using a byte array to create an image.

HTML does have a simple way of including an image.

You should be able to see the problem with your approach.

So what's the correct approach?

thanks for the reply,

iam using jsp for displaying data.

used jstl core tags for iterating through the list and displaying the same in the jsp

The simple way of adding an image that Bear alluded to is the <img> tag. The JSP would add that tag along with whatever other text information you want to display.

What's left to think about is what URL you would use in the image tag so that the appropriate image can be loaded. It could be something like "http://myserver.com/myApp/imageServlet?id=12345678", and "imageServlet" would be mapped to a servlet that retrieves the image data and streams back the image to the browser. (The CodeBarn actually has an example servlet that streams an image to the client.)
