The code is likely is creating an incorrect URL for the image to be accessed. Copy the image URL from the HTML and paste it in the browser - is that where the image lives?

As an aside, you should never do this kind of stuff in a JSP - that's what servlets and backing beans are for. Read up on the MVC pattern to learn why.

Yes,
the url in the browser showing the image properly,
but not showing in the jsp page properly.

What is the URL? If it works in the browser, then it should work in an HTML page.
