Ok. You don't give the servlet the full path of an image. You just give an image id in query string. E.g.
http://my.server.com/imageServlet?id=12Id can be whatever: number as well as name.
Then, in your servlet You get this id, then read an image file that is mapped for this id and sends it to browser via servlet output stream.
On the jsp page you write sth similar to:
<img src="http://my.server.com/imageServlet?id=12"/>and your image will be displayed using your servlet. The image file path is needed only in the servlet code to open the stream to file (image file can be stored wherever you want in file system), read it and write to output stream. Read the tutorial accessible via link I provided in the previous post.
