images display in jsp from servlet

Question

I have uploaded images to server machine folder like c:images. for this i have written "web.xml" <context-param> <description>Location to display uploaded file</description> <param-name>file-display</param-name> <param-value> C:/images/ </param-value> </context-param>

it is uploading perfectly well. Now i need to display those images in a jsp with <img src=""/> tag.

i am finding the path using

filepath =  getServletContext().getInitParameter("file-display"); 

in servlet and also attached image name. but how to represent in jsp with" <img src=""/> " tag. is there another way to diplay images in jsp from server location folder.

Answer 1

You should be able to access the ServletContext in jsp using the predefined application variable:

application.getInitParameter("file-display");

If you are using Servlet API 3.0 (for EL 2.2, which supports calling methods in expressions) you can do:

${application.getInitParameter("file-display")}
