JSP + Images

Hi,

any info on this would be cool:

i'm trying to create a JSP page and display an image that is stored on the file server and contained within the war file...there are numerous "image" directories within the application

but when i do <img src="<% request.getContextPath(); %>/images/example.jpg"> from within the jsp page the image isn't displayed

the parameter request.getContextPath displays nothing when i check it...so how i can set the contextPath also?

Cheers,

Niall

Niall, If these images are contained within the war file then they are static images. So why do you need to build a dynamic url?
<img src="<path>/images/some.jpg"/> should work just fine.

Becasue hard-coding the context path is an egregious violation of best practices.

Look at your code very carefully:

<img src="<% request.getContextPath(); %>/images/example.jpg">

Do you see the error?

Compare it to the code in the JSP FAQ on this issue.

P.S> If your web app is the root context, the context path will be the empty string.

Hmm, doesnt look like I said hard-coded anywhere. Guess I should have said web app like your above comment to be specific.

I just reread your post and it still sounds to me like you were advocating hard-coding the context path. Glad to hear that you were not.
