Hello

I have a java based web application deployed on Apache Tomcat.

On one of my JSP pages, I try to display an image, the path of which is
an absolute path (say, C:\somePic.jpg) pointing to a location on the
server on which the application is deployed. However when I try to
access this web page from a different machine, it looks for this image
file on the local machine and not the server. How can I specify an
absolute path but still make sure that the jsp page is picking up the
image from the server and not the local machine on which it is being
run?

Thanks
Swetha

Uh-huh.. well, to fix that, simply... wait (checks sub.)

Sub: URGENT! ....

Oh.. (checks watch) apparently I'm too late.
Never mind.

























[ Look into ServletContext.getRealPath() ]

Thanks Andrew

How can I get a handle to the servletcontext object?

I figured I can use application.getRealPath coz application is of type
ServletContext.

Thanks

Ok, what happens now when I use application.getRealPath(absPath) where
absPath is a string that contains the absolute path of the file (say,
C:\somePic.jsp) is that the absolute path just gets appended to the
path of the application on the server so it ends up as "C:\Program
Files\Tomcat\webapps\myApp\C:\somePic.jpg which still does not work.
Any ideas on what I can do to fix this?

Please don't top post, thanks.

Generally its a bad idea to serve files outside of some predefined
docroot. If you server C:\somePic.jpg, what is to prevent someone from
retrieving anything else on your hard drive? Its best to move the jpg
files into some resource directory under your webapp root.

Good luck,
Daniel.
