getting the disk absolute path of a web-app

[yair]

hey all
in a servlet running in tomcat, how can i get the full path of my web
application on the disk (something like "c:\progran
files\tomcat\webapps\myApp")?
i don't want to write it in the web.xml or to pass it as a system
property.
thanks
yair

javax.servlet.ServletContext.getRealPath(java.lang.String)

HTH

javax.servlet.ServletContext.getRealPath(java.lang.String)

However, this is not guaranteed to not return null. If, for example, your
web-app is running from an unexploded WAR file, you won't get a useable
value.

Adding to the response by Will Hartung; for what would you need this;
what would you do with the information? Once we know that, we may be
able to propose alternative ways of solving the problem.

thanks for u're answer first.

i will have a folder named "tests" under webapps/myApp, and i want to
read the names of the files in this folder. i m going to show the user
a page with the names of those files and let him choose a file to run
(this ofcourse is a very simplified version of what i m trying to do).
this webapp will not be JAR-ed, so i dont have a problem with that.

it seems like:
javax.servlet.ServletContext.getRealPath("")
or
javax.servlet.ServletContext.getRealPath("/")
r working fine, i think i'll use this way.
thanks
