Problems finding the right filepath
Hello!
We are a team developing a webapp running on a tomcat server. We need to
list the files in a certain directory in our application, but we cannot find
a way to always get the correct path on the different platforms and
environments. Is this solvable through some IO-function or do we need to
specify the path to our project in each environment?

Ludwig,
What is your dev language?

Again, getRealPath() is not guaranteed to return anything - it's up to the whim of the container. To quote from the API doc:
"This method returns null if the servlet container cannot translate the virtual path to a real path for any reason (such as when the content is being made available from a .war archive)."

Ludwig, it's been a while, but there used to be a function "getRealPath"
or something very close to that on the ServletContext object where you
can get a system-proper path of a resource. Have you tried that?

We are running Tomcat 6.0.20.

We are developing on both windows and mac. The server is ubuntu.

Can you let the DefaultServlet do it? Directory listings are normally
disabled, but you can enable them for your particular webapp if you wish
Note that there is no requirement for a servlet container (e.g., Tomcat)
to provide *any* access to the underlying file system (if there is one
at all), other than to a scratch area for the webapp's internal use. If
your webapp is deployed as a .war file, there is no file structure to
look at.

You will likely need to specify the path through an environment
variable, Java system property, or within the webapp <Context> element,
via a nested <Parameter> or <Environment> setting.
