T5: xml file location
Hi,
I have this info.xml file that I need to open, first I put it under WEB-INF
and use : fr = new FileReader("info.xml"); got FileNotFoundException, I put
it under images directory as the template was able to get the pictures
there, then I use FileReader("images/info.xml"), same exception. where is
the better place to put xml files and what's the correct path to access
them? thanks.
A.C.

I don't have the time to figure this out right now. I would guess that it's
either a bug in the way tomcat is figuring out the context or in how you are
deploying. You could try passing "ROOT" instead of "app" but I don't know
that it will work. You should search tomcat forums for how this works.

Hi Josh,
I tried your second approach:
requestGlobals.getHTTPServletRequest().getSession().getServletContext().getRealPath("app")
it returns : /usr/local/apache-tomcat-5.5.23/webapps/my_app_context/app
but I checked the running program, the file is here
/usr/local/apache-tomcat-5.5.23/webapps/ROOT/WEB-INF/info.xml
if I set the application context to "/", i got
/usr/local/apache-tomcat-5.5.23/webapps/app and the file still in the same
place, seems difficult to link the real path to the actual WEB-INF, any
idea? Thanks,
A.C.

Angelo,
Look at Tapestry-Upload source code.
There should be an example.

Re: T5: xml file location

Since, I assume, you are deploying your web application into a servlet
container you are not going to be able to use a relative path to get at the
file. Tapestry isn't doing the loading of the file so using any Tapestry
related path constructs is not going to work.
Your best bet is putting your file in the classpath and using the
classloader's getResource or getResourceAsStream methods to load it.
You could also try to use the ServletContext to find where it's physically
loaded on the disk
String path = request.getSession().getServletContext().getRealPath("app");
// app is the name of your servlet/filter
But there are some significant caveats:
If you are using a secure app server then you may or may not be allowed to
read the file from this location.
If you have deployed into a WAR file then this also may not help (if the WAR
isn't exploded).
So, put it in the classpath and use the classloader to find it.

Hi Marcus,
This does not work neither, kind of strange.
