Fulcrum ApplicationRoot and getRealPath

[Rex Madden <re...@yahoo.com>]

Hi,
 
I'm migrating my custom services from Turbine based to Fulcrum based.
Does anyone know how I can get a relative path using a fulcrum service?
I used to just use getRealPath off of ServletConfig.  I'm using the
getRealPath method in the init method like this:
 
public void init() throws InitializationException {
getRealPath("myFile.txt")
}
 
but it returns a filename with a null prepended:  
            
            null\myFile.txt
 
Is there a property somewhere where I should be setting the application
root?  
 
Also, is there any documentation on using Fulcrum?  I couldn't find
anything.
 
Thanks,
Rex
