Can this code get the path of app ?
S.servletSession.open_!.getServletContext.getResourcePaths("/")
But it doesn't work, and show this message.
-> value servletSession is not a member of object
net.liftweb.http.S
What's the method can get this path string in the lift ?
G:\project\demo\src\main\webapp\images
( To save the file into this path, G:\project\demo\src\main\webapp
\images\003.jpg )
Cheers,
Neil
