Re: Unable to access dir on network from GWt app
It may help to try to deploy in a fresh install of Tomcat (downloaded from apache, the bin distribution) executed with root. Most Tomcat distributions (specially the one from Debian) are configured for production mode. It may be really secure, but it's a nightmare for programmers. Once you have it running you can try to look for the differences in the setup and experiment a bit.

File isn't accessing the file but is the representation of a file in a file system allowing you to query informations about it, like the ability to read etc. > However when I debug and run fileObject.canRead() and > fileObject.canWrite it returns false.

No. Most likely Tomcat is running as a unprivileged user (like nobody) or installed a SecurityManager preventing you from accessing parts of the file-system outside the sandbox.
