What is the difference between javaw.exe and java.exe ?

The javaw.exe command is identical to java.exe, except that with javaw.exe there is no associated console window. This implies you can't get it to display the version with -version, since there is no console to display it on. Use javaw.exe when you don't want a command prompt window to appear. The javaw.exe launcher will, however, display a dialog box with error information if a launch fails for some reason.

Mounting NFS share directory from D-link DNS 320L on Ubuntu 12.04 LTS

Seems like the steps on how to get the NFS mount point from the D-Link DNS 320L NAS server were not properly documented in their user manual. After setting up and enabled the NFS service on the D-Link DNS 320L NAS server, I went ahead to setup and mount the share directory/folder in Ubuntu 12.04 LTS assuming the mount point in NAS was /Volume_1/... but that is not the correct mount point to start with! Found this answer from D-Link forum post from a member (ba43123) that helped me to correctly mount the NFS share directory/folder on Ubuntu 12.04 LTS: After spending most of the last hour on the phone with D-Link Technical Support, I came away with the recommendation to take my Mac (which has successfully connected to a number of NFS shares in the past) to Apple to determine if the network settings for NFS are correct.  This is mostly due to the fact that the people who are taking the calls have no information about NFS in their scripts and Knowledge Base so they are at a total loss in
