Jabber Video for Telepresence 4.6 - unable to recognize camera on Maverick OS X 10.9

Got an issue on Jabber Video 4.6 on Mac, it can login but can't recognize the iSight camera after I upgraded my MBP to Maverick.  You need to upgrade to 4.7 in order to fix this issue.  I have upgraded to 4.7.4 and works well on my Mac.

Maverick - No Java runtime present, requesting install

After upgrading to Maverick (OS X 10.9), when I try to run java –version in terminal, it showed the error "No Java runtime present, requesting install", however nothing happens except showing this error message.  The solution is to download the official java package from apple website:
