[redken55]

It wont let me connect because of an unknown host then it tells me to report here. so what do i do?

[Okabe]

The following commands fixed it on my Debian (linux) box:

# apt-get install openjdk-7-jre
# update-alternatives --config java

then select openjdk-7-jre as default.

if you have a different OS please tell us which one.
