Re: connecting Hbase using java
which external jab I imported you can see in project tree at
http://i.troll.ws/209459a4.png

your method is looking more nice and sophisticated so I also tried to use
mvn.
but I am behind proxy so I set proxy in ~/.m2/settings.xml
but mvn is not able to connect all the repositories. I dont know why its
able to connect to some but not all
please see this output of mvn eclipse:eclipse at
http://pastebin.ubuntu.com/5664786/

now I am stuck in between mvn. I am trying to resolve it .

if you have any other way please tell me :)
thanks a lot Ted
