How to disable news and blogs from Jboss AS 7 and make it fast.

[Vinod Vijay]

Hi, I'm using Jboss AS 7 configured with my eclipse indigo. Everytime I start my eclipse, first time it tries to access some URL like planet.jboss.org, etc and loads some unwanted material like News and Blogs. I want to disable these so that it does not waste time on these. Please refer the attached screenshot which would make you more clear.
Secondly, eclipse also validates the whole project. Checks every file one by one which takes around 20minutes. Is that validation required everytime I open my eclipse? If no, then how can I disable that also.

Thanks
