You could try one of these update sites / zips.
Or you could move up to Eclipse Luna and use something more recent.
If you're willing to try the bleeding edge, there's also new Fuse tooling for Eclipse Mars, but it's only an Alpha release so far.
Still unable to download from any of the sites.
Does fuse has jars so that i can use it for programming for better understanding or if possible provide me with some example usings jars.
That would be more helpfull.
Not sure what you are asking for. If eclipse tooling for Fuse then try use a recent version of Eclipse and download our tooling via eclipse marketplace. If you cannot do that I assume it is because your firewall for some reason block installs.
With your question about how to use "jar" files then I reckon that is for just basic "how to use fuse" and here I suggest posting on the Fuse forums as opposed to the eclipse tooling forums.
