please give the naswer guyz i m with it now from last five days and not able to enjoy ruby efficiently.....................

hanks dear but when i tried it from repo browser and tyeped the url of plugin it gives me the tree but doesnt give the plugin it doesnt installl that...means if we repo the url

http://svn.techno-weenie.net/projects/plugins/acts_as_authenticated

then http://svn.techno-weenie.net…project…plugins…act_as_authenticated

opens but there is no file in act_as_authenticated.......if i desire to see wats in d folder it gives me the following error.... error:* propfind request failde on '/projects/plugins/ act_as_authenticated........... could not resolve the hostname'svn.technoweenie.net'

the locsl server does not respond to an authoriative server.......

i have also repo browser the svn but even it is not giving me the perfect answer....and giving me the error as propfine request failed
