I am not able to build project using ALM12

I go to Manage Jenkins>Configure system>Enter ALM details.
Here when i enter the ALM url which i use for accessing via URL. I get following error - "Error openning a connection to the ALM server"
(I am able to open in IE ALM12 with the same URL as entered in Jenkins.But still i get this error)

Ignoring this error i configure my build with step "Execute functional tests from HP ALM" and enter all details
In test sets i have given the complete path of the test set i want to run
( eg: Root\Scheduler\SchedulerDummy1)

Finally when i build this i get following message:

Console Output:

Run mode is set to: RUN_LOCAL
---------------------------------------------------------------
And i get a round loading symbol which goes on and on....(i waited for 30 min ...but nothing happened.Nor am i getting any error message.

I have to manually abort this build only then it stops.
