Answer 1

I got it.......
Just Generate transaction security key and give the generated key as password.
Able to connect successfully.
Steps to create key
Using a web browser, navigate to the CyberSource Enterprise Business Center (EBC) Test Environment login page
Log in using a username with Administrator credentials
Click Account Management from the menu bar on the left side of the screen
Click Transaction Security Keys In the expanded sub-menu,
Click the link, Security Keys for the Simple Order API on the Transaction Security Keys page
Click Generate Key
At this point you may see a pop-up dialog box asking if you want to block dynamic content on the page. Select No if this dialog box appears.
Click Generate Certificate Request when it appears (it may take a few seconds to load)
When the key generation script is done, a dialog box will appear which asks you to select a location on your computer where the new security key will be saved.
Save the key (the naming convention is <your merchant id>.p12)
Deploy the key to your system
