Error in Setting Up the SDK Location and Landscape URL

Hi,

When Setting Up the SDK Location and Landscape URL in eclipse Juno i get the error as

Could not connect to landscape host https://nwtrial.ondemand.com. Mske sure your proxy settings are correct.

I did try adding the host and user (with suffix trial) and password in the network connections area.But still i get the above error.

Could someone please let me know how to maintain the proxy settings in eclipse juno for the SAP NW Cloud ?

Thanks in advance
