SAP Transaction in EP iView

Hi,

I am trying to create a SAP Transaction iView in EP.

When using SAP GUI for HTML i am getting the error as

<b>Portal Runtime Error

An exception occurred while processing a request for :

iView : N/A

Component Name : N/A

Application URL ':///webgui/!' is not valid! Please check the protocol and host entries for system</b>

When I try with SAP GUI for Windows, I get "<b>Connection to partner broken</b>" error.

I am also not able to get the desired result with SAP GUI for Java.

Can anyone please throw some light on this?
