Integration Engine!

Hi Gurus,

In the component monitoring:

under Integration server-->

Integration Engine is in Yellow color.

Remaining Business Process Engine, Mapping Runtime and Adapter Engine are in Green in color.

When I double clicked on the Integration Engine, its showing the message "Is Web Service Security available?"

When I am double clicking on the Details button beside the message its displaying the following message:

Details for 'Is Web service security available?'

Communication error Proxy calls are not permitted on sender or receiver side on the IS (client).

Please let me know what could be the error and also send me a solution to solve this issue and mail me at emadduri@gmail.com

Regards,

Lakshmi.
