Soap Adpater : Not getting the value of Adapter Engine

Hi

I am configuring a scenario in which I am using SOAP Adapter but I am not getting the value for <i>Adapter Engine</i> parameter as <i>Integration Server</i> while configuring the Soap Adapter.

I used the same configuration in another server & getting the value there but not in this server.

What is an issue & how can i solve this.

Best Regards

Lalit
