SAP XI 3.0 - Communication channel

Hi All,

Fortuntely I created File to File scenario in SAP XI 3.0

but still I have one querry regarding to configuring communication channel.

In the <b>Module</b> tab I specify this information :-

Number = 1.

Module Name = localejbs/CallSapAdapter.

Type = Local Entrise Bean.

Module Key = 2.

What these parameters are?? They are Adapter dependent or something else? Also could any one tell me the better doccument about it.

Thanks & Regards,

Farooq Farooqui.
