import com.sap.aii.mappingtool.* show error in PI 7.1 adapter module

Hi

Experts,

i have an adapter module for 7.0 and i am trying to replicate the same for PI 7.1 in 7.1 NWDS.

i have made the required changes as mentioned in stefan's blog :/people/stefan.grube/blog/2008/12/11/adjust-your-pi-70-adapter-modules-for-pi-71-in-15-minutes

but import com.sap.aii.mappingtool.tf7.rt.Container; shows error , do we need to inlcude any jar file for this :

i am using this module to rename file name (in case of pick and place scenario forwithot IR configuration)

getMessageProperty and setmessageProperty is getting deprecated.(striked off)

strFileName = msg.getMessageProperty("http://sap.com/xi/XI/System/File","FileName");

Regards,

Srinivas
