coll.appl.room.roomobject_api.jar download problem!! Where can I get it?

Hi All,

I need the coll.appl.room.roomobject_api.jar file . I am trying to download it from the KM Portal. But after downloading it I found that the jar file contains only the meta inf file but the required class files are not there. So any one of you tell me what is actually that problem is?

will reward max pint for helpful answer.

Thanks and Regards
