How can SAP tRFC server tell client through JCo that function has been carried out?

Question

SAPs "Transactional RFC Technical Description" document (release 4.0, see http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/ee6bca90-0201-0010-5792-d9693e2eac83?QuickLink=index&overridelayout=true ) says in section Transactional RFC on page 6: "Finally, the server tells the client, that the function has been carried out and the client acknowledges this.".

How can the server tell this to the client when the server communicates with the client through JCo (Java Connector)?

Release 4.0 is quite old - be sure to always use the recent documentation.

From what I can see, there's no way to hand the result of the tRFC call back to the server. tRFC calls might be placed in a (local or remote) queue and executed later. See http://help.sap.com/saphelp_nw04/helpdata/en/f0/02a63b9bb3e035e10000000a114084/frameset.htm for information on how to monitor tRFC calls.
