Java proxies in PI 7.1 - Requesting ACKs

[Former Member]

Hi,

I'm trying to build an scenario in which an external Java application (java proxy) sends a message to PI. PI will send a file through FTP to the target system, and the technical ACK of the adapter has to be returned to the java proxy (and then will do something accordingly).

In this [blog|http://www.sdn.sap.com/irj/scn/weblogs?blog=/pub/wlg/3875] [original link is broken] [original link is broken] [original link is broken]; Michal explains how to request the ACK to the file adapter from a ccBPM, and he also explains that you can request these ACKs from proxies (and also idocs through idx_noale).

The difficult part for me is understanding the new Java proxy model in PI 7.1. With the old model you could request ACKs this [way|http://help.sap.com/saphelp_nwpi71/helpdata/en/55/65c844539349e9b1450581ab44a5e6/content.htm]. But now, when clicking on "Tools-Java proxy generation" from the ESR, it says that the old model will not be supported in later releases. That means that I should not use the step by step guides and weblogs available in SDN for java proxies, and instead use the [new model|http://help.sap.com/saphelp_nwpi71/helpdata/en/45/100c6be9f87201e10000000a155369/frameset.htm].

That's what I think but I'm not sure. And then, what would be the way to request ACKs to PI using this new model for java proxies?

Thanks

I've just found this [guide|http://www.sdn.sap.com/irj/scn/events?rid=/library/uuid/40a0868a-9d40-2b10-8cb4-8e0c53b56655&overridelayout=true] in SDN with these quotes:

- New Proxies have to be created in NetWeaver Developer Studio

- Some JPR 3.0 classes are not available for JEE 5-based proxies, for example

com.sap.aii.proxy.xiruntiume.core.MessageSpecifier

- XI 3.0 proxy-specific features (like acknowledgements) cannot be used

So it seems that the new Java proxies do not allow acknowledgements.
