Call another Message Interface from Java Mapping

[Former Member]

Hi Gurus!!

I have designed a Java Mapping that does a Socket Connection. Before send the response of the Java Mapping, I have to send information to our SAP System.

I have see in a blog that I can call a RFC from the Java Mapping, but my doubt is, can I call another Message Interface designed on XI?

Thanks and regards,

That's tricky, since the proper way of doing it would be through BPM.

Anyway, if you expose your XI interface as a WebService (Soap sender cc) you could access it through Mapping Lookup (lookup works for RFC, DB and Soap lookups). Check https://help.sap.com/javadocs/NW04S/current/pi/index.html

But be aware that Mapping Lookup API is not intended for inserts/updates (since it doesn't contain any transacational handling), just mere lookups (selects in tables), so I'm not sure it is the best approach for your case.

Hi Henrique,

I have to update a table on SAP, I'm thinking to use a RFC that updates the table.

My problem is that I can´t use Java Proxies because they are not processed in parallel way, then I have to use Java Mapping to get socket connections.

HI

As per my understanding of your requirement. If you need to send the response 1 to SAP in single thread then you need to do RFC from Java Mapping.

Is there another way to do a Socket Connection using XI apart from Java Proxies and Java Mapping?

Can you explain your end to end scenario?

Hi Prateek,

This is an explanation of my scenario (SAP-XI-ExternalServer).

From SAP, we send a request to XI (ABAP Proxy), on a Java Mapping we send this message to the external server using the TCP/IP protocol. The external server sends 2 responses. With the firsr response, I have to update a table on SAP, and the second response is the response of the Java Mapping, that is threated in a BPM. My problem is with the first response.

why don't use BPM?

Hi Anand,

My Java Mapping is in a BPM, but I need to do the process with a Socket Connection opened and I have the socket connection opened in the Java Mapping. When the process is out of the Java Mapping I loss the control of the socket connection.

Hope have seen clear enough.

Manuel.

in the same http connection you have to messages being transmitted?

Or are they in different connections?

Hi,

An ideal design would be redesign your output message of the Javamaping and bring all data (both response), I am sure you can get that. Then continue processing within BPM.

If that is not called for, use a JCO to call the RFC of our first response. You will lose the monitoring features here!!!.

They must be transmitted on the same connection. This is my "problem".

Thanks and regards,
