Where to start to build an application to send/receive XML file from/to XI?

[Former Member]

Hello.

I am very new to XI technology.

I have looked various documents to get familiar with the technology and terms related to it.

I am trying to build a stand-alone applcation to send/recevie XML from/to XI. I need some clue where i should start to do. If there is a sample code about how I can connect to XI or way to receive a message, that would be very helpful to me.

Thanks.

Vishnu and Priyanka,

Thank you for your postings. Those links are very helpful to understand about XI in more detail.

Actually, what I want to do is to implement a some kind of listener to receive messages from XI as well as a sender to post messages to XI.

What i understand is XI is a kind of middleware to communicate to SAP. I have a sample code of communicating to SAP directly, but not to XI. Is there any simple code available to handle a connection to XI?

Hi Kevin,

Hope u had a nice learning. Yes as you said XI stands as a middleware. It can communicate with ANY to ANY system, not only with SAP.

>>>>I want to do is to implement a some kind of listener

XI provides something called adapters for various kinds of system.

>>>>to receive messages from XI as well as a sender to post messages to XI.

As said above, you have to use Reciever & Sender adapters, of various types (as per your systems).

you can also choose the mode of the transactions (or sometimes forced based on the scenario).

Other than these adapters XI has "Proxies", to communicate with certain version of SAP systems

>>>>>Is there any simple code available to handle a connection to XI?

This is taken care when u set-up a flow in XI. (but though its adapters/proxies, communication channels etc)

It is not very clear ("simple code"), what exactly is to be achieved here, but as said above, Proxy may be more or less like something you expect, but it is only for SAP systems.

Hope this helps

You can try out a simple file to file scenario...this blog will help you in this:

Once you go through these links and are a bit aware what all XI objects do, you can try a simple "File to File Scenario" which would help you to understand XI objects in a much better manner.

For help on this scenario go through this blog it is in two parts thus i am providing both links below:
