How Can I make Use of XI

Question

Hi Friends,
I am a kind of newbie in to this world of XI,
I have a  quick question,Before stepping into the question please look in to my Existing process.
I have a J2EE product,
which needs the business data from differant versions of R/3 systems (for example 3.1,4.3,4.6c)
and some other systems as well(say people soft and few other legacy systems),
If I am asked to deploy my J2EE product at a ABC client site who has already the above environment(SAP and other systems),
The scenario would be :
1.Extracting the needed data from all the business environments of the client ABC(SAP 3.1,4.3,4.6c, People soft, Legacy)
2.Converting them in to the flat files and placing in FTP
3.Communicating thru my product to the FTP
4 Loading in to the database which is compatible with my product(say Oracle,SQL Server,DB2...etc)
Currently for Extracting the data from SAP Systems,
I am writing the ABAP programs to extract the data from the client systems,
which will create the needed flat files in FTP,
But In case of the extraction other than SAP systems,
Client ABC will be giving me the needed data from the other business systems in the required flat file format,
Step 4 will be handled by my J2EE product when all the needed filed are ready in the specified FTP location.
Now my question is,
How can I make use of Exchange Infrastructure process integration methodology in my current business process,
It would be great if some one can propose in enhancing the process by making use of XI,
Thanks in Advance,I look forward for a quick response.
Regards,
Sanjeev.

Hi,
<i>I am looking for a way where I can directly write the logic with in XI for extracting the data from SAP and other systems and moving in to my oracle database,</i>
>>>Think XI is an EAI tool. So you need to write a logic in the SAP systems to push the data into XI. Or even you can make XI to poll the data from SAP.
<i>Here the senders should be as
Sender 1:SAP3.1
Sender 2:SAP4.3
sender 3:SAP4.6
Sender 4:People soft
sender 5:Legacy1
sender 6:legacy2
Reciever should be a single Oracle Database on which my j2ee product will be sitting.</i>
Ideally you can have 3 entries for all 3 SAP systems in SLD.
For PeopleSoft system,Legacy1,Legacy2 different SLD entries.. SO it is something like you need to have Business system for each Systems.
Then I suggest, you have already ABAP programs in place, you can use this and you can call proxy from these programs. So that you can avoid doing some of the developments. But inorder to process on Proxy you need to have SAP WAS6.40 and above or SAP WAS 6.20 with add-ins.
If this is not feasible then you need to eithe go with Idoc/RFC sturctures from the R/3 sides.

First try to lay out the system landscape design with message exchange format etc.
Then it is possible to do the design easily.
For e.g from Peoplesoft you will get the data in file format. That time you can go with File->XI->Data Base scenario.
Hope this helps,
