FIleclient to XI connection details :SRM Interaction

Question

Dear all,
           I am struck up in proposing a solution to the client.
Existing Flow.
         In the existing Topology, the suppliers are interacting with Commerce one using documents in XCVL  format.The Suppliers connect the Commerce one site using FIleCLient for sending and receiving the documents.
The Fileclient automatically picks up the document from the folder and send to Commerce one from their based on Buyers details is posts the document in Buyers system(SRM).Vice versa, when ever their is document laying in commerce one , it picks from that place and posts in FIle client directory using HTTPS.
FileCLient:
This piece of GUI software was written in JAVA using Swings.Every supplier has to install locally this software on their servers .It has lot of directories/sub directories.In one of the folder called Properties they are configuring the Commerce one site details, Buyers details ,Login/pwd...
To Propose:
  Now we are shifting the business process from Commerce one to XI3.0 sp15.
Now the suppliers need to connect to XI for sending and receiving the documents using HTTPS.where and How to make
the necessary changes in FileCLient software so that the suppliers can run their business using existing one.
Can any one guide me.
Thanks

Answer 1

its not that an IDOC is created when you activate change pointer,basically an IDOC will be created as soon as any changes are made to the underlyin table(s).
and your requirement is exactly the same,you just need to figure out which IDOC you want to use,then activate the change pointers for that IDOC and schedule the report i said in earlier reply,once all this has been IDOC's will be distributed (to XI) as soon as any change has been made.
secondly proxy is a different concept,we use proxy if there is no standard IDOC or RFC or if performance is a big constraint.in proxy you need to schedule ABAP report which will send the updated data
you have to use either IDOC or Proxy depending upon your requirement.
my suggestion would be to use IDOC if the data load is not too much and you already have an existing IDOC to serve your purpose,if you don't have an IDOC or performance is a huge issue then write a ABAP proxy and send data.
Thanx
