HTTP-FILE synchronous scenario

[PratibhaK]

Hi,

I want to configure a Http to file synchronous scenario.

Message will be sent through the HTTP test tool. I have selected BestEffort as the QoS.

We do not want to use the repository objects.

Sample file say(<tag>this is a sample file</tag>) will be sent through HTTP test tool.

This file should be received by the File Receiver channel and dumped on the FTP.

In response, a file from some other folder on FTP should be sent.

How can this be achieved?

Regards,

Pratibha.

File adapter does not support sync scenarios..so you have to use BPM for this. elase devide your requirement in to two individual interfaces...

Hi,

Even if the BPM is used, will it be possible to pick some file at a location on FTP and send as a response?

If yes, please explain..

Hi Pratibha,

In that case the BP has to wait for the other file with a second receive step. The two messages need to be correlated with a unique number. The synchronous response from the BP will take a while.

Hi Udo,

Can you throw some more light on the steps and process to be followed?

I am very much new to BPM..

Thanks,

Pratibha.

Hi Pratibha,

the standard sap help side is here very good

[Integration Processes (ccBPM)|http://help.sap.com/saphelp_nw2004s/helpdata/en/3c/831620a4f1044dba38b370f77835cc/content.htm]

You need a receive step (synchronous) for for your http request. For this you need 3 abstract interfaces: 1 synchr IF, 1 async for request container, 1 async for resp container. You need to correlate with a unique number which the http sender has to send (f.e. date/time stamp)

Next may be a transformation (mapping) but not required.

Then a async send step to send the file.

The response file need to be created, the corresponding adapter should have a short poll intervall. The response file need to send the unique id as well.

The BP correlates the second receive step, next you can - like before optional - execute a transformation step.

Finally u close the sync/async bridge and send the response back. This will take assumedly a minute or more.

The whole design is may be not sufficient. Better ask if the requierments are changeable.

Hi Pratibha,

synchronouns request/response is not possible as file / ftp is asynchronous.

You can instead have 2 asynchronous message http->ftp and ftp->http.

You need at least some dummy repository objects.
