SOAP <-> PI <-> SOAP with Attachments

[Former Member]

Hello Experts

I have a scenario, where I send a DocumentName in a request to PI. PI makes a webservice call, retrieves the document (.pdf) and sends it back to requester. I just wanted to confirm, if I should be using Java Mapping anywhere to read the .pdf file before sending it to requester?

Also, would using a HTTP GET or a REST adapter be a good idea?

Any pointers would be greatly appreciated.

Thanks

Jaya

Hi Jaya - Nice to see you here

I think you can use the SOAP axis framework to get the file and send it back to requester.

Have a look at the below blog if it helps..

Thanks Amit and Hareesh for your inputs. My scenario is working fine.

1. However the name in the attachments received from target system are not being retained. I used the code snippet from blog: in my response mapping (Sys2 -> Sys1) and it doesn't seem to help. Any pointers?

Thanks Hareesh (It was nice to see you here ) and Amit and my apologies for not getting back sooner.

There is a small change in requirement at my end. it would be SOAP <-> PI <-> REST (with attachments). REST Call: SAP PI receives a .pdf file in response and SAP PI will need to send the same file as-is (reading the file in PI is not required) to source system. Need your pointers on REST call with attachments and how this could be handled.

Thanks in advance.

Hello,

U can use pointers provided above, but do remember that in PI there is a limitation in the length of a URL which u can create for calling rest web services using soap axis protocol.

Regarding passing attachments, i think my reply would still be valid (but u have to check the same)

Thanks

Hello,

>>PI makes a webservice call, retrieves the document (.pdf) and sends it back to requester

How WS is sending pdf file? as an attachment?

>>I just wanted to confirm, if I should be using Java Mapping anywhere to read the .pdf file before sending it to requester?

I think while sending response to sender system either using JM or UDF u can read that pdf attachment (coming from receiver system) and set the same in ur response (never tried in sync scenarios but i think it will work).

@Hareesh,

I don't think Jaya can use ur approach, becoz Michal's bog clearly mentioned that this kind of approach will be helpful in case of u have static request and i believe document number is dynamic. In addition to that, i am not sure how above approach can be implemented on a receiver side?

Thanks

Hi Amit  -

My intension in sharing the above blog was that Axis framework supports HTTP get and the same can be found in the SAP note #1039369 - FAQ XI Axis Adapter

27. Can I call the target service with HTTP GET?

The provided blog has another link which explains how to retrieve the file from a webpage
