Define Web Service - Send Asynchronous Message

[Former Member]

Hi All,

I have to send an asynchronous message from a java web application to XI. For this I tried to used the Define Web Service option in XI. However the documentation says that this tool can be used only for Synchronous interfaces. Is this the case even now? What would be an alternate approach to accomplish this?

Thanks,

Hi,

As explained above , no need to have the webservice only in the case of Sync communication , you can also achieve this by way of generating the WSDL from ID -- tools and added the Quality of service = EO.

Please see the below links to get more details

Hi,

You can Generate WSDL's for Asynchronous Interfaces also. It is not needed that you Select only a Synchronous Interface.

While generating the WSDL in the Integration Directory using Tools --> Defined Webservice, you will be able to select your Outbounf Asynch interface also.

Just remember that while defining the WSDL Url you will need to append the following parameter to the end of the url,

<b>&QualityOfService=ExactlyOnce</b>

Many Thanks Bhavesh, Could you please suggest some blogs or other resources which talks more about this?

Also, Which is a better option? Provide a URL by ourselves or use the Propose URL feature? I assume that I need to add &QualityOfService=ExactlyOnce at the end of the proposed URL. Is this right?

To download this WSDL from a remote system what URL can we use?

Thanks,

Sandeep

Sandeep,

Provide URL and Propose URL are a bit different

1. When you provide URL as pointed in the How to Guide - How to use SOAP Adapter, the SOAP message is sent to the Adapter Engine and the sender SOAP adapter forwards it to the Integration Engine. The port used will be the J2EE engine port.

This is discusses in the How to Guide. - How to use SOAP adapter.

2. The Propose URL is used when you want to send the SOAP message by passing the Adapter Engine directly to the Integration Engine. In this case you do not need a Sender SOAP adapter and the port used is the HTTP port.

This option is discusses in this blog by Stefan Grube,

Let me know if you need mofre inputs.

Once again thanks to you Bhavesh. I have one more question.

How do I provide the userName and password while I consume the web service. I'm sending the message from a java application. Can the userName and password be also embedded in the URL?

Thanks,

Sandeep

Sandeep,

If you use the blog by stefan grube , then you can append the user id and password to the URL as,

http://serverurl:httpport/sap/xi/engine?type=entry&version=3.0&Sender.Service=Stefan&Interface=http%...;
