Special Services of the Proxy Runtime 

Use

Using the documentation above, and a correspondingly configured connection, you are now able to exchange messages using the Exchange Infrastructure from the perspective of the proxy runtime (the interfaces used to exchange messages are maintained in the Integration Directory and not in the application program). However, there are other services that are required in particular application scenarios. These services are described below.

Features

You can also influence the runtime response in the application program by using methods of the messageSpecifier interface:

·        You can call payloads in the proxy runtime after a client proxy has been called, or while a server proxy is being called, for example, because you want to archive the payloads. See: Calling the Payload.

·        Instead of determining the receiver using routing, you can specify the (B2B) receiver for the client proxy directly. See: Setting the Receiver.

·        You can append attachments to the message at the sender, which you can then call at the receiver (and the other way around). See: Attachments.

·        You can query the message ID of sent and received messages. See: MessageSpecifier Interface.

Furthermore, administrators on the receiver side can allocate authorizations for receiving messages by assigning the corresponding security roles to a J2EE user and then specifying this user in the Integration Directory. For more information about authorization checking and creating users on the SAP J2EE engine, see the Configuration Guide.
