How Abap proxy works?

[Former Member]

Hi friends,

Can anybody explain me that how actually ABAP proxy works(in both cases clent and server proxy). when shuld we go for proxy.And how proxy seprates business application from technical infrastructure?

If u have any presentation or document on ABAP proxies ,plz send me

Thanks in advance

Hi,

Check this ABAP Proxy Documentation guide:

Thanks.

Hi sanyog,

Thanks for ur reply. still i have one doubt how proxies seprates Business Application logic

from XI connectivity?

Hi,

Proxy objects implement message interfaces from Integration Repository. Proxies are executable interfaces, which converts non-language-specific interface descriptions into WSDL. i.e., you use proxies to implement the actual message exchange that is described in the Integration Builder.

Types of Proxy objects:

You can use message interfaces to create the following proxy objects:

ABAP Proxy objects

JAVA Proxy objects

During the process of ABAP proxy generation, it gets WSDL (Web Service Description Language) description of message interfaces from the Integration Repository by using HTTP communication.

Proxy Generation:

As part of SAP Web AS 6.40

ABAP proxy generation enables you to generate proxies to communicate by using the Web service infrastructure and by using SAP Exchange Infrastructure

ABAP proxies that were generated from message interfaces in the Integration Repository (IR) can be used in both infrastructures.

This means that if none of the Integration Server services are available for a proxy-to-proxy communication scenario in ABAP, you can use a point-to-point connection using the Web service infrastructure instead.

The prerequisites to configure ABAP Proxy include: (landscape dependent)

The business systems should be based on SAP Web AS 6.20 and SAP Web AS 6.20 kernel patch level above 1253

You have installed the XI Add-On in each of these business systems as described in the Installation Guide SAP Exchange Infrastructure 3.0

The business systems and your central Integration Server are maintained in the System Landscape Directory (SLD).

Configuration required on the Business System:

1. Create a HTTP connection in the business system using transaction SM59

Technical Setting:

· Connection Type: H

· Target Host: System name

· Service Number: HTTP Port name

· Path Prefix: /sap/XI/engine/?type=entry

2. Configuration Business system as local Integration Engine.

1. Go to Transaction SXMB_ADM

2. Choose Edit --> Change Global Configuration Data.

3. Select Role of Business System: Application system

4. Corresponding Integration server: dest:// XI_XIR_CONNECTION created in step 1. Dest://XI_XIR_CONNECTION.

5. Under Specific Configuration Data you can specify additional configuration data

Select the relevant category under Specific Configuration Data.

Choose Change Specific Configuration Data.

For ABAP Proxies, Add the following configuration:

1.Category RUNTIME

2.Parameters: IS_URL

3.Current Value: dest://XI_XIR_CONNECTION

I hope this will help you.

Hi Shweta Pandey ,

Proxy generation converts non-language-specific interface descriptions in WSDL into executable interfaces known as Proxies. Depending on the target programming language, you choose one of the following:1. Java Proxies. or 2. ABAP Proxies.

We can interface to XI through proxies. From WAS 6.20, proxy generation feature enables application systems to communicate with XI using proxies. Proxy generation enables you to create proxies in application systems. Proxies encapsulate the creation or parsing of XML messages and the communication with the relevant runtime components required to send or receive the messages.

There are two types of Proxies.

1. Java Proxies.

2. ABAP Proxies.

Java proxies are used when java applications needs to send and receive data and ABAP proxies are used when ABAP applications needs to send and receive data.

Hi

Adapters are part of the Adapter Framework. Adapters provide the technical connectivity to enable the integration of SAP and non-SAP applications through XI’s Integration Engine.Again, Adapters are used for connectivity from and to external systems with XI that cannot communicate via proxies.Adapters are only required in SAP systems older than 6.20 and external systems.

Systems based on 6.20or higher can communicate directly with proxies.

Proxies

The literal definition of a proxy is an object / process authorized to act for another; an agent or a substitute. In simpler terms, proxies in the XI context are objects used to encapsulate the creation (from a sender system) or parsing of XML (at a receiver system) as well as the communication with the relevant runtime components required to send or receive those messages.

Proxies are generated from Message Interface in IR.

The Proxy Runtime controls these objects / processes, and can itself be controlled by the applications it communicates with. The Proxy Runtime currently has the following components available: 1. ABAP Proxy Runtime – Communication using XI or Web Services a. Web Service Runtime 2. Java Proxy Runtime – Communication using XI (J2EE) The objects that the Proxy Runtime then controls are created via Proxy Generation, for both ABAP and Java. In the following sections a ‘client’ proxy is used by an application to send messages outside of the system it resides in (normally to the IS in this context). Conversely, a ‘server’ proxy is used by an application to receive messages from sources outside itself (again, normally the IS in this context).

Proxies are interfaces which will get executed in the application system. They can be created only in the system from message interfaces using the proxy generation functions. You can use proxies for systems with WAS >=6.20

XI will communicate in native language with SAP systems via proxies. Proxies uses XML - SOAP based communication for both ABAP and Java Proxies.

mainly we go for proxies for adapters less communicaton there

Client Proxy: Proxies created out of Outbound message Interfaces.Here XI is receiving some information and is

acting as a client.

Server Proxy : Proxies created out of Inbound message Interfaces.Here XI sends the information to some other system acting as the Server.

we can create the ABAP proxy in ABAP workbench.

Use

Using ABAP the proxy generation function you can generate ABAP proxy objects to an SAP system from an interface description in the SAP Exchange Infrastructure Integration Repository.

Prerequisites

ABAP proxy objects can only be generated for SAP systems that are based on SAP Web Application Server 6.40.

The proxy generation retrieves the WSDL description of the interface from the Integration Repository using HTTP. The address of the appropriate server is taken from the exchange profile (parameters 1, 2, and 3 u2013 see below). Queries to the Repository are subject to authentication. The user and password for these queries are also taken from here (parameters 5 and 6). Information used to navigate from the ABAP Proxy Generation to the initial page of the Integration Builder is also taken from the exchange profile (parameters 1, 2, and 4).
