Use of Proxies(both java and abap)

[former_member187437]

Hi all,

I would like to know when to use Proxies and in what way its adavantageous.

HI Aarthi

Proxies are nothing but a mechanism to shift the application logic from the XI server onto the sender or reciever system so as to reduce the effort on the side of XI.Depending upon where the proxies are generated ,it is differentiated as client proxy ( sender ) and server proxy ( receiver ) .In R3 system having WAS 6.2 and above its already has an inbuilt small IE so the proxy generation is favoured and possilbe,for more on this please go thru the following links

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.

The biggest advantage of the proxy is that it always by passes the Adapter Engine and will directly interact with the application system and Integration engine - so it will and should give us a better performance.

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. The Proxy Runtime controls these objects / processes, and can itself be controlled by the applications it communicates with.

The Proxy currently has the following components available:

1. ABAP Proxy – Communication using XI or Web Services

2. Java Proxy– Communication using XI (J2EE)

Hi,

The use of proxy/adapter is to convert the message (any format) to the xml format which is then be processed by the integration server. We should use the proxy, When our SAP system version is 6.20 or higher.

In case when you want to integrate the BI server to the R/3 or any legacy then you can use proxy at the BI end.

Not only BI but all the SAP's new dimention products like SCM, SRM etc are communicating with other systems using proxy.

In short Proxy is the new programming pradigm for the next generation SAP applications

hi

check the following link ....

they discussed briefly.....

hi

Go through this

Proxies communicate with the XI server by means of native SOAP calls over HTTP .RFC does not, so you have to convert from SOAP to RFC calls and vice versa. So XML conversion is required.

ABAP Proxies uses Webservice and Http Protocols. And if you use RFC it is mainly meant for Sync. call. But Proxies is used for both Sync and Async.

If you use ABAP Proxy , you can reduce the overhead calling the function again and again.

/people/ravikumar.allampallam/blog/2005/03/14/abap-proxies-in-xiclient-proxy - ABAP Client Proxy

If u generate proxy for outbound interface then its client proxy and for inbound interface its server proxy.

In client proxy u can call the method to send messages but u can't modify it but in server proxy its possible to write a user code within the method to execute proxy.

CLIENT PROXY:

A WSDL description from a UDDI server (or an Internet page) is usually used to make a service executable in the Internet and to describe the interface of this service. You require a client proxy and not a server proxy to call this service by using the Web service infrastructure.

SERVER PROXY:

You can only generate ABAP server proxies from a WSDL description if they originate in the Integration Repository.You can also generate server proxies for Java and client proxies for ABAP from message interfaces.

HI

this blog should answer your question
