Hi SDN Exports,

diff b/w these two and it's advantages?

thanks in advance....

Hi,

proxies are adapterless communication method in XI

ABAP proxies are create in R3,ERP backend

and java proxies are created in XI (java WAS)

prosiex are simple objects that allow you to send (or receive)

messages to (or from XI) (so you can fill the code - either java

or abap and call the method of those objects ) and the messages

will be sent

Hi

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:

- <u><i>ABAP proxy generation</i></u> is part of the 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 required for a proxy-to-proxy communication scenario in ABAP, you can use a point-to-point connection using the Web service infrastructure instead.

- <u><i>Java proxy generation</i></u> in the Integration Builder (Design) generates proxies from message interfaces in the Integration Repository. Java proxy generation packs the proxy objects in a Jar file, which you can save locally. You use the generated classes in J2EE applications on the SAP J2EE Engine.

Hi Sudarshan,

The aim of proxy communication is to bypass the adapter engine thus providing an adapterless communication. With proxy you save on performance over using adapters and also it reduces complexity.

Proxies support both Synchronous and Async. Connectivity - ALE/IDOC is only Async. Proxies don't use standard IDOCS, but what you decide to use in the proxy def. on SAP side.

Proxies are only supported on WAS 6.20 onwards.
