Hi, Krishna:

The concept of proxy and mapping is different.

Proxy:

=======

As you probably know that XI is middle ware, it bridges messages from sending system to receiving sytem.

We call it application system.

If the application is SAP system, the connection between application and XI server can be achieved by

1. IDOC

2. RFC

3. ABAP Proxy

There are other connection too, like file, SOAP etc...usually above three methods have been used commonly

Similarly, If the application system is Java System, then Java Proxy can be used for the connection.

Mapping:

=======

Transformation of the message in XI are based on:

1. Message Mapping - Graphical Mapping tool + User Defined function (Java Function)

2. Java Mapping

3. ABAP Mapping

4. XSLT Mapping

Usually Message Mapping is always first choice, the others, It depends on company's coding standard to choose which type of mapping.

Different mappings has Pros and Cons.

Hope it helps

hi..

Java Mapping:

It is a mapping program written in Java which implements a specific interface of the mapping API which transforms any document into into any required format.

Some of the transformations can be from,

• XML to XML

• XML to Text

• XML to HTML

• Text to XML

• HTML to XML

Sometimes with graphical mapping it is difficult or it may seem impossible to produce required output; for example

When the required output is other than XML like Text, Html or XHTML

When the data is to be extracted from input which is in text format

When default namespace coming from graphical mapping is to be changed as per requirements

When data is to be filtered, sorted or grouped based on certain fields (considering File as source)

When a flat file is to be converted to a hierarchical structure (IDoc to File or File to Idoc)

Chk this link for the further information.

Java Proxy.

Using the Java proxy generation function, you can generate Java classes or Java proxy objects from the interface description in the Integration Repository. Using these objects, you can then implement sender and receiver applications in Java; the proxy objects establish the connection to the Integration Server by using the Java proxy runtime.

Hi,

java mapping,abap mapping are different types of mapping provided by XI. Some times based opn the business requirement u need to go for the specific mapping and if ur business requirement can not be achieved by graphical mapping then u have to opt for the other options like java,abap or XSLT.

Now coming to proxy part:

two types of proxies ABAP and JAva

When there is a scenario to interact with R3 system u can go with either ABAp proxies where u need to send data from SAP R3 system to some legacy system and vice versa.

Please look at the below link for more details:

for java proxies
