Hi,

here is some xtract from sap-help

interface:

You use a message interface to describe a platform-independent or programming-language-independent interface, which you want to use to exchange messages between application components using SAP Exchange Infrastructure. Depending on the communication parameters defined for a message interface, it can either have the task of sending a request (outbound) or receiving a request (inbound). Assigning an outbound interface to an inbound interface enables multiple communication parties to exchange messages with each other (see also: Communication Parties (Case Examples)). The following connections are possible for message interfaces:

· A message interface with another message interface

· A message interface with an imported interface

· A message interface with an interface configured by an adapter

Adapter:

Purpose

Adapters enable the Integration Engine and the Partner Connectivity Kit (PCK) to communicate with different applications.

Implementation Considerations

You only require an adapter to communicate with SAP systems older than Release 6.20 and with external systems. A direct system connection using proxies and without additional adapters is supported for SAP systems that are based on SAP Web Application Server 6.20 or higher.

Features

Adapters connect the Integration Engine to SAP legacy systems, as well as to external systems.

In this way, adapters integrate existing SAP components with SAP Exchange Infrastructure, for example. In the process, XML and HTTP-based documents are converted to IDocs (IDoc adapter) and RFCs (RFC adapter) and the other way around. This enables you to integrate your existing SAP infrastructure with the new SAP infrastructure, which is based on system integration and the exchange of XML messages.

The plain HTTP adapter gives application systems the option of communicating with the Integration Engine and exchanging business data in a simple format, using an HTTP connection.

Furthermore, the J2EE-based Adapter Engine provides you with various adapters that you can use to connect external systems to your Integration Engine. You can use these adapters to convert XML and HTTP-based messages to the specific protocols and formats of the respective external systems and the other way around. You can specify generic modules for adapters in the Adapter Engine in the module processor. These modules give the adapters additional functions. Modules describes the modules shipped by SAP.

For more information about developing modules, see Adapter and Module Development. This section also provides information about how to create new adapters.

In addition to the J2EE-based Adapter Engine, you can also use the plain J2SE-based Adapter Engine.
