Hi Bose ,

1.J2SE Adapter Engine is used to connect SAP Exchange Infrastructure (XI) to external systems. It uses the various xi adapters so that XML and HTTP-based messages can be converted to the specific protocol and format required by such systems.

Depending on the configuration, the adapters can be used to do the following:

a. Exchange data with external systems using a file interface or an FTP server (file/FTP adapter)

b. Communicate with messaging systems using the JMS API (JMS adapter)

c. Access databases using JDBC (JDBC adapter)

d. Communicate with clients and providers of Web Services using SOAP (SOAP adapter)

2.The Plain J2SE Adapter Engine is only supported for compatibility reasons. It hosts only a subset of the adapter functionality and has fewer security features. You should only use the Plain J2SE Adapter Engine if it is a precondition in your environment.

J2SE Adapter engine is kept outside because the connection data is kept locally. The adapters of the Plain J2SE Adapter Engine are configured locally and not in the Integration Directory. Exchanged messages are also stored directly in the file system. Therefore, ensure that only the operating system user, who has started and therefore owns the adapter engine process, can read the property files and has access to the directories used for message exchange.

The Plain J2SE Adapter Engine has a separate user and password management, which is not integrated into the overall SAP NetWeaver user administration..All configuration data for the Plain J2SE Adapter Engine is maintained in flat property files.

The file for the engine administration data itself is located in the following directory:

<installation directory>/tech_adapter/BaseConfiguration

The file for the adapter configuration data is located in the following directory:

<installation directory>/tech_adapter/Configuration

*Pls: Reward points if helpful*
