Hi All,
I would like to know the difference between J2EE and J2SE adapter engines used in XI/PI. When do we go for J2SE and pros and cons of them.
Regards,
Praveen Kumar
J2SE adapters were used in earlier versions of XI (XI2.0)
Later J2EE adapters came into pictures XI 3.0 onwards
In XI3.0 J2SE adapters are retained to support the customers who implemented J2SE adapters
Its better to opt fot J2EE adpters

Hi!
J2SE engine is mainly used in the XI 2.0 and later on while in XI 3.0 release SAP introduced J2EE engine for maintain adaters centrally.
You use the plain J2SE Adapter Engine to connect SAP Exchange Infrastructure (XI) to external systems. Using the various adapters in the Adapter Engine, XML and HTTP-based messages can be converted to the specific protocol and format required by such systems, and the other way around.
In principle, you connect external systems to SAP XI using the adapters that are installed centrally or non-centrally in the Adapter Engine (J2EE). You configure this centrally by using the Integration Directory. Additional functions include an enhanced monitoring and increased downtime security due to the J2EE-based cluster operation of the Adapter Engine.
Plse gi through the below links here you can get some information ::

_Note:: _ Also by using J2EE engine u can sent huge messages in very less time and also you can configure adapters at different different business requirements and also u can use more adater modules in orede to achive typical requiremetns with ease and fast transfer.

HI praveen,
The J2SE Adapter Engine differs from the J2EE Adapter Engine. It is a standalone
tool that runs on its own Java Virtual Machine. It can be installed on
any business system and is delivered with XI 2.0 (as the only Adapter
Engine), as well as with XI 3.0 (in addition to the J2EE Adapter Engine and
the PCK). The handling and the functionality in XI 3.0 is - apart from a few
exceptions u2013 exactly the same

adding to it, not only because of XI 2.0 but also because in case your current platform (OS) is not able to support the J2EE engine (basically because the platform is not compatible with the J2EE 'norms') you will go for the J2SE engine.
from help;
The plain J2SE Adapter Engine provides some of these adapters as a standalone version with restricted functions for operating systems that do not support the SAP J2EE server, but that do have JDK 1.3.1 or higher. Therefore, you should only use the plain J2SE Adapter Engine if the platform prerequisites do not allow you to use the J2EE-based Adapter Engine.
