JAVA is strategic to SAP

• Over the past twelve months SAP has heavily
  focused on developing its technology
• Two main areas of focus are
• 1. Exposing SAP functionality through the Java
  Connector.
• 2. Creating a J2EE run time engine within the
  underlying SAP technical layer.

SAP Java Connector
SAP developed and released the SAP JAVA Connector
(JCO) 2.0.4 The SAP Java Connector (SAP JCo) is
a toolkit that allows a Java application to
communicate with any SAP System. It combines an
easy to use API with unprecedented flexibility
and performance. The package supports both Java
to SAP System as well as SAP System to Java
calls. Features include

• High performance JNI-based RFC middleware.
• Supports R/3 3.1I and higher (and other mySAP
  Components that have BAPIs or RFCs).
• Supports synchronous, transactional (important
  for IDocs), and queued RFC.
• SAP Java IDoc Class Library Beta 1 available for
  download. It provides an API which helps
  navigating, reading, filling, and modifying Idocs
• Supports client pooling (good for web servers).
• Multi-platform
• Easy to install and deploy.

Integration and Connectivity Based onSAP Java
Connector

• Enables communication between existing SAP System
  and Java application
• Supports inbound (Java calls ABAP) as well as
  outbound (ABAP calls Java) communication
• Hides all difficult parts like code pages, data
  type conversions, connection pooling, etc. from
  the programmer
• Consistent and easy-to-learn class design and API

SAP Web Application Server

• The SAP Web Application Server is the underlying
  technology of almost all solutions of mySAP.com.
  This is the new name for what has been referred
  to previously as SAP Basis. The name reflects the
  significant technology changes introduced with
  the latest release of the SAP Web Application
  Server e.g. in the following areas
• Openness Standardization
• Web Development
• Reliability
• Scalability
• Flexibility

SAP Web Application Server

• The SAP Web Application Server is a J2EE
  compliant application server, i.e. it supports
  Servlets, Java Server Pages (JSP), Java naming
  and directory interfaces (JNDI), Enterprise Java
  Beans (EJB) and all other services listed in the
  J2EE specification. Some of the key functions of
  the new SAP Web Application Server include
• 1. The Web Web Application Server is an
  independant upgrade to an SAP application
  upgrade.
• 2. All of the traditional SAP Basis kernel
  functions such as Computer Centre Management
  System, Load Balancing, Security, workflow etc
  still apply.
• 3. SAP will deliver an open IDE for J2EE
  development for the SAP Web Application Server on
  top of the Eclipse platform.
• 4. All of the devlopment relation functions of
  the basis kernel can be utilised for the JAVA
  flavour. For example Transport Management
  System, Data dictionary, security etc.
