Prior to the introduction of the J2EE Connector Architecture (JCA) there was no standardized method to integrate enterprise systems with legacy data. However, with the advent of JCA, and using Attachmate's J2EE-compliant resource adapters, you are able to access host data and integrate with supported application servers. Attachmate supports four application servers: BEA WebLogic, IBM Websphere, Oracle 9i AS, and Sun's SunOne AS7.
The Synapta Services Builder provide two JCA-compliant resource adapters; the JCA adapter for Weblogic, which uses BEA WLI extensions, and the J2EE connector, which is a generic resource adapter implementing the JCA Common Client Interface (CCI). The JCA adapter for WebLogic uses Web services generated in the design-time component, while J2EE session EJBs and connectors are managed and deployed to selected application servers through your Synapta Services Builder management component, MCS.
CCI is a set of interfaces, which provides a framework for basic interaction with resource adapters.

| built to JCA 1.0 specification | built to JCA 1.0 specification |
| complies to CCI standard | provides BEA WLI extensions |
| available from MCS | configured in the design-time component |
Session EJBs are efficient, lightweight, Java beans that work well in J2EE environments. When an EJB is generated a JAR file is created, along with a connector RAR file as part of an enterprise application, and then deployed to your selected application server on a per project basis. Projects can contain multiple tasks.
Characteristics are:
Synapta Services Builder encapsulate legacy assets for reuse in WebLogic Integration (WLI) as a J2EE Connector Architecture (JCA) resource adapter via a Synapta Services Builder application view that was built using the WLI Application Developer Kit (ADK). The JCA adapter for WebLogic is installed on a computer that is running the BEA WebLogic application server and the WebLogic Integration component.
Using the Task Builder (design component) you can map host applications and create task files containing one or more tasks. These tasks are exposed as XML-based services which can be accessed within the BEA Application View interface for integration with custom applications.
