The Oracle JCA Framework provides pluggability for adapters that comply to the J2EE Java Connector Architecture, version 1.5. That is, any adapter used with the Oracle JCA Framework must fulfill the requirements documented in the JCA 1.5 specification (see also JSR-112, J2EE Connector Architecture 1.5 - Final Release).
Note:
The Oracle JCA Framework implements a lightweight JCA 1.5 container, which enables dynamic (code-driven) deployment of inbound endpoints (activations). This does mean a small disadvantage in precluding support for JCA 1.5 Transaction Inflow (that is, support for XATerminator support).
