In the book "Professional EJB" (Wrox) both can be found:
- _J2EE_ Connector _Architecture_ (page 830 ...)
- _Java_ Connector _API_ (p. 357 ...)
- JCA = "Java Connector API" (in the index)

In another book, Paul Allen + Joseph Bambara "Sun Certified Enterprise Architect for J2EE Study guide" I found:
- JCA = _Java_ Connector _Architecure_ (indes + p. 309 .. 334)

In java.sun.com I found:
- JCA = _J2EE_ Connector _Architecture_ (JCA) at http://java.sun.com/j2ee/connector/giga/RPA-112000-00018.html
- "... using _Java_ Connector Architecture ... using _J2EE_ Connector Architecture (JCA)" (i.e. two different defs within one single article) at http://developers.sun.com/sw/building/codesamples/integration_jca.html

- SAP provides "Java Connectors".


So we have at least the following combinations:
- _J2EE_ C. _Architecture_
- _Java_ C. _Architecure_
- _Java_ C. _API_

That is a pritty confusing mix that I tried to get accustomed to, but I can not really.

Is it really just a matter of naming?
Has "JCA" really been redefined from "Java Connector API" to "J2EE Connector Architecture"?

Does JCA require J[2]EE or just J[2]SE?

Is it a matter of V. 1.0 vs. higher versions?

Thomas.
