Support for the Java Connector Architecture, which provides a standard
for connecting the J2EE platform to legacy enterprise information
systems (EIS), such as ERP systems, database systems, and legacy
applications not written in Java.
Package Specification
Users who want to run JE within a J2EE Application Server can use the
JCA Resource Adapter to connect to JE through a standard API. The JE
Resource Adapter supports all three J2EE application server
transaction types:
- No transaction.
- Local transactions.
- XA transactions.
JCA also includes the Java Transaction API (JTA), which means that JE
supports 2 phase commit (XA). Therefore, JE can participate
in distributed transactions managed by either a J2EE server or
the applications direct use of the JTA API.
