<span class="emphasis"><em>JCA</em></span> is the <span class="emphasis"><em>Java Connector Architecture</em></span>. This architecture 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. JE supports this architecture.
|
||
</p>
|
||
<p>
|
||
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. Note that the base API is required if you want to do this.
|
||
The JE Resource Adapter supports all three J2EE application server transaction
|
||
types:
|
||
</p>
|
||
<div class="itemizedlist">
|
||
<ul type="disc">
|
||
<li>
|
||
<p>
|
||
No transaction.
|
||
</p>
|
||
</li>
|
||
<li>
|
||
<p>
|
||
Local transactions.
|
||
</p>
|
||
</li>
|
||
<li>
|
||
<p>
|
||
XA transactions.
|
||
</p>
|
||
</li>
|
||
</ul>
|
||
</div>
|
||
<p>
|
||
JCA also includes the Java Transaction API (JTA), which means that JE supports 2 phase commit (XA).
|
||
Therefore, JEs can participate in distributed transactions managed by either a J2EE server or the
|
||
applications direct use of the JTA API.
|
||
</p>
|
||
<p>
|
||
The JE distribution includes an example showing JCA usage in a simple EJB. The Resource Adaptor has been
|
||
tested using JBoss 3.2.6, and the Sun Java System Application Server, version 8.1. Instructions for how to build
|
||
the Resource Adapter and run a simple "smoke test" example for each of the application servers can be found
