Deployment on JBoss AS 7 or JBoss EAP 6 is a fairly straightforward process, steps of which are shown below. The only non-trivial step is the creation of a new JBoss module with Hazelcast libraries.
<jboss_home>/modules/system/layers/base/com/hazelcast/main
.hazelcast-
<version>.jar
and hazelcast-jca-
<version>.jar
into the directory you created in the previous step.Create the file module.xml
and place it to the same directory. This file should have the below content.
<module xmlns="urn:jboss:module:1.0" name="com.hazelcast">
<resources>
<resource-root path="."/>
<resource-root path="hazelcast-<version>.jar"/>
<resource-root path="hazelcast-jca-<version>.jar"/>
</resources>
<dependencies>
<module name="javax.api"/>
<module name="javax.resource.api"/>
<module name="javax.validation.api"/>
<module name="org.jboss.ironjacamar.api"/>
</dependencies>
</module>
At this point, you have a new JBoss module with Hazelcast in it. You can now start JBoss and deploy the hazelcast-jca-rar-
<version>.rar
file via JBoss CLI or Administration Console.
Once the Hazelcast Resource Adapter is deployed, you can start using it. The easiest way is to let a container inject ConnectionFactory
into your beans.

try {
return (HazelcastConnection) connectionFactory.getConnection();
} catch (ResourceException e) {
throw new RuntimeException("Error while getting Hazelcast connection", e);
}
}
private void closeConnection(HazelcastConnection hzConn) {
if (hzConn != null) {
try {
hzConn.close();
} catch (ResourceException e) {
log.log(Level.WARNING, "Error while closing Hazelcast connection.", e);
}
}
}
