Clustered datasource migration from JBoss AS 5 to Wildfly 8 - mysql

Question

We plan to migrate from Jboss 5 to Wildfly 8.2. On the database side, we have a three-node Galera cluster with MariaDB 10.
On Jboss 5, we had the following setting in the ds.xml file:
...
<connection-url>jdbc:mysql:loadbalance://ip-node1,ip-node2,ip-node3/DBname</connection-url>
...
Everything worked well on Jboss 5. But I can't achieve the same on Wildfly 8.2. From the management console I was able to add a non-clustered datasource without problems and it works.
Example URL: jdbc:mysql://ip-node1/DBname
But when I try to add the clustered URL as above, I get the following error:
Unexpected HTTP response: 500
Request
{
"address" => [
("subsystem" => "datasources"),
("xa-data-source" => "dsName")
],
"operation" => "test-connection-in-pool"
}
Response
Internal Server Error
{
"outcome" => "failed",
"failure-description" => "JBAS010440: failed to invoke operation: JBAS010447: Connection is not valid",
"rolled-back" => true
}
How could I connect Wildfly to a clustered datasource? I know that it is possible to plug an external load balancer like HAProxy but I would prefer to keep the architecture as simple as possible.

You have to mention the datasource in standalone.xml file inside wildfly-8.2.0.Final_1\standalone\configuration\ as shown below.
<datasource jndi-name="java:/jdbc/DB1" pool-name="PostgresDS" enabled="true" use-java-context="true">
<connection-url>jdbc:postgresql://localhost:5432/DB1</connection-url>
<driver>postgres</driver>
<security>
<user-name>DB1</user-name>
<password>DB1</password>
</security>
</datasource>
<datasource jndi-name="java:/jdbc/DB2" pool-name="PostgresDS1" enabled="true" use-java-context="true">
<connection-url>jdbc:postgresql://localhost:5432/DB2</connection-url>
<driver>postgres</driver>
<security>
<user-name>DB2</user-name>
<password>DB2</password>
</security>
</datasource>
