JDBC com JTA no wildlfy

Boa noite,

Supondo que eu tenha um datasource configurado no wildlfy como está abaixo(usando JTA). É necessário commitar as transações e tratar os rollbacks?

<datasource jta="true" jndi-name="java:jboss/datasources/testeDS" pool-name="testeDS" enabled="true" use-java-context="true" use-ccm="true">
                    <connection-url>jdbc:jtds:sybase://172.01.01.105:5000/teste_db</connection-url>
                    <driver>jTDS</driver>
                    <new-connection-sql>SELECT 1</new-connection-sql>
                    <transaction-isolation>TRANSACTION_READ_COMMITTED</transaction-isolation>
                    <pool>
                        <min-pool-size>10</min-pool-size>
                        <max-pool-size>30</max-pool-size>
                        <prefill>true</prefill>
                        <use-strict-min>false</use-strict-min>
                        <flush-strategy>FailingConnectionOnly</flush-strategy>
                    </pool>
                    <security>
                        <user-name>user</user-name>
                        <password>pass</password>
                    </security>
                    <statement>
                        <prepared-statement-cache-size>100</prepared-statement-cache-size>
                        <share-prepared-statements>true</share-prepared-statements>
                    </statement>
                </datasource>
