Your configuration is flawed and contains duplication, which probably, confuses spring. Both the JtaTransactionManager as well as <tx:jta-transaction-manager /> create a JtaTransactionManager.
Next your <tx:annotation-driven > should point to a JtaTransactionManager but nog it points to a UserTransactionManager.
So first fix your configuration:
<tx:annotation-driven proxy-target-class="true" />
<bean id="atomikosTransactionManager" class="com.atomikos.icatch.jta.UserTransactionManager"
init-method="init" destroy-method="close">
<property name="forceShutdown" value="false" />
</bean>
<bean id="atomikosUserTransaction" class="com.atomikos.icatch.jta.UserTransactionImp">
<property name="transactionTimeout" value="300" />
</bean>
<bean id="transactionManager" class="org.springframework.transaction.jta.JtaTransactionManager">
<property name="transactionManager" ref="atomikosTransactionManager" />
<property name="userTransaction" ref="atomikosUserTransaction" />
<property name="allowCustomIsolationLevels" value="true" />
</bean>
Assuming you are using a recent Spring 3.2 version instead of injecting the dataSource property inject the jtaDataSource on your LocalContainerEntityManagerFactoryBean, next your jpaProperties and jpaPropertiesMap can be cleaned up.
<bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
<property name="jtaDataSource" ref="xaDataSource" />
<property name="packagesToScan" value="com.xxx.model" />
<property name="jpaProperties">
<props>
<prop key="hibernate.hbm2ddl.auto">update</prop>
<prop key="hibernate.transaction.manager_lookup_class">com.atomikos.icatch.jta.hibernate3.TransactionManagerLookup</prop>
</props>
</property>
<property name="jpaVendorAdapter">
<bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter">
<property name="databasePlatform" value="org.hibernate.dialect.MySQL5Dialect" />
<property name="showSql" value="false" />
<property name="generateDdl" value="false" />
</bean>
</property>
</bean>
The hibernate.connection properties are useless as you are injecting a Spring managed datasource. Due to the injection of the jtaDataSource the jpaProperty for javax.persistence.transactionType can be removed. The HibernateJpaVendorAdapter already sets the HibernateJpaDialect and you can use the databasePlatform property to specify the dialect.
Regarding your datasources you should be using the Atomikos wrappers for the datasources so that they are aware of Atomikos. For this use the AtomikosDataSourceBean instead of the xa provided datasource for your JDBC driver.
<bean id="xaDataSource" class="com.atomikos.jdbc.AtomikosDataSourceBean" init-method="init" destroy-method="close">
<property name="xaDataSourceClassName" value="com.mysql.jdbc.jdbc2.optional.MysqlXADataSource" />
<property name="uniqueResourceName" value="xaDataSource"/>
<property name="xaProperties">
<props>
<prop key="url">${mysql_url}</prop>
<prop key="user">root</prop>
<prop key="password">xxx</prop>
</props>
</property>
</bean>
Finally you are using the BasicDataSource as a reference to hibernate whereas you should use the xa enabled (and wrapped) datasource.
