With JOTM, the same object implements both the + * {@link javax.transaction.UserTransaction} and the + * {@link javax.transaction.TransactionManager} interface, + * as returned by this FactoryBean. + *
+ *A local JOTM instance is well-suited for working in conjunction with + * ObjectWeb's XAPool, e.g. with bean + * definitions like the following: + *
+ *+ * <bean id="jotm" class="org.springframework.transaction.jta.JotmFactoryBean"/> + * + * <bean id="transactionManager" class="org.springframework.transaction.jta.JtaTransactionManager"> + * <property name="userTransaction" ref="jotm"/> + * </bean> + * + * <bean id="innerDataSource" class="org.enhydra.jdbc.standard.StandardXADataSource" destroy-method="shutdown"> + * <property name="transactionManager" ref="jotm"/> + * <property name="driverName" value="..."/> + * <property name="url" value="..."/> + * <property name="user" value="..."/> + * <property name="password" value="..."/> + * </bean> + * + * <bean id="dataSource" class="org.enhydra.jdbc.pool.StandardXAPoolDataSource" destroy-method="shutdown"> + * <property name="dataSource" ref="innerDataSource"/> + * <property name="user" value="..."/> + * <property name="password" value="..."/> + * <property name="maxSize" value="..."/> + * </bean>+ * + * Note that Spring's {@link org.springframework.transaction.jta.JtaTransactionManager} will automatically detect + * that the passed-in UserTransaction reference also implements the + * TransactionManager interface. Hence, it is not necessary to specify a + * separate reference for JtaTransactionManager's "transactionManager" property. + * + *
Implementation note: This FactoryBean uses JOTM's static access method + * to obtain the JOTM {@link org.objectweb.jotm.Current} object, which + * implements both the UserTransaction and the TransactionManager interface, + * as mentioned above. + * + * @author Juergen Hoeller + * @see org.springframework.transaction.jta.JtaTransactionManager#setUserTransaction + * @see org.springframework.transaction.jta.JtaTransactionManager#setTransactionManager + * @see org.objectweb.jotm.Current + * @since 21.01.2004 + */ +public class JotmFactoryBean implements FactoryBean, DisposableBean, InitializingBean { + + private Current jotmCurrent; + + private Jotm jotm; + private String jotmHome; + private Integer defaultTimeout; + private Boolean transactionRecovery; + + + /** + * Set the default transaction timeout for the JOTM instance. + *
