java - Why are JPA changes using an EntityManager not committed in a Spring Service when JtaTransactionManager is used? -

i need use org.springframework.transaction.jta.jtatransactionmanager transactionmanager in spring service. however, not commit change in jpa entities. know if use jpatransactionmanager works. but, need jtatransactionmanager. so, please don't recommend use jpatransactionmanager. spring service class is:

package testspring.view;  import javax.persistence.entitymanager; import javax.persistence.persistencecontext;  import org.springframework.stereotype.service; import org.springframework.transaction.annotation.transactional;  import testspring.model.regions;   @service public class hellobs {     @persistencecontext     private entitymanager entitymanager;      public hellobs() {         super();     }      @transactional()     public void dosomething() {         regions region = new regions();         region.setregionname("antarctica");         entitymanager.persist(region);     } } 

and spring xml config is:

<?xml version="1.0" encoding="utf-8" standalone="no"?> <beans xmlns="http://www.springframework.org/schema/beans"        xmlns:context="http://www.springframework.org/schema/context"        xmlns:tx="http://www.springframework.org/schema/tx"        xmlns:xsi="http://www.w3.org/2001/xmlschema-instance"        xmlns:mvc="http://www.springframework.org/schema/mvc"        xmlns:jee="http://www.springframework.org/schema/jee"        xsi:schemalocation="                http://www.springframework.org/schema/beans                http://www.springframework.org/schema/beans/spring-beans-3.2.xsd                http://www.springframework.org/schema/tx                http://www.springframework.org/schema/tx/spring-tx-3.2.xsd                http://www.springframework.org/schema/context                http://www.springframework.org/schema/context/spring-context-3.2.xsd                http://www.springframework.org/schema/mvc                http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd                http://www.springframework.org/schema/jee                 http://www.springframework.org/schema/jee/spring-jee-3.2.xsd">     <context:component-scan base-package="testspring.view"/>     <context:annotation-config/>     <mvc:annotation-driven/>     <bean class="org.springframework.web.servlet.view.internalresourceviewresolver">         <property name="viewclass"                   value="org.springframework.web.servlet.view.jstlview"/>         <property name="prefix" value="/web-inf/jsp/"/>         <property name="suffix" value=".jsp"/>     </bean>     <mvc:default-servlet-handler/>     <bean id="datasource" name="datasource"           class="org.springframework.jndi.jndiobjectfactorybean">         <property name="jndiname" value="jdbc/hrds"/>         <property name="resourceref" value="true"/>     </bean>     <bean class="org.springframework.orm.jpa.support.persistenceannotationbeanpostprocessor"/>     <bean id="entitymanagerfactory"           class="org.springframework.orm.jpa.localcontainerentitymanagerfactorybean">         <property name="datasource" ref="datasource"/>         <property name="packagestoscan" value="testspring.model"/>         <property name="jpavendoradapter">             <bean class="org.springframework.orm.jpa.vendor.hibernatejpavendoradapter"/>         </property>         <property name="jpaproperties">             <props>                 <prop key="hibernate.dialect">org.hibernate.dialect.oracle10gdialect</prop>                 <prop key="javax.persistence.validation.mode">auto</prop>                 <prop key="hibernate.archive.autodetection">class</prop>                 <prop key="hibernate.ejb.naming_strategy">org.hibernate.cfg.improvednamingstrategy</prop>                 <prop key="hibernate.connection.charset">utf-8</prop>                 <prop key="hibernate.connection.useunicode">true</prop>                 <prop key="hibernate.connection.characterencoding">utf-8</prop>                 <prop key="hibernate.show_sql">true</prop>                 <prop key="hibernate.format_sql">true</prop>                 <prop key="hibernate.transaction.flush_before_completion">true</prop>                 <prop key="hibernate.transaction.auto_close_session">true</prop>                 <prop key="hibernate.connection.release_mode">auto</prop>             </props>         </property>     </bean>     <bean id="transactionmanager"           class="org.springframework.transaction.jta.jtatransactionmanager"></bean>     <tx:annotation-driven transaction-manager="transactionmanager"/> </beans> 

how can have changes in jpa entities committed using jtatransactionmanager?

thanks @bond - java bond solution following steps:

• set jtadatasource instead of datasource.
• use <tx:jta-transaction-manager/> instead of <tx:annotation-driven transaction-manager="transactionmanager"/>.
• add <prop key="hibernate.transaction.jta.platform">org.hibernate.service.jta.platform.internal.weblogicjtaplatform</prop>. there different classes in org.hibernate.service.jta.platform.internal package can used different application servers.

so final spring xml config is:
