java - Spring : 2 EntityManagerFactory in 1 transaction -

i'd access 2 databases in same application. each database connection, have entitymanagerfactory.
problem : can't merge 2 entity in 2 databases in same transaction.

there beans.xml file :

    <context:component-scan base-package="com.example.testdatabase.business" />     <context:component-scan base-package="com.example.testdatabase.service" />     <context:component-scan base-package="com.example.testdatabase.ui" />      <bean id="entitymanagerfactoryorder"         class="org.springframework.orm.jpa.localcontainerentitymanagerfactorybean">         <property name="datasource" ref="datasourceorder" />         <property name="packagestoscan" value="com.example.testdatabase.business.order" />         <property name="jpavendoradapter">             <bean class="org.springframework.orm.jpa.vendor.hibernatejpavendoradapter" />         </property>         <property name="jpaproperties">             <props>                 <prop key="hibernate.hbm2ddl.auto">validate</prop>                 <prop key="hibernate.dialect">org.hibernate.dialect.postgresqldialect</prop>                 <prop key="hibernate.show_sql">true</prop>                 <prop key="validationquery">select 1 dual</prop>                 <prop key="testonborrow">true</prop>             </props>         </property>         <property name="persistenceunitname" value="orderpu" />     </bean>      <bean id="datasourceorder" class="org.springframework.jndi.jndiobjectfactorybean">         <property name="jndiname" value="java:jboss/datasources/ordercita" />     </bean>      <bean id="transactionmanagerorder" class="org.springframework.orm.jpa.jpatransactionmanager">         <property name="entitymanagerfactory" ref="entitymanagerfactoryorder" />         <property name="jpadialect">             <bean class="org.springframework.orm.jpa.vendor.hibernatejpadialect" />         </property>     </bean>      <bean id="entitymanagerfactoryperson"         class="org.springframework.orm.jpa.localcontainerentitymanagerfactorybean">         <property name="datasource" ref="datasourceperson" />         <property name="packagestoscan" value="com.example.testdatabase.business.person" />         <property name="jpavendoradapter">             <bean class="org.springframework.orm.jpa.vendor.hibernatejpavendoradapter" />         </property>         <property name="jpaproperties">             <props>                 <prop key="hibernate.hbm2ddl.auto">create</prop>                 <prop key="hibernate.dialect">org.hibernate.dialect.postgresqldialect</prop>                 <prop key="hibernate.show_sql">true</prop>             </props>         </property>         <property name="persistenceunitname" value="personpu" />     </bean>      <bean id="datasourceperson" class="org.springframework.jndi.jndiobjectfactorybean">         <property name="jndiname" value="java:jboss/datasources/person" />     </bean>      <bean id="transactionmanagerperson" class="org.springframework.orm.jpa.jpatransactionmanager">         <property name="entitymanagerfactory" ref="entitymanagerfactoryperson" />         <property name="jpadialect">             <bean class="org.springframework.orm.jpa.vendor.hibernatejpadialect" />         </property>     </bean>      <tx:annotation-driven/> 

my repository :

@repository public class repo {     @persistencecontext(unitname="orderpu")    @qualifier(value="entitymanagerfactoryorder")    protected entitymanager emorder;     @persistencecontext(unitname="personpu")    @qualifier(value="entitymanagerfactoryperson")    protected entitymanager emperson;     public void save() {        order o = new order();        o.setthestring("the order");         emorder.merge(o);        emorder.close();         person p = new person();        p.setthestring("the person");         emperson.merge(p);        emperson.close();     } } 

my service :

@service public class manager {    @autowired    private repo repo;     @transactional(value="transactionmanagerorder")    public void save1() {        repo.save();    }     @transactional(value="transactionmanagerperson")    public void save2() {        repo.save();    }     @transactional    public void save3() {        repo.save();    } } 

method "save1()" merge order.
method "save2()" merge person.
merge order , person same transaction.

thanks help

ps : i'm sorry english...

* edit *
tried bitronix have nullpointerexception.
added line in jpaproperties :
org.hibernate.engine.transaction.jta.p‌​latform.internal.bitronixjtaplatform

here new beans.xml file :

in manager class, removed @transactional annotation.
in repo class, removed @qualifier annotation.

you using local transaction managers manage transactions against 1 data store @ time. managing transactions span across multiple data stores, need jta compliant transaction manager.

see this sample app example of using bitronix jta transaction manager 2 entitymanagers.
