Multiple persistence units are not loading

I was struck , please help on this. My life is happy(Everything is working) when I was using 6 and WebSphere 7.5, but now, we have to migrate to Java 7, WebSphere 8.5.5.12.
My requirement is like, same DB for 3 countries with different schema, all beans are same for 3 countries, but when I am trying to get persistence unit for SG, it is returning default HK one.
<bean class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean" id="MY_HK">

Why to use jpadialect in JpaTransactionManager

I am learning spring 3.0 from Spring in Action.
There it talks about importance of having jpadialect in JpaTranactionManager
<bean id="transactionManager"
class="org.springframework.orm.jpa.JpaTransactionManager">
<property name="entityManagerFactory" ref="entityManagerFactory" />
<property name="jpaDialect" ref="jpaDialect" />
</bean>
<bean id="jpaDialect"
class="org.springframework.orm.jpa.vendor.HibernateJpaDialect" />
However the dialect is already present in declaration of entityManagerFactory via jpaVendorAdaptor.
<bean id="entityManagerFactory" class= "org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
<property name="dataSource" ref="dataSource" />
<property name="jpaVendorAdapter" ref="jpaVendorAdapter" />
</bean>
<bean id="jpaVendorAdapter" class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter">
<property name="database" value="HSQL" />
<property name="showSql" value="true"/>
<property name="generateDdl" value="false"/>
<property name="databasePlatform"
value="org.hibernate.dialect.HSQLDialect" />
</bean>
<bean id="dataSource" class="org.springframework.jdbc.datasource. DriverManagerDataSource">
<property name="driverClassName" value="org.hsqldb.jdbcDriver" />
<property name="url" value="jdbc:hsqldb:hsql://localhost/spitter/spitter" />
<property name="username" value="sa" />
<property name="password" value="" />
</bean>
Is the use of dialect in JpaTranactionManager redundant?

The use of jpaDialect in JpaTransactionManager is no redundant to jpaVendorAdapter config. Their config have different purpose.
You can refer this post with good explanation.

Spring4 with Hibernate4 fails in standalone process

I'm failling to use Spring4 togather with Hibernate4 in a standalone process (no container like tomcat, WAS, ...)
How can I use Hibernate4, Spring4 and Spring data repositories togather in a standalone process?
However I confiugre Spring I allways get the same exception:
Caused by: java.lang.NullPointerException
at org.hibernate.engine.transaction.internal.jta.JtaStatusHelper.getStatus(JtaStatusHelper.java:76)
at org.hibernate.engine.transaction.internal.jta.JtaStatusHelper.isActive(JtaStatusHelper.java:118)
at org.hibernate.engine.transaction.internal.jta.CMTTransaction.join(CMTTransaction.java:149)
When googling for this, I get pointet to some information about hibernate.transaction.jta.platform and the docu for Hibernate 4.3 is here http://docs.jboss.org/hibernate/orm/4.3/devguide/en-US/html_single/#services-JtaPlatform
But the only option I see for my case would be org.hibernate.engine.transaction.jta.platform.internal.NoJtaPlatform but this still leads to the same error.
Here is my Spring config:
<context:component-scan base-package="com.xx.yy" />
<jpa:repositories base-package="com.xx.zz.respositories"></jpa:repositories>
<bean name="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">

I therefore moved from XML to Java config
