OSGi Spring Data JPA not working

Question

I want to use Spring Data into my osgi karaf bundle.So i need to register jpa repository as osgi service and use it to another bundle.

It is my configuration,

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:jpa="http://www.springframework.org/schema/data/jpa"
       xmlns:tx="http://www.springframework.org/schema/tx"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:osgi="http://www.springframework.org/schema/osgi"
       xsi:schemaLocation="http://www.springframework.org/schema/beans

        http://www.springframework.org/schema/osgi
        http://www.springframework.org/schema/osgi/spring-osgi-1.2.xsd">


    <context:annotation-config/>


    <bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager">
        <constructor-arg ref="entityManagerFactory"/>
    </bean>

    <osgi:reference id="entityManagerFactory" interface="javax.persistence.EntityManagerFactory"/>

    <tx:annotation-driven/>

    <bean class="org.springframework.orm.jpa.vendor.HibernateJpaDialect"/>

    <jpa:repositories base-package="org.redhat.support.repository"/>

      <osgi:service interface="org.redhat.support.repository.TestingRepository" ref="testingRepository"/>

</beans>

The fuse exception message is,

This error tells you that there is no bundle installed that offers the spring data jpa namespace. Did you install the spring data bundles?

Even if you install everything correctly I am not sure if spring data works in OSGi. Spring has abandoned OSGi a long time ago. So I would try to avoid using any spring technologies in OSGi.

yes, I installed spring data bundles in karaf container. Still the same error appearing. If spring data not supported, then how to achieve spring data method in osgi?...So can we use blueprint openJpa method? – Sridhar Jan 17 '17 at 12:54
