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"

        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,

How to solve this? Any suggestions. Advance Thanks.

Answer 1

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.
