的ServiceMix /蓝图/ JPA集成

我已经花了一周试图JPA /集成的ServiceMix 4.5.1 /骆驼JPA 2.10.4 /蓝图在一起。我目前正在使用OpenJPA，但并未与此绑定。 servicemix使用的aries jpa版本是0.3.0。的ServiceMix /蓝图/ JPA集成

堆栈跟踪我不能让过去的是：

我已经尝试了好变化。这是我目前的配置：

的persistence.xml：

<persistence-unit name="customer1" transaction-type="JTA"> 
    <provider>org.apache.openjpa.persistence.PersistenceProviderImpl</provider> 
    <jta-data-source>osgi:service/javax.sql.DataSource/(osgi.jndi.service.name=jdbc/prototypedb)</jta-data-source> 
    <class>...</class> 
</persistence-unit>

骆驼的context.xml

<service id="PrototypeDB" interface="javax.sql.DataSource"> 
    <service-properties> 
     <entry key="osgi.jndi.service.name" value="jdbc/prototypedb"/> 
    </service-properties> 
    <bean class="org.apache.commons.dbcp.BasicDataSource"> 
     <property name="driverClassName"  value="com.mysql.jdbc.Driver"/> 
     <property name="url"     value="jdbc:mysql://localhost:3306/prototype"/> 
     <property name="username"    value="root"/> 
     <property name="password"    value="..."/> 
    </bean> 
</service> 

<service ref="workoutEntity" interface="..."/> 
<bean id="workoutEntity" class="..."> 
    <jpa:unit index="0"   unitname="customer1" /> 
    <tx:transaction method="*" value="Required"/> 
</bean>

实体Bean（用常规）

@Entity 
@Table(name='customer1') 
@Slf4j 
class WorkoutEntity implements IWorkoutEntity{ 

    private EntityManager entityManager 

    WorkoutEntity(final EntityManagerFactory entityManagerFactory) { 
     this.entityManager = entityManagerFactory.createEntityManager() 
    } 

    @Handler 
    void create(@Body final String input) { 
     // ... 
    } 
}

我已经尝试了多个不同的DataSource实现，包括BasicDataSource，org.springframework.jdbc.datasou rce.SimpleDriverDataSource和com.mysql.jdbc.jdbc2.optional.MysqlDataSource。全部导致IllegalArgumentException。

我也尝试使用JNDI放弃，而是直接在persistence.xml定义数据源。这会导致OpenJPA包中的ClassNotFoundException，因为它不会导入mysql驱动程序。我更喜欢在我的camel-context.xml中定义这个，并且不希望重新绑定OpenJPA jar。

您可能还需要安装aries JNDI功能。这有助于通过JNDI查找调用OSGi服务。这应该是缺失的一块。
