Access camel blueprint dataSource reference in java - spring

I defined a dataSource in a blueprint.xml which is deployed on karaf:
<bean id="dataSource" class="com.mysql.jdbc.jdbc2.optional.MysqlDataSource">
<property name="url" value="jdbc:mysql://server/db"/>
<property name="user" value="user"/>
<property name="password" value="password"/>
</bean>
<service interface="javax.sql.DataSource" ref="dataSource">
<service-properties>
<entry key="osgi.jndi.service.name" value="jdbc/mysqlDatasource" />
</service-properties>
</service>
In my bundle inside the blueprint.xml I got the following reference and bean for this datasource:
<reference id="dataSource" interface="javax.sql.DataSource"
filter="(osgi.jndi.service.name=jdbc/mysqlDatasource)">
</reference>
<bean id="sql" class="org.apache.camel.component.sql.SqlComponent">
<property name="dataSource" ref="dataSource" />
</bean>
This way I can use the dataSource in my camel sql component.
Is it possible to get this datasource into any other java class inside this bundle?
<bean id="somebean" class="some.path.to.SomeClazz">
<property name="dataSource" ref="dataSource" />
</bean>
Because this obviously doesn't work in this case.

how to configure jms queue inside blueprint.xml

how to configure jms queue(using activemq inside karaf) inside blueprint.xml which present inside karaf deploy folder..
below is my code which shows config for jms connection inside blueprint.xml..
<bean id="activemqConnectionFactory" class="org.apache.activemq.ActiveMQConnectionFactory">
<property name="brokerURL" value="tcp://localhost:61616" />
<property name="userName" value="karaf" />
<property name="password" value="karaf" />
</bean>
<bean id="pooledConnectionFactory" class="org.apache.activemq.pool.PooledConnectionFactory">
<property name="maxConnections" value="8" />
<property name="connectionFactory" ref="activemqConnectionFactory" />
</bean>
<bean id="resourceManager" class="org.apache.activemq.pool.ActiveMQResourceManager" init-method="recoverResource">
<property name="transactionManager" ref="transactionManager" />
<property name="connectionFactory" ref="activemqConnectionFactory" />
<property name="resourceName" value="activemq.localhost" />
</bean>
<reference id="transactionManager" interface="javax.transaction.TransactionManager" />
<service ref="activemqConnectionFactory" interface="javax.jms.ConnectionFactory">
<service-properties>
<entry key="name" value="connectionFactory" />
<entry key="osgi.jndi.service.name" value="jms/connectionFactory" />
</service-properties>
</service>
You don't configure a queue in OSGi, like you did in J2EE. You just use the connection factory in your plain Java or to configure the camel-jms component.

Spring Data Neo4j - Cannot subclass final class class com.sun.proxy.$Proxy76

I have two library projects that are dependencies for my web project. In one of the library projects I am using Spring Data JPA and the other library project I am using Spring Data Neo4j. When I try to start my web project and try to autowire my GraphRepository I get:

JNDI access with Tomcat 7 and embedded HornetQ

I set up a new project with Tomcat 7.0 and an embedded HornetQ JMS server.
I used these 2 tutorials to help me:
http://www.javacodegeeks.com/2010/06/spring-3-hornetq-21-integration.html
http://wash-inside-out.blogspot.com/2010/08/hornetq-jms-integration-with-tomcat.html
But as it is mentioned in the tutos, the Tomcat JNDI repository is readonly (cannot find a way to write) and I configured a "separated" JNDI used by HornetQ, the messaging works, but Tomcat cannot access it.
Normally, in my other projects using Tomcat, I defined the datasource as a global resource in the server.xml and I map it in the context.xml. doing this, the definition of the datasource (jdbc url, credentials, etc...) are outside the application and can be managed by environment (dev, test, prod, ...) but I cannot find a way to do it with the other JNDI.
Currently, the datasource is defined in my application with an external property file for the parameters but I am not really satisfied with this solution.
Here is my Spring configuration:
<!-- enable autowire -->
<context:annotation-config />
<!-- enable transaction demarcation with annotations -->
<tx:annotation-driven transaction-manager="transactionManager" />
<bean id="dataSource" class="org.apache.tomcat.jdbc.pool.DataSource">
<property name="driverClassName" value="com.informix.jdbc.IfxDriver" />
<property name="url" value="${URL}" />
<property name="username" value="${user}" />
<property name="password" value="${password}" />
<property name="maxActive" value="50" />
<property name="maxIdle" value="10" />

How can I managed it in a better way, I mean, define the datasource on the server side as usual? Is there a configuration to tell Tomcat to use the external JNDI I defined or create a read/write repo?

please advise why i get this error, and how to fix it, thanks.
Try using the org.springframework.orm.hibernate4.HibernateTransactionManager
<bean id="transactionManager"
class="org.springframework.orm.hibernate4.HibernateTransactionManager">
<property name="dataSource" ref="dataSource" />
<property name="sessionFactory" ref="sessionFactory" />
</bean>
