FileNotFoundException..Classpath resource not found in spring OSGI jar - spring

Question

I have created one sample osgi plugin and deploy it in WSO2-ESB container.
Now I want to user Spring in osgi bundle for bean management.So I have created one spring-beans.xml file as shown below.
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.2.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-3.2.xsd">
<!-- Add DAO Impl bean entry here and Add bean reference as required -->
<bean id="xyzDAO" class="x.y.z.ABCImpl">
</bean>
<!-- Add Service Impl bean entry here and attach DAO reference -->
<bean id="abcService" class="x.y.z.ABCServiceImpl">
<property name="xyzDAO" ref="xyzDAO"/>
</bean>
Then I have created one Class and use ClassPathXmlApplicationContext for loading xml file as shown below
ApplicationContext appContext = new ClassPathXmlApplicationContext("spring-beans.xml");
I have called this class from BundleActivator which runs on bundle startup.
When i deploy this plugin into [WSO2-HOME]/repository/components/dropins/ i got the following exception.
org.springframework.beans.factory.BeanDefinitionStoreException: IOException parsing XML document from class path resource [spring-beans.xml]; nested exception is java.io.FileNotFoundException: class path resource [spring-beans.xml] cannot be opened because it does not exist

When i run this plugin from eclipse it runs smoothly.
I can't figure out the problem why it's so happened.If you have any suggestion or solution then please let me know so I can resolve it.
Thanks in advance.

Instead of deploy into [WSO2-HOME]/repository/components/dropins,
deploy in [WSO2-HOME]/repository/components/lib.
Must restart the server and check once again.
And also check this.

You need to address the classpath issues that you have with Spring. See the answer for this related question.
