Got NPE when invoking POJO producer

[xiaotao183]

Hi, 

I was trying to use the @producer annotation in serivcemix to send a message
to an endpoint. 

Here is the code 

@WebService(endpointInterface =
"org.apache.servicemix.examples.cxf.HelloWorld") 
public class HelloWorldImpl implements HelloWorld 
{ 
    @EndpointInject(uri="direct:start") 
    protected ProducerTemplate template; 

    public String sayHi(String text) 
    { 
        produce(); 
        return "Hello " + text; 
    } 

    public void produce() 
    { 
        template.sendBody("hello world"); 
    } 
} 

and this is the beans.xml

I got NPE when invoking the producertemplate to send message at the this
line 'template.sendBody("hello world");' 

Looks like the producertemplate was not injected to the bean correctly. 

Thanks
