> I have a sender bean and a receiver bean, both configured using 
> <bean:endpoint ... bean="#...".  The problem is that the PreDestroy method is 
> being called after every MessageExchange is finished.
> According to the documentation:
> Attention: The Bean Endpoint schema allows to set a Bean or a Bean Name. The 
> Bean will create a single instance of the POJO per endpoint whereas the Bean 
> Name will create an instance per request (message exchange).
> I have in my xbean.xml:
> <?xml version="1.0" encoding="UTF-8"?>
> <beans xmlns:bean="http://servicemix.apache.org/bean/1.0";
>        xmlns:example="http://servicemix.apache.org/example";>
>   <bean:endpoint service="example:sender" endpoint="senderEndpoint" 
> bean="#sender"/>
>   <bean:endpoint service="example:receiver" endpoint="receiverEndpoint" 
> bean="#receiver"/>
>   <bean id="sender" class="example.Sender">
>     <property name="target" value="example:receiver"/>
>   </bean>
>   
>   <bean id="receiver" class="example.Receiver">
>   </bean>
> </beans>
> The receiver simply implements MessageExchangeListener.
> The PostConstruct and PreDestroy only gets called once on the sender
> The PostConstruct only gets called once on the receiver
> However, the PreDestroy gets called on the receiver for each request.
> I noticed in BeanEndpoint, there is the following method:
> protected void checkEndOfRequest(Request request, Object corId) {
>         if (request.getExchange().getStatus() != ExchangeStatus.ACTIVE) {
>             ReflectionUtils.callLifecycleMethod(request.getBean(), 
> PreDestroy.class);
>             //request.setBean(null);
>             //request.setExchange(null);
>             requests.remove(corId);
>         }
>     }
> It doesn't look like this class pays any attention to whether the bean is 
> supposed to be a single instance of an instance-per-request, which is 
> probably the cause of the problem.
> If you need me to attach an example, please let me know.
