Ron Gavlin commented on SM-1305:
--------------------------------
I have a SMX-Bean Pojo that requires a StoreFactory & Store. When the Pojo is
initialized, I would like to include code similar to that listed below:
if (store == null) {
if (storeFactory == null) {
storeFactory = new MemoryStoreFactory();
}
store = storeFactory.open(getServiceEndpoint().getKey());
}
For this use case, it would be convenient if a ServiceEndpoint could be
dependency-injected into my Pojo using @Resource in the same way the
ComponentContext & DeliveryChannel are dependency-injected. This would require
a few line change to org.apache.servicemix.bean.BeanEndpoint.injectBean(final
Object target).
Also, are there other general SMX-Bean use cases where a StoreFactory and Store
might be needed? If so, would it make sense to expose these in the SMX-Bean
schema?
Let me know..

> Key: SM-1305
> URL: https://issues.apache.org/activemq/browse/SM-1305
> Project: ServiceMix
> Issue Type: New Feature
> Components: servicemix-bean
> Affects Versions: 3.2.1
> Reporter: Ron Gavlin
>
> The deprecated, LightWeight container provided a convenient base class,
> TransformComponentSupport, that made it easy for non-JBI experts to write
> simple transforms in Java. In order to accomplish the same task with
> servicemix-bean, a developer must have have in-depth, JBI knowledge. A helper
> class or base class should be created to make it easier for developers to
> write transforms using servicemix-bean. A base class would also be useful to
> ease the implementation of non-Transform servicemix-beans.
> I suggest the following class names for the proposed two base classes:
> 1. org.apache.servicemix.bean.support.BeanSupport.java - this class provides
> servicemix-bean specific functionality currently offered by the combination
> of "org.apache.servicemix.components.util.PojoSupport.java" and
> "org.apache.servicemix.components.util.ComponentSupport.java"
> 2. org.apache.servicemix.bean.support.TransformBeanSupport.java - this class
> extends "org.apache.servicemix.bean.support.BeanSupport.java" (above),
> implements MessageExchangeListener, and provides servicemix-bean specific
> functionality currently offered by
> "org.apache.servicemix.components.util.TransformComponentSupport.java"
