> The problem wasn't the lack of a loader to load <componentType> elems.....rather, it was this line in JavaComponentTypeLoader:
> protected PojoComponentType loadFromSidefile(URL url, DeploymentContext deploymentContext) throws LoaderException {
> return loaderRegistry.load(null, url, PojoComponentType.class, deploymentContext);
> }
> Thie use of 'PojoComponentType.class' as argument is a problem. In LoaderRegistryImpl.load, we do (line 109):
> ModelObject mo = load(parent, reader, ctx);
> if (type.isInstance(mo)) {
> So we're loading into a ModelObject, (more specifically, org.apache.tuscany.spi.model.ComponentType), but the 'type' here is :
> PojoComponentType.class
> which is in pkg org.apache.tuscany.core.implementation.java and passed into the load(..) call.
> On the dev list, Raymond Feng answered my email describing the problem with this:
> The ComponentTypeElementLoader creates a generic ComponentType from
> the XML file but the code expects an instance of PojoComponentType. Now the
> question is how to map the generic ComponentType into the PojoComponentType
> if it's required. Jim, do you have ideas?
> Jim Marino replied:
> We should probably have the implementation loader handle creation of
> the particular component type class and populate it by recursing back
> into the loader since it is minimal code
> (ComponentTypeElementLoader). This would be a nice patch for someone
> to work on :-)
