Hi all,
I am trying to implement custom namespace handler which uses couple of
pre-defined beans (blueprintContainer, blueprintBundle). I have big troubles
because bundles which uses my namespace must explicity declare dependencies on
org.osgi.service.blueprint.container and org.osgi.framework packages. This
stays in deep conflict with my understanding of custom namespace handlers
because I wanted to hide implementation details and all dependencies of
implementation behind handler.
My XSD is following:
<import namespace="http://www.osgi.org/xmlns/blueprint/v1.0.0";
schemaLocation="http://www.osgi.org/xmlns/blueprint/v1.0.0/blueprint.xsd"/>
<element name="resource-injector">
<complexType>
<complexContent>
<extension base="beans:Tcomponent" />
</complexContent>
</complexType>
</element>
The consumer bundles should use element <nsprefix:resource-injector
id="blueprintResourceInjector" /> to obtain instance of
org.axonframework.saga.ResourceInjector (this is SPI interface from
axonframework).
Element parser is very simple:
@Override
public Metadata parse(Element element, ParserContext context) {
MutableBeanMetadata metadata = createObjectOfClass(context,
BlueprintResourceInjector.class.getName());
metadata.setId(getId(element, context));
metadata.addArgument(createRef(context, "blueprintBundle"),
Bundle.class.getName(), 0);
metadata.addArgument(createRef(context, "blueprintContainer"),
BlueprintContainer.class.getName(), 1);
return metadata;
}
And result is unexpected:
Unable to start blueprint container for bundle com.axon.examples.simple-bus
org.osgi.service.blueprint.container.ComponentDefinitionException: Unable to
load class org.osgi.framework.Bundle from recipe
BeanRecipe[name='blueprintResourceInjector']
