[weld-dev] Portable extension for injecting Seam beans

Folks, would someone please try out the following portable extension for me. It should be enough to let you typesafe-inject a Seam2 component using Weld, e.g. @Inject @Qualifier MySeamComponent msc; It's not enough to allow the use of typesafe injection in the seam component itself, however. Please test this for me, thanks! ++++ package org.seamframework; import java.util.Collections; import java.util.Set; import javax.enterprise.context.RequestScoped; import javax.enterprise.context.spi.CreationalContext; import javax.enterprise.event.Observes; import javax.enterprise.inject.spi.AnnotatedType; import javax.enterprise.inject.spi.BeforeBeanDiscovery; import javax.enterprise.inject.spi.Extension; import javax.enterprise.inject.spi.InjectionPoint; import javax.enterprise.inject.spi.InjectionTarget; import javax.enterprise.inject.spi.ProcessInjectionTarget; import javax.enterprise.util.AnnotationLiteral; import org.jboss.seam.Component; import org.jboss.seam.annotations.Name; public class SeamComponentExtension implements Extension { void beforeBeanDiscovery(@Observes BeforeBeanDiscovery bbd) { bbd.addStereotype(Name.class, new AnnotationLiteral<RequestScoped>() {}); //TODO: put it in a @StatelessScope! } <X> void processInjectionTarget(@Observes final ProcessInjectionTarget<X> pit) { final AnnotatedType<X> at = pit.getAnnotatedType(); if ( at.isAnnotationPresent(Name.class) ) { if ( !pit.getInjectionTarget().getInjectionPoints().isEmpty() ) { throw new RuntimeException("CDI injection points not supported for Seam2 components"); } InjectionTarget<X> it = new InjectionTarget<X>() { @Override public void inject(X instance, CreationalContext<X> ctx) { //TODO figure out a way to inject into the Seam component } @Override public void postConstruct(X instance) {} @Override public void preDestroy(X instance) {} @Override public void dispose(X instance) {} @Override public Set<InjectionPoint> getInjectionPoints() { return Collections.EMPTY_SET; } @Override public X produce(CreationalContext<X> ctx) { //TODO: it would be better to override Component.instantiateJavaBean() to call // it.produce(), in order to get injection, etc, but then we would have // to figure out a way to replace the Seam Component object return (X) Component.getInstance( at.getJavaClass(), true ); } }; pit.setInjectionTarget(it); } } } -- Gavin King gavin.king(a)gmail.com http://in.relation.to/Bloggers/Gavin http://hibernate.org http://seamframework.org
