Hi EJB3 Folks,

is the construction of the ejb reference right in the following code?
This is request for review ;)


package org.jboss.wsf.container.jboss50.deployment.metadata;

import java.lang.reflect.Field;
import java.lang.reflect.Method;

import javax.ejb.EJB;

import org.jboss.deployers.structure.spi.DeploymentUnit;
import org.jboss.ejb3.common.resolvers.plugins.FirstMatchEjbReferenceResolver;
import org.jboss.ejb3.common.resolvers.spi.EjbReference;
import org.jboss.ejb3.common.resolvers.spi.EjbReferenceResolver;
import org.jboss.wsf.common.javax.resolvers.AbstractReferenceResolver;

final class EjbBeanReferenceResolver 
extends AbstractReferenceResolver
{
   private final DeploymentUnit unit;
   private final EjbReferenceResolver delegate = new FirstMatchEjbReferenceResolver();
   
   EjbBeanReferenceResolver(final DeploymentUnit unit)
   {
      super(EJB.class);
      this.unit = unit;
   }

   @Override
   protected String resolveField(final Field field)
   {
      EJB ejbAnnotation = field.getAnnotation(EJB.class);
      EjbReference reference = getEjbReference(ejbAnnotation, field.getType());
      return this.delegate.resolveEjb(unit, reference);
   }

   @Override
   protected String resolveMethod(final Method method)
   {
      EJB ejbAnnotation = method.getAnnotation(EJB.class);
      EjbReference reference = getEjbReference(ejbAnnotation, method.getParameterTypes()[0]);
      return this.delegate.resolveEjb(unit, reference);
   }
   
   private EjbReference getEjbReference(EJB ejbAnnotation, Class<?> type)
   {
      String beanInterface = ejbAnnotation.beanInterface().getName();
      if ("".equals(beanInterface))
      {
         beanInterface = type.getName();
      }
      return new EjbReference(ejbAnnotation.beanName(), beanInterface, ejbAnnotation.mappedName());
   }
}
