Outjection and Seam interceptors

[gjeudy]

Hi,

I have a case where several Seam components implement the same interface. Another loosely coupled Seam component gets injected likeso.

@Name("foo")
public class Foo implements ICommonInterface {
 
  @In(required=false)
  @Out(required=false)
  private AnotherBijectedField anotherField;

  @Out
  private ICommonInterface commonInterface = this;
}

@Name("bar")
public class Bar implements ICommonInterface {

  @In(required=false)
  @Out(required=false)
  private SomeBijectedField field;

  @Out
  private ICommonInterface commonInterface = this;
}

@Name("looselyCoupledBean")
public class LooselyCoupledBean {

  @In
  private ICommonInterface commonInterface;
}

The problem I see is that injected commonInterface object is not properly initialized (bijected fields are not set) because it seems I have access to the variable outjected in the context which doesn't benefit of any Seam interception goodness.

Is there an alternative in using

@Out private B b = this;

for such a case? Or is that an anti-pattern? I'm considering using some kind of Seam Factory instead:

@Name("factoryManager")
public class CommonInterfaceFactory {

   @In
   private String commonInterfaceBeanName;

   @Factory("commonInterface")
   public ICommonInterface create() {
          return Component.getInstance(commonInterfaceBeanName);
   }
}

Then in Foo and Bar beans I need to outject commonInterfaceBeanName by reading the @Name value attribute... That works by the way.

I'd be interested to hear what others have done to tackle this issue.

Thanks,
