ClassCastException thrown on Component.getInstance(GateAction.class, true)

[lokeshpaunikar]

I am new in Seam. I am using Rest services and in one of my rest service I am trying to get Instance by Component like,

GateActionIntf gateAction = (GateActionIntf) Component.getInstance(GateActionImpl.class, true);


So with this I got error java.lang.IllegalStateException: No application context active

then to resolve this I call Lifecycle.beginCall() and Lifecycle.endCall() methods as below,

Lifecycle.beginCall(); 

GateActionIntf gateAction = (GateActionIntf) Component.getInstance(GateActionImpl.class, true); 

Lifecycle.endCall();

Where GateActionIntf is an Interface and GateActionImpl is seam component which implements GateActionIntf. But now I am getting ClassCastException.

Note : In my web service project I don't have any component.xml and seams based configuration, I have just added jboss-seam jar

Is that possible to get instance like that, without any component.xml and seams configuration? Again just highlighting I am getting the Instance but while type casting throws ClassCastException. Any help or comments would be appreciated.

GateActionIntf ==>

public interface GateActionIntf

{

  Response performThisOperation( Operation operation, final DataModel dataModel );

}

GateActionImpl ==>

@Name(value = "getAction")

@AutoCreate

@Scope(ScopeType.STATELESS)

public class GateActionImpl

  implements GateActionIntf

{

  public Response performThisOperation( Operation operation, DataModel dataModel )

  {

    return new Response( operation.getOperationId(), false );

  }

}

you should show here also the sources of GateActionImpl and GateActionIntf. It is certainly related why ClassCastException is thrown.

I have updated the sources of GateActionImpl and GateActionIntf in my question. Please have a look.

Are you sure that you have not missed PUBLIC keyword in interface ?

public interface GateActionIntf

{

  public Response performThisOperation( Operation operation, final DataModel dataModel );

}
