I am trying to create a chain of deployers which would allow me to do something like the
following:
- DeployerA in POST_CLASSLOADER phase would attach some metadata XYZ to a unit and *also*
attach the same XYZ as a BeanMetaData to the unit, so that some of the fields marked with
@Inject get processed appropriately.
- DeployerB in REAL phase adds XYZ as an input and expects a completely processed XYZ
(i.e. the @Inject within XYZ to have been completed) when the deploy method is called.
The pseudo-code:
public class DeployerA extends AbstractDeployer
{
public DeployerA()
{
// Set the Stage to post-CL
this.setStage(DeploymentStages.POST_CLASSLOADER);
this.setInput(blah.class);
      // we output
XYZ     
this.addOutput(XYZ.class);
// we also output XYZ as BMD
this.addOutput(BeanMetaData.class);
}
/**
* @see
org.jboss.deployers.spi.deployer.Deployer#deploy(org.jboss.deployers.structure.spi.DeploymentUnit)
*/
@Override
public void deploy(DeploymentUnit unit) throws DeploymentException
{
XYZ output = new XYZ();
// add as a attachment
unit.addAttachment(XYZ.class, output);
BeanMetaDataBuilder builder = BeanMetaDataBuilder.createBuilder("blahbmd",
output.getClass().getName());
builder.setConstructorValue(output);
// attach XYZ as a BMD
unit.addAttachment(BeanMetaData.class + ":" + "blahbmd",
builder.getBeanMetaData());
}
}
public class DeployerB extends AbstractSimpleRealDeployer
{
public DeployerB()
{
// input
super(XYZ.class);
}
@Override
public void deploy(DeploymentUnit unit, XYZ mcProcessedXYZ) throws DeploymentException
{
          //
here we expect a XYZ which has been processed for @Inject points by MC
          Object
injectedField = mcProcessedXYZ.getInjectedField();
}
}
So the DeployerB is expecting an input which is already processed as a BMD. However, from
what i see, the DeployerB gets called before any of the processing happens on XYZ. So,
although the unit has XYZ has an attachment, when it gets processed in DeployerB, it's
not injected with any injectable fields. I can see that the injection into XYZ takes place
after this DeployerB is done with the processing.
I am sure that i am not doing it right. So is there a way wherein i can achieve what i am
trying to do?
P.S: incallback for XYZ is not an option because i need "deployer" semantics in
this usecase.
