[jboss-user] [Microcontainer] - Re: ClassLoaderMetaData not propagating (yet?) to classloade

[gcompienne]

Ok, here is the code for TestDescribeDeployer:


  | package protomcf.test.deployer;
  | 
  | import java.util.List;
  | 
  | import org.jboss.deployers.spi.DeploymentException;
  | import org.jboss.deployers.spi.deployer.DeploymentStages;
  | import org.jboss.deployers.spi.deployer.helpers.AbstractRealDeployer;
  | import org.jboss.deployers.structure.spi.ClassLoaderFactory;
  | import org.jboss.deployers.structure.spi.DeploymentUnit;
  | import org.jboss.deployers.structure.spi.classloading.ClassLoaderMetaData;
  | import org.jboss.logging.Logger;
  | 
  | import protomcf.test.metadata.ParserMetaData;
  | 
  | public class TestDescribeDeployer extends AbstractRealDeployer {
  | 
  |    private final Logger log = Logger.getLogger(TestDescribeDeployer.class); 
  |    
  |    public TestDescribeDeployer() {
  |       setStage(DeploymentStages.DESCRIBE);
  |       setInputs(new Class<?>[] {ParserMetaData.class, ClassLoaderMetaData.class});
  |       //setInput(ParserMetaData.class);
  |       //setInput(ClassLoaderMetaData.class);
  |       setOutput(ClassLoaderMetaData.class);
  |       //setOutput(TestMetaData.class);
  |       //setAllInputs(true);  
  |    }
  |    
  |    @Override
  |    protected void internalDeploy(DeploymentUnit unit) throws DeploymentException {
  |       log.debug("TestDescribeDeployer deploy called...");
  |       ClassLoaderMetaData clmd = unit.getAttachment(
  |             ClassLoaderMetaData.class); 
  |       if (clmd != null) {
  |          Utils.displayCLMetaData(clmd, log);
  |       }
  |       ClassLoaderFactory clf = unit.getAttachment(ClassLoaderFactory.class);
  |       if (clf != null) {
  |          log.debug("ClassLoaderFactory is " + clf);
  |       } else {
  |          log.debug("ClassLoaderFactory not present...");
  |       }      
  |       ParserMetaData pmd = unit.getAttachment(ParserMetaData.class);
  |       if (pmd != null) {
  |          log.debug("ParserMetaData found: " + pmd);
  |          clmd.setDomain("TestAppDomain");
  |          clmd.setImportAll(false);
  |          Utils.displayCLMetaData(clmd, log);
  |          unit.addAttachment(ClassLoaderMetaData.class, clmd);
  |       } else {
  |          log.debug("ParserMetaData not present...");
  |       }     
  |    }
  | 
  | }
  | 

Also here follows a more readable version of the log:

On the log, you can see that TestDescribeDeployer did set the domain to "TestAppDomain" and the TestClassloaderDeployer clearly pick that up.

However on the two lines where the base class loader is created (in between the describe and CL deployer) we can clearly see that the domain is equal to default. I wonder what would also be the status of the "import" state but I can't display it yet (I will need to give it a go with a debugger at some point).

Thanks for your help.

Gilles.
