Multiple components -------------------- Key: JBMICROCONT-159 URL: http://jira.jboss.com/jira/browse/JBMICROCONT-159 Project: JBoss MicroContainer Issue Type: Bug Components: Deployment Affects Versions: JBossMC_2_0_0 Beta3 Reporter: Scott M Stark There is a problem with how component deployments are handled. When a DeploymentUnit contains multiple sources of component metadata (a jar with a META-INF/*-beans.xml,*-service.xml for example), duplicate processing of components is occuring. This is due to the AbstractComponentDeployer.deployComponents query for the component metadata: protected void deployComponents(DeploymentUnit unit) throws DeploymentException { if (compVisitor == null) return; Set<? extends C> components = unit.getAllMetaData(componentType); for (C component : components) compVisitor.deploy(unit, component); } The DeploymentUnit.getAllMetaData(componentType) for the current DeploymentComponentContext looks to its parent for metadata. This combined with the recursive processing in the MainDeployerImpl.commitDeploy: private void commitDeploy(Deployer deployer, DeploymentContext context, Set<DeploymentContext> components) throws DeploymentException { DeploymentContext[] theComponents = null; if (components != null && components.isEmpty() == false) theComponents = components.toArray(new DeploymentContext[components.size()]); DeploymentUnit unit = context.getDeploymentUnit(); deployer.commitDeploy(unit); try { if (theComponents != null) { for (int i = 0; i < theComponents.length; ++i) { try { Set<DeploymentContext> componentComponents = theComponents[i].getComponents(); commitDeploy(deployer, theComponents[i], componentComponents); } catch (DeploymentException e) { // Unwind the previous components for (int j = i-1; j >=0; --j) prepareUndeploy(deployer, theComponents[j], true); throw e; } } } } catch (DeploymentException e) { prepareUndeploy(deployer, context, false); throw e; } } Results in a structure like: DU(some.jar) + CDC(Bean1) + CDC(ServiceBean2) + CDC(Bean2) + CDC(ServiceBean2) + CDC(ServiceBean1) + CDC(ServiceBean2) + CDC(ServiceBean2) The service deployer components are being recursively added to the kernel components and duplicate install errors result.
