JBoss Microkernel Deployment

The deployer is a production line of aspects.

Methods

• Deploy - deploy a url

• Undeploy - undeploy a url

• Redeploy - redeploy a url

Aspects

Example aspects:

• Class enhancement - defines any bytecode manipulation mechanism

• Classloading - defines where resources and classes can be loaded

• Bean metadata - determines the metadata for the POJOs.

• Bean deployer - instantiates POJOs/services similar to -service.xml

• Profile deployer - deploys profile information, e.g. which services should be started

• Logging - deploys logging configuration

• Security - deploys JAAS configuration

Virtual File System (VFS)

The virtual file system will allow the deployment to deal with a deployment in a transparent manner.

• Handles protocol specific behaviour

• file:/

  versus

  http:/

  etc.

• Consistent view of the deployment

• Handles special behaviour, e.g. war and ear deployments

• Allows overrides of deployment locations, e.g. alt-dd or deployment from an IDE
