JBoss Microcontainer High Level Road Map

Discussion

This is not a replacement for JIRA. It is intended to give an overview of what

needs doing (across multiple projects) for JBoss5 to complete the first stages of the Microcontainer integration. Some of this isn't necessarily "first stage".

This initial draft is a "brain dump" - it isn't complete.

I will link comments sections to discussion threads and JIRA tasks as I have the time, we discuss them

and I create the more detailed information

AOP/MC integration

• Proxy - Simple proxy similar to org.jboss.proxy (don't expose the plumbing)

• ClassAdapter - Class/Instance integration between the MC and AOP for cross cutting dependencies (still needs agreement)

• Decorators - "Introductions" based on contextual metadata and MC lifecycle

AOP Metadata

• Annotations - Integration between MC annotation overrides and AOP annotation processing

• Metadata - contextual deployment (integration with domains for applications/subsystems) with runtime overrides and transport from the client

• Typesafe metadata

• Javassist instead of reflection for ClassInfo

AOP Deployment

• MC Beans - IOC style deployment of AOP metadata

• Simplified XML - Use case and simplified xml to hide the complexity for common cases

ClassLoading

• VFS ClassLoader/Domain - linked with context

Microcontainer configuration

• Tidyup the configurator and fix/test the classloading properly

• Make the BeanInfo available to others, e.g. xml parser

• Make the errors more human readable

• Types/objects from getters - i.e. getter is a factory for the property

Microcontainer metadata

• Annotations

• Anonymous beans and beans as values

Microcontainer Lifecycle/dependency

• Monomorphic injection

• Abstract dependency "write your own dependency"

• Install/Uninstall

Microcontainer deployment

• Schema driven xml

• Use case deployments (simplified deployments)

• Relax xml ordering

• Separate deployment/bean

• Enhance deployment to provide more defaults for beans

XML

• Schema metadata driven - holders, extensible type system, etc.

• Solve the XSD parsing performance

• Remove dependency on Xerces

• Mix and Match different deployments in the same file/deployment

JBoss5 integration (JBoss5HighLevelRoadMap)

• Integrate ServiceController with KernelController

• MBeans gain MC features

• Bootstrap issues MC/AOP/JMX

Examples/Porting

• New pojoized JCA implementation

• JMX implementaton using AOP invocation model

Documentation

• Better getting started guide

• More concrete real world examples

• Reference docs

• ENC

Deployment aspects

• replicated
