[jboss-dev-forums] [Design of EJB 3.0] - Re: Component Proposal - Configurable Service Locator

[ALRubinger]

Going to bring this one back and continue development looking forward.

I'm looking to limit the scope (for this first phase) of this component to the following points, which I find lacking in the JEE5 Spec for Application Clients.  Eventually I'd like to work this into the Client Container/Deployer as a JBoss extension to the spec - I'm not looking to compete, but enhance.

* Support N Remote Hosts

* Provide programmatic access to remote services/beans (non-injected)

* Allow lookup outside of "main" class

anonymous wrote : EE9.4, Second Paragraph:
  | Injection is also supported for the application client main class.

* Allow runtime lookup

anonymous wrote : EE9.4, Second Paragraph:
  | Injection occurs before the main method is called.

* Provide caching facility for non-SFSB

* Dont restrict to "java:" namespace

anonymous wrote : EE9.4, First Paragraph:
  | Application clients use the java: JNDI namespace to access these items.

The moving parts I'm proposing and will be working on:

Client-side Library

Will be charged with:

* Performing lookups
* Caching
* Requesting of the configured hosts which services are available

This is currently being re-written from a working implementation I've been using for the past year or so, and is housed in "projects/ejb3/trunk/locator".  There is no formal build or POM as it stands, but I'll be adding these shortly when things are more stable and the refactoring has progressed.

EJB3Registrar

I believe this speaks to Bill's points about determining JNDI bindings, but also addresses a cross-reference to the business interfaces implemented by the EJB.  Will be implemented as a POJO and deployed in ejb3-deployers-beans.xml; also to be exposed as an MBean for outside access.

Integration

On successful deployment of an EJB3 Deployable Unit (in "deploy" of EJBStage2Deployer?) , register with the new EJB3Registrar the EJBContainer and draw relationships between the implemented business interfaces and the resultant JNDI Addresses.  Haven't fleshed this out yet.
