It's job is to load components -(some of which might also be services) and call their lifecycle -methods. - -The ComponentLoader will enable someone to extend any arbitrary class, -implement the lifecycle interfaces, and use it as a component in the -Turbine family. - -This trick will be immediately useful to enable turbine users to -migrate their Turbine 2.1 services to Fulcrum. There are a few -services which should be changed to components, and this trick should -facilitate that migration as well. - -FIXME: Still need a better idea about what makes a service different -from a component, including examples to illustrate the differences. - -For now we will just load Fulcrum and it can use it's current -configuration file. - -Other 2.1->Fulcrum migration plans: - -jason can swap all the imports with the transformer in maven and then -people will probably have to poke around for a couple minutes. - - -Other implementation goals: - -*tons* of debug logging and *tons* of testing. There's a crude -diagram here: http://www.apache.org/~jvanzyl/diagrams/fulcrum.jpg - -leave the code that is there alone as much as possible and extend the -BaseServiceBroker and implement the required lifecycle interfaces: -'public class Fulcrum extends BaseServiceBroker implements -Configurable, Initializable'. We don't want the lifecycle interfaces -applied directly to the service broker. - - -Longer-term plans: - -let the ComponentLoader reload components without stopping the server. -It will have its own classloader eventually (probably borrowing the -webapp classloader code from catalina). We can look for a -configuration.xml in a standard place in the jar or look at the -manifest and use that to configure the component.
