STP/EID Component/EID Developers
I'm working on this bug to add (quickly) generation capabilities for Apache Camel. There will be a tutorial on it at EclipseCon 2008, that's why it's being done quickly :) As I go along, I'm taking some development notes for reproduction here.
EID extracts all the models from the org.eclipse.stp.eid/componentModel directory and puts them into a .cimero2 directory in your home.
Next, each component in the .cimero2 is opened, scanned, and there is an attempt to detect the ESB to which that component belongs to see if it is the same as the one that has been chosen at startup time.
If a component is offered by the chosen ESB, a component model gets created in memory including the name for the component, what ESB it belongs to, the icon for it and the component type. Then it's added to the list of component models, which gets reflected on the palette (see org.eclipse.stp.eid.Parser).
Because of the way this is done, you can add your very own component model definitions in this directory, and they will be available on the palette when the canvas starts up.
