How to add a custom Bean component inside SwitchYard tooling palette in JBDS/Eclipse ?

Issue

• How can users add a custom Bean component to the JBDS/Eclipse plugin pallet that extends Java Bean so later user will be able to use the plugin to expose the custom Java Bean as a WebService?
• If the above approach is not supported then is it possible to find the opensource code for the existing Bean component plugin and to modify it as per user's need? Where is the right place to find the right plugin code?
