Hi.

I'll assume we are talking about RAP 2.0.
There are three ways to register the resources: The
ApplicationConfiguration[1] (non-workbench applications only), the
org.eclipse.rap.ui.resources extension point (workbench applications
only) or using the ResourceManager[2] directly.
Using ApplicationConfiguration is simple, but then the resource
registration is part of your application instead of your custom widget.
Using the ResourceManager (e.g. in the custom widgets constructor) is
more flexible. But then you need to check first if the resource is
already registered, so it's not registered multiple times.
You also need deliver the JS to the client (except when using the
extension point), which can be done with the new JavaScriptLoader[3]
service. Here it is not necessary to check if the content was already
loaded, JavaScriptLoader already does that.

I would suggest to have a separate bundle used by the custom widgets. It
will have a util class that uses ResourceManager and JavaScriptLoader to
ensure the library is registered and loaded on the client. The custom
widgets could then call something like: JQuery.ensure();
If you have trouble with the details, just ask me.
Greetings,
Tim
