What is a service provider interface in actual. Does it applies when you want to create a vendor product and expose the service or it can be utilized in the application developer way too.

What condition precedes usage of this.

Does it have any resemblance with Fa├žade pattern?

Please advice.

Thanks,
Avinash

See this blog post describing the pattern. A facade is meant for reducing the number of calls. Service provider (and locator) are for finding an object.

Note: I've seen ServiceLocator as a pattern and that's the one Oracle/the JEE cert references.
