Hi all,

 

New year -> new mailing list -> new question. 😊

 

I wish everyone on this mailing list a happy and healthy new year!

 

I’m currently writing the blog post about JAX-RS Whiteboard as promised last year. There is one question that came up where I am not sure about the answer. In the specification all JAX-RS Whiteboard Resource examples are configured with PROTOTYPE scope. In chapter 151.4.2 JAX-RS Whiteboard Resource Lifecycle it is explained that stateless services can also be registered as singletons (which is more common in OSGi). If the JAX-RS Whiteboard Resource service has a state (e.g. a JAX-RS context value in a field) it should be PROTOTYPE scope to get a new instance for each request.

 

All examples in the specification are stateless, so my question is, is there a reason/best practice to create all JAX-RS Whiteboard Resource services with PROTOTYPE scope?

 

Mit freundlichen Grüßen / Best regards

Dirk Fauth
