prototype-scope

I have clear understanding of the various scopes of Spring beans. But I am looking for some use cases of prototype scope of a bean in enterprise tier projects. It would be great if you can share some real life use cases of the prototype scope (not the request scope). I used prototype beans to declare configured form elements (a textbox configured to validate names, e-mail addresses for example) and get "living" instances of them for every form being created in my webapp. The details are not important, only the principle, that I would summarize this way: There is a class that has many config

I want to know when should i exactly use the prototype scope in Spring? I have understood that singleton returns the same object instance if the bean is requested for. Then why should we consider prototype ? Explanations with examples would help a lot to understand the need for it. RMachnik To be clear simple definitions: Prototype scope = A new object is created each time it is injected/looked up. It will use new SomeBean() each time. Singleton scope = The same object is returned each time it is injected/looked up. Here it will instantiate one instance of SomeBean and then return it each time
