Objects stored in the portlet application scope session are available to:

Objects stored in the portlet application scope session are accessible to any portlet within the same portlet application. This scope is specific to the portlet application, which means that all portlets deployed as part of that application can share and utilize the objects stored in that session. This feature facilitates communication and data sharing between different portlets that belong to the same application, enabling a cohesive user experience.

When multiple portlets are packaged together as a single portlet application, they can access the same session data, allowing for a more integrated functionality. This is especially useful for scenarios where multiple portlets need to collaborate or share data without duplicating efforts or storage.

The other options suggest broader access rights than what is allowed under this session scope. For example, claiming that any portlet on the same page or within the entire portal application can access the session data would not be accurate, as the session visibility is limited to the portlet application itself, preserving encapsulation and ensuring that data integrity is maintained. Lastly, while an individual portlet can certainly access the data it stored, the premise of the question is about shared access among portlets in the application, reinforcing why the correct answer pertains specifically to the scope of the portlet application rather than being confined to
