Best answer

Objects in a JSP, whether explicit or implicit, are accessible within a particular scope. In the case of explicit objects, such as a JavaBean instance created in a <jsp:useBean> action statement, you can explicitly set the scope using the attribute scope=”scopevalue”.

There are four scopes available in JSP:

  1. page” scope – The object is accessible only from within the JSP page where it was created.
  2. request” scopeĀ  – The object is accessible from any JSP page servicing the same HTTP request that is serviced by the JSP page that created the object.
  3. session” scope – The object is accessible from any JSP page sharing the same HTTP session as the JSP page that created the object.
  4. application” scope – The object is accessible from any JSP page used in the same Web application (within any single Java virtual machine) as the JSP page that created the object.
