Its just a matter of wording
lets assume you wrap this application object in a bean
class MyBean
{
private Object m_staticobject;
public Object getStaticObject()
{
return m_staticobject;
}
}
Now using JSP beans in myjspfile.jsp:
1)if we create a "page" instance of MyBean then the next time you call
myjspfile.jsp then a NEW instance will be created.
2)if we create an "application" instance of MyBean then the next time you call
myjspfile.jsp then the ORIGINAL one that you created will be used.
Finally, Yes "application" refers to the specific JSP that is being called NOT
The Application...
