what does class scope means here.
You can access that variable in jspInit and jspDestroy also. While former was accessible inside service method only.
Is it possible to access the same variable through out the application
Technically Yes! Since there is only one instance of a
servlet so this variable will be one for whole application. But it would require a lot of extra stuff and also using context parameter is far better option.
please correct me if I am wrong?
