Q19 Single choice

You have built a web application that you license to small businesses. The webapp uses a context parameter, called licenseExtension, which enables certain advanced features based on your client's license package. When a client pays for a specific service, you provide them with a license extension key
that they insert into the <context-param> of the deployment descriptor. Not every client will have this context parameter so you need to create a context listener to set up a default value in the licenseExtension parameter.

Which code snippet will accomplish this goal?

A
You cannot do this because context parameters CANNOT be altered programmatically.
B
String ext = context.getParameter('licenseExtension');if ( ext == null ) {context.setParameter
('licenseExtension', DEFAULT);}
C
String ext = context.getAttribute('licenseExtension');if ( ext == null ) {context.setAttribute
('licenseExtension', DEFAULT);}
D
String ext = context.getInitParameter('licenseExtension');if ( ext == null ) {context.resetInitParameter
('licenseExtension', DEFAULT);}
E
String ext = context.getInitParameter('licenseExtension');if ( ext == null ) {context.setInitParameter
('licenseExtension', DEFAULT);}
