Your web application uses a simple architecture in which servlets handle requests and then forward to a JSP using a request dispatcher. You need to pass information calculated in the servlet to the JSP for view generation. This information must NOT be accessible to any other servlet, JSP or session in the webapp.
Which two techniques can you use to accomplish this goal? (Choose two)

• A.Use the pageContext object to add request attributes.
• B.Add parameters on the request object.
• C.Add attributes to the session object.
• D.Add parameters to the JSP's URL when generating the request dispatcher.
• E.Add attributes on the request object.

A developer chooses to avoid using singieThreadModel but wants to ensure that data If; updated in a thread safe manner.
Which two can support this design goal? (Choose two)

• A.Store the data in the sarvletContext object.
• B.Store the data in an instance variable.
• C.Store the data in the ServletRequest object.
• D.Store the data in a local variable.
• E.Store the data in the Httpsession object.

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.String ext = context.getInitParameter('licenseExtension')if ( ext == null ) { context.resetInitParameter('licenseExtension' DEFAULT);}
• 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.You cannot do this because context parameters CANNOT be altered programmatically.
• E.String ext = context.getInitParameter('licenseExtension')if ( ext == null ) { context.setInitParameter('licenseExtension' DEFAULT);}
