| Question ID 4647 | During initialization, a servlet finds that the database connection it requires is unavailable. As the system designer, you know that the database start up completes several minutes after the web-container initializes the servlet. How should this be handled? |
| Option A | A. Retry the connection until it is successful, then allow the init() method to complete. |
| Option B | B. Throw a ServletException |
| Option C | C. Throw the IOException |
| Option D | D. Throw an UnavailableException |
| Correct Answer | D |
| Question ID 4648 | A servlet wishes to indicate that it is unable to initialize at the present time, but that the initialization might succeed at some future time. Which is true? |
| Option A | A. This cannot be expressed. A servlet either initializes correctly or fails. |
| Option B | B. This expression is not necessary. If a servlet fails to initialize, the container will try again later each time a request is received that attempts to invoke that servlet. |
| Option C | C. The servlet should delay until it is ready to complete initialization successfully. |
| Option D | D. The servlet should throw an UnavailableException |
| Option E | E. The servlet should throw a servletException |
| Correct Answer | D |
