title: Exception Handling in Model Component
body: <p>I am confused with the following question:</p>
  
  <p>You are implementing a model component. You realize that an IOException might arise if you lose connection to the database. Following are the option:</p>
  
  <ol>
  <li><p>Implement multipathing to provide redundant connectivity to the database, thereby avoiding that risk of connection failure.</p></li>
  <li><p>Provide an error handler page, and use the page directive in the invoking ISP to redirect to that page if the error arises.</p></li>
  <li><p>Use the JSTL  tag to take control if the exception arises.</p></li>
  <li><p>Surround the problem area with a try/catch block and implement appropriate recovery or fallback behavior.</p></li>
  </ol>
  
  <p>I think answer is option no 4 but it's written answer is 3 i don't know how?</p>
