You are creating a library of custom tags that mimic the HTML form tags. When the user submits a form that fails validation, the JSP form is forwarded back to the user. The <t:textField> tag must support the ability to re-populate the form field with the request parameters from the user's last request. For example, if the user entered "Samantha" in the text field called firstName, then the form is re-populated like this:
<input type='text' name='firstName' value='Samantha' />
Which tag handler method will accomplish this goal?

• A. public int doStartTag() throws JspException {
  JspContext ctx = getJspContext();
  String value = ctx.getParameter(this.name);
  if ( value == null ) value = "";
  JspWriter out = pageContext.getOut();
  try {
  out.write(String.format(INPUT, this.name, value));
  } (Exception e) { throw new JspException(e); }
  return SKIP_BODY;
  }
  private static String INPUT
  = "<input type='text' name='%s' value='%s' />";
• B. public void doTag() throws JspException {
  ServletRequet request = pageContext.getRequest();
  String value = request.getParameter(this.name);
  if ( value == null ) value = "";
  JspWriter out = pageContext.getOut();
  try {
  out.write(String.format(INPUT, this.name, value));
  } (Exception e) { throw new JspException(e); }
  }
  private static String INPUT
  = "<input type='text' name='%s' value='%s' />";
• C. public int doStartTag() throws JspException {
  ServletRequet request = pageContext.getRequest();
  String value = request.getParameter(this.name);
  if ( value == null ) value = "";
  JspWriter out = pageContext.getOut();
  try {
  out.write(String.format(INPUT, this.name, value));
  } (Exception e) { throw new JspException(e); }
  return SKIP_BODY;
  }
  private static String INPUT
  = "<input type='text' name='%s' value='%s' />";
• D. public void doTag() throws JspException {
  JspContext ctx = getJspContext();
  String value = ctx.getParameter(this.name);
  if ( value == null ) value = "";
  JspWriter out = pageContext.getOut();
  try {
  out.write(String.format(INPUT, this.name, value));
  } (Exception e) { throw new JspException(e); }
  }
  private static String INPUT
  = "<input type='text' name='%s' value='%s' />";

You are creating a web form with this HTML:
11.
<form action="sendOrder.jsp">
12.
<input type="text" name="creditCard">
13.
<input type="text" name="expirationDate">
14.
<input type="submit">
15.
</form>
Which HTTP method is used when sending this request from the browser?

• A. GET
• B. POST
• C. PUT

You are building a dating web site. The client's date of birth is collected along with lots of other information. You have created an EL function with the signature: calcAge(java.util.Date):int and it is assigned to the name, age, in the namespace, funct. In one of your JSPs you need to print a special message to clients who are younger than 25. Which EL code snippet will return true for this condition?

• A. ${funct:age(client.birthDate) < 25}
• B. ${funct:age[client.birthDate] < 25}
• C. ${funct:calcAge[client.birthDate] < 25}
• D. ${funct:calcAge(client.birthDate) < 25}
• E. ${calcAge[client.birthDate] < 25}
• F. ${calcAge(client.birthDate) < 25}

Given the definition of MyServlet:
11.
public class MyServlet extends HttpServlet {
12.
public void service(HttpServletRequest request,
13.
HttpServletResponse response)
14.
throws ServletException, IOException {
15.
HttpSession session = request.getSession(); 16 session.setAttribute("myAttribute","myAttributeValue");
17.
session.invalidate();
18.
response.getWriter().println("value=" +
19.
session.getAttribute("myAttribute"));
20.
}
21.
}
What is the result when a request is sent to MyServlet?

• A. An InvalidSessionException is thrown at runtime.
• B. An IllegalStateException is thrown at runtime.
• C. The string "value=myAttributeValue" appears in the response stream.
• D. The string "value=null" appears in the response stream.
