SUN Sun Certified Web Component Developer for J2EE 5 Sample Questions:

1. Given:
3. class MyServlet extends HttpServlet {
4. public void doPut(HttpServletRequest req, HttpServletResponse resp) throws
ServletException, IOException {
5. // servlet code here ...
26. }
27. }
If the DD contains a single security constraint associated with MyServlet and its only <http- method> tags and <auth-constraint> tags are:
< http-method>GET</http-method>
< http-method>PUT</http-method>
< auth-constraint>Admin</auth-constraint>
Which four requests would be allowed by the container? (Choose four.)

A) A user whose role is Admin can perform a POST.
B) A user whose role is Admin can perform a GET.
C) A user whose role is Admin can perform a PUT.
D) A user whose role is Member can perform a POST.
E) A user whose role is Member can perform a PUT.
F) A user whose role is Member can perform a GET.

2. What is the purpose of session management?

A) To tell the web container to keep the HTTP connection alive so it can make subsequent requests without the delay of making the TCP connection.
B) To manage the user's login and logout activities.
C) To store information on the server-side between HTTP requests.
D) To store information on the client-side between HTTP requests.

3. Which two JSTL URL-related tags perform URL rewriting? (Choose two.)

A) param
B) redirect
C) url
D) import
E) link

4. 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 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' />";
B) 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' />";
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' />";

5. Given this fragment from a Java EE deployment descriptor:
1 24. <welcome-file>beta.html</welcome-file>
1 25. <welcome-file>alpha.html</welcome-file>
And this request from a browser:
http://www.sun.com/SCWCDtestApp/register
Which statement is correct, when the container receives this request?

A) The container first looks in the register directory for beta.html.
B) The container first looks for a servlet mapping in the deployment descriptor.
C) This deployment descriptor is NOT valid.
D) The container first looks in the register directory for alpha.html.
