Oracle Java Enterprise Edition 5 Web Component Developer Certified Professional Sample Questions:
Given this fragment from a Java EE deployment descriptor:
124.
<welcome-file>beta.html</welcome-file>
125.
<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.
Given a Filter class definition with this method:
21.
public void doFilter(ServletRequest request,
22.
ServletResponse response,
23.
FilterChain chain)
24.
throws ServletException, IOException {
25.
// insert code here
26.
}
Which should you insert at line 25 to properly invoke the next filter in the chain, or the target servlet if there are no more filters?
- A. request.doFilter(request, response);
- B. chain.forward(request, response);
- C. request.forward(request, response);
- D. chain.doFilter(request, response);
Assume a JavaBean com.example.GradedTestBean exists and has two attributes. The attribute name is of type java.lang.String and the attribute score is of type java.lang.Integer.
An array of com.example.GradedTestBean objects is exposed to the page in a requestscoped attribute called results. Additionally, an empty java.util.HashMap called resultMap is placed in the page scope.
A JSP page needs to add the first entry in results to resultMap, storing the name attribute of the bean as the key and the score attribute of the bean as the value.
Which code snippet of JSTL code satisfies this requirement?
- A. ${resultMap[results[0].name] = results[0].score}
- B. <c:set var="resultMap" property="${results[0].name}"
value="${results[0].score}" /> - C. <c:set var="${resultMap}" key="${results[0].name}"
value="${results[0].score}" /> - D. <c:set var="resultMap" property="${results[0].name}">
${results[0].value}
</c:set> - E. <c:set target="${resultMap}" property="${results[0].name}"
value="${results[0].score}" />
You are developing several tag libraries that will be sold for development of third-party web applications. You are about to publish the first three libraries as JAR files: container-tags.jar, advanced-html-form-tags.jar, and basic-html-form-tags.jar. Which two techniques are appropriate for packaging the TLD files for these tag libraries? (Choose two.)
- A. The TLD must be located within the WEB-INF directory of the JAR file.
- B. The TLD must be located within the META-INF directory of the JAR file.
- C. The TLD must be located within a subdirectory of WEB-INF directory of the JAR file.
- D. The TLD must be located within the META-INF/tld/ directory of the JAR file.
- E. The TLD must be located within a subdirectory of META-INF directory of the JAR file.
- F. The TLD must be located within a subdirectory of META-INF/tld/ directory of the JAR file.
You have built your own light-weight templating mechanism. Your servlets, which handle each request, dispatch the request to one of a small set of template JSP pages. Each template JSP controls the layout of the view by inserting the header, body, and footer elements into specific locations within the template page. The URLs for these three elements are stored in request-scoped variables called, headerURL, bodyURL, and footerURL, respectively. These attribute names are never used for other purposes. Which JSP code snippet should be used in the template JSP to insert the JSP content for the body of the page?
- A. <jsp:insert page='${bodyURL}' />
- B. <jsp:include page='<%= bodyURL %>' />
- C. <jsp:include file='${bodyURL}' />
- D. <jsp:include page='${bodyURL}' />
- E. <jsp:insert file='${bodyURL}' />
- F. <jsp:insert page='<%= bodyURL %>' />
