Oracle Java Enterprise Edition 5 Web Component Developer Certified Professional Sample Questions:
1. Assume the custom tag my:errorProne always throws a java.lang.RuntimeException with the message "File not found."
An error page has been configured for this JSP page.
Which option prevents the exception thrown by my:errorProne from invoking the error page mechanism, and outputs the message "File not found" in the response?
A) <c:try>
<my:errorProne />
<c:catch var="ex" />
${ex.message}
</c:try>
B) <c:try catch="ex">
<my:errorProne />
</c:try>
${ex.message}
C) <c:catch var="ex">
<my:errorProne />
</c:catch>
${ex.message}
D) <my:errorProne>
<c:catch var="ex">
${ex.message}
</c:catch>
</my:errorProne>
E) <c:try>
<my:errorProne />

2. Squeaky Beans Inc. hired an outside consultant to develop their web application. To finish the job quickly, the consultant created several dozen JSP pages that directly communicate with the database. The Squeaky business team has since purchased a set of business objects to model their system, and the Squeaky developer charged with maintaining the web application must now refactor all the JSPs to work with the new system. Which pattern can the developer use to solve this problem?
A) Service Locator
B) Transfer Object
C) Business Delegate
D) Intercepting Filter
3. Given this fragment in a servlet:
23.
if(req.isUserInRole("Admin")) {
24.
// do stuff
25.
}
And the following fragment from the related Java EE deployment descriptor:
812.
<security-role-ref>
813.
<role-name>Admin</role-name>
814.
<role-link>Administrator</role-link>
815.
</security-role-ref>
900.
<security-role>
901.
<role-name>Admin</role-name>
902.
<role-name>Administrator</role-name>
