1) What is the purpose of session management?


Developer has used this code within a servlet:

62. if(request.isUserInRole("vip")) {

63. // VIP-related logic here

64. }

What else must the developer do to ensure that the intended security goal is achieved?


Your web application uses a simple architecture in which servlets handle requests and then forward to a JSP using a request dispatcher. You need to pass information calculated in the servlet to the JSP for view generation. This information must NOT be accessible to any other servlet, JSP or session in the webapp. Which two techniques can you use to accomplish this goal?

(Choose two.)


You are creating a JSP page to display a collection of data. This data can be displayed in several different ways so the architect on your project decided to create a generic servlet that generates a comma-delimited string so that various pages can render the data in different ways. This servlet takes on request parameter: objectID. Assume that this servlet is mapped to the URL pattern:/WEB-INF/data.

In the JSP you are creating, you need to split this string into its elements separated by commas and generate an HTML <ul> list from the data.

Which JSTL code snippet will accomplish this goal?

5) You have a use case in your web application that adds several session-scoped attributes. At the end of the use case, one of these objects, the manager attribute, is removed and then it needs to decide which of the other session-scoped attributes to remove. How can this goal be accomplished?


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?



String value = getServletContext().getInitParameter("foo");

in an HttpServlet and a web application deployment descriptor that contains:





Which two are true? (Choose two.)


Given the security constraint in a DD:

101. <security-constraint>

102. <web-resource-collection>

103. <web-resource-name>Foo</web-resource-name>

104. <url-pattern>/Bar/Baz/*</url-pattern>

105. <http-method>POST</http-method>

106. </web-resource-collection>

107. <auth-constraint>

108. <role-name>DEVELOPER</role-name>

109. </auth-constraint>

110. </security-constraint>

And given that "MANAGER" is a valid role-name, which four are true for this security constraint?(Choose four.)

9) Which EL expression evaluates to the request URI?

10) A developer is designing a multi-tier web application and discovers a need to hide the details of establishing and maintaining remote communications from the client. In addition, because the business and resource tiers are distributed, the application needs to minimize the inter-tier network traffic related to servicing client requests. Which design patterns, working together, address these issues?
