Head First Servlets and JSP, 2nd Edition

Coffee Cram: Chapter 9 Answers

1. Which is true about TLD files?

   (JSP v2.0 pgs 3-16, 1-160)

   	A.	TLD files may be placed in any subdirectory of WEB-INF.
   	B.	TLD files are used to configure JSP environment attributes, such as scripting-invalid.
   	C.	TLD files may be placed in the META-INF directory of the WAR file.
   	D.	TLD files can declare both Simple and Classic tags, but TLD files are NOT used to declare Tag Files.

   Note

   -Option B is invalid because TLD files configure tag handlers not the JSP environment.

   -Option C is invalid because TLD files are not recognized in the META-INF of the WAR file.

   -Option D is invalid because Tag Files may be declared in a TLD (but it is rare).

2. Assuming the standard JSTL prefix conventions are used, which JSTL tags would you use to iterate over a collection of objects? (Choose all that apply.)

   (JSTL v1.1 pg. 42)

   	A.	<x:forEach>
   	B.	<c:iterate>
   C.	<c:forEach>
   D.	<logic:iterate>
   E.	<logic:forEach> ...
