The question 9 of HFSJ mock exam :

Which are true about tag libraries in web applications

a)A TLD file must exist in the /WEB-INF/tlds/ directory
b)A TLD file may exist in any subdirectory of WEB-INF
c)A TLD file may exist in the WEB-INF directory in a JAR file
d)A TLD file may exist in the META-INF directory in a JAR file
e)A TLD file in a JAR file must be located at META-INF/taglib.tld

The given answers are b and d

How the answer is b? I think that only d is correct because tlds cant exist in any directory of WEB-INF. according to page number 476 of HFSJ the container will look into 4 places

[Christophe Verré]

b is correct.

JSP 7.3.4
The container searches for all files with a .tld extension under /WEB-INF or a subdirectory, and inside JAR files that are in /WEB-INF/lib.When examining a
JAR file, only resources under /META-INF or a subdirectory are considered.
The order in which these files are searched for is implementation-specific and
should not be relied on by web applications.
