About 1: JSP.7.3.1 Identifying Tag Library Descriptors

When deployed directly into a web application, the tag library descriptor files must always be in the WEB-INF directory, or some subdirectory of it. TLD files should not be placed in /WEB-INF/classes or /WEB-INF/lib.

About 2 : check this FAQ.

By looking at this : http://faq.javaranch.com/java/DeclaringListeners

we don't need to declare both HttpSessionBindingListener and HttpSessionActivationListener in DD.

So the answer should be HttpSessionAttributeListner and HttpSessionListner.
correct me if I am wrong.

HttpSessionBindingListener and HttpSessionActivationListener dose not require any declration in web.xml file.
rest are need to be declared through <listener> tag.

for your 1st Query: for E option, in practical world, "resources" will be referred as "name of a folder" where you will put your tld files eg in my project, there ia a folder named "jstl" where other few tld are residing
in short, in \WEB-INF tld get stored

sorry for your 2nd Query for i am just new to web developments

hoping explanation for 1st Q of your will help you out

hi,
generally resources folder are used for jsp, html .... which are placed outside the /WEB-INF. According the convention, the question should not be like this.

Otherwise, tld must be placed inside /WEB-INF.

I am not sure whether it can be placed inside

/WEB-INF/lib or /WEB-INf/classes.

am i correct?

in \WEB-INF\class ----resides---> .class files

D is also correct. TLDs can be in META-INF or a subdirectory of META-INF if deployed in a JAR.

Not in this case. Option D refers to the top-level META-INF, the sibling to WEB-INF as noted by the '/'. The META-INF you are refering to is the lower-level META-INF directory found inside .jar files.
