Which two are typically found in the WEB-INF folder of a Java web application?

A.
the web application HTML and JSP files

B.
the classes directory containing the compiled classes

C.
the web.xml deployment descriptor

D.
the weblogicserver.xml deployment descriptor

Explanation:
The WEB-INF directory contains the deployment descriptors for the Web application
(web.xml (C) and weblogic.xml) and two subdirectories for storing compiled Java classes (B) and
library JAR files. These subdirectories are respectively named classes and lib. JSP taglibs are
stored in the WEB-INF directory at the top level of the staging directory. The Java classes include
servlets, helper classes and, if desired, precompiled JSPs.
