While packaging the Web Application DefaultWebApp for deployment into the WebLogic server ...
While packaging the Web Application DefaultWebApp for deployment into the WebLogic server, the home and remote interfaces of the enterprise beans used by the servlets should reside in which directory?
a. DefaultWebApp/META_INF/classes
b. DefaultWebApp/META_INF/lib
c. DefaultWebApp/WEB_INF/lib
d. DefaultWebApp/WEB_INF/classes
e. DefaultWebApp/classes
Choice D is correct. When packaging a web application create META-INF and WEB-INF subdirectories in the application directory to hold deployment descriptors and compiled Java classes. All servlet classes and helper classes should reside in the WEB-INF/classes subdirectory. The home and remote interface classes for enterprise beans used by the servlets into the WEB-INF/classes subdirectory.
All the HTML files, JSP files, images, and any other files that these Web pages reference should exist in the application directory, maintaining the directory structure for referenced files. The META_INF directory contains the deployment descriptors for the enterprise beans, but not the classes.
