The WEB-INF directory is part of the directory structure that defines a particular "Web application". The WEB_INF directory contains resources pertaining to the Web application including a web.xml file. Also contained in the WEB-INF directory are the following:
- A deployment descriptor file, called web.xml
- A "lib" directory, designated for JAR files that are automatically added to the Web application's classpath at runtime.
- A "classes" directory designated for any classes needed by the application that are not in a JAR file.
- Any client classes for EJBs packaged in .jar files.
