Explanation:
A: In WebLogic Server 12c, you can make use of the shared Java EE library feature
in WebLogic Server which provides an easy way to share one or more different types of
modules among multiple enterprise applications. A shared library is a single module
or collection of modules that is registered with the Java EE application container
upon deployment. A shared library could be:
• Standalone EJB module
• Standalone web application module
• Multiple EJB modules packaged in an enterprise application
• Multiple web application modules packaged in an enterprise application
• Single plain JAR file
B:
* A WAR file deployed to WebLogic Server always includes the following files:
One servlet or Java Server Page (JSP), along with any helper classes.
An optional web.xml deployment descriptor, which is a Java EE standard XML document that

describes the contents of a WAR file.
A weblogic.xml deployment descriptor, which is an XML document containing WebLogic Serverspecific elements for Web applications.
A WAR file can also include HTML or XML pages and supporting files such as image and
multimedia files.
