The WebLogic Server-specific deployment descriptor weblogic.xml.
If your Web application does not contain a weblogic.xml deployment descriptor, WebLogic Server
automatically selects the default values of the deployment descriptor elements.
Note:
A Web archive (WAR file) contains the files that make up a Web application. A WAR file is deployed as
a unit on one or more WebLogic Server instances. 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 Server-
specific elements for Web applications.
* A WAR file can also include HTML or XML pages and supporting files such as image and multimedia
files.
