Migrated Apache Tomcat configuration elements

In Apache Tomcat, certain configuration required by an application can be in the server.xml, context.xml, or web.xml files, which are located in the Tomcat conf directory. The server.xml and context.xml files can also reference the default tomcat-users.xml file located in the Tomcat conf directory or user-defined configuration files that contain tomcat-users elements. Additional configuration can be in the META-INF/context.xml or WEB-INF/web.xml files of the application.
