Application Mappings - MACROMEDIA 38000382 - JRun - Mac Getting Started Manual

Each web application running in a JRun server can have one context root mapping and
multiple servlet mappings. You can define the context root in the jrun-web.xml file or let
JRun substitute one for you. JRun determines the context root in the following order:
1 Checks the /WEB-INF/jrun-web.xml file for a context root mapping.
2 If the WAR file is uncompressed, JRun uses the WAR file root directory name. For
example, if the WAR file is deployed in the
jrun_root/servers/samples/worldmusic-war/ directory, JRun uses worldmusic-war as
the context root.
3 If the WAR file is compressed, JRun uses the WAR filename, minus the ".war"
extension. For example, if the web application is contained in techniques.war, JRun
uses "techniques" as the context root.
To use web applications in an optimal manner, you must understand how JRun uses
application mappings and servlet mappings to handle requests for HTML files, JSPs, and
servlets. The following table describes the mappings that the JRun configuration files
define:
Configuration file
default-web.xml
web.xml
jrun-web.xml
application.xml

Application mappings

An application mapping relates a context path to the name and directory path of a web
application. The context path specifies the path prefix associated with a web application
mapping. For a default application (rooted at the base of the web server URL
namespace), the context path is an empty string. For a nondefault application, the
context path starts with a forward slash (/) but does not end with one. For example,
/compass maps request URLs that include /compass to the compass application.
For more information on understanding application mappings, see JRun Programmer's
Guide.
