Class ConfigLoaderInitializer

java.lang.Object
  com.acciente.induction.init.ConfigLoaderInitializer

public class ConfigLoaderInitializer
extends java.lang.Object

This class manages the loading of a config loader (yes, the config loader itself is configurable, and the parameter specifying its name is in a sense a bootstrap parameter value). This class also defines the names of any config parameters that may defined directly in the web.xml where the dispatcher servlet is defined. There are few parameters that can be defined directly in the web.xml, since most of the configuration used to initialize the displatcher is expected to be in an XML file named using the convention [servlet-name]-induction.xml residing in the same location as the web.xml file. Currently the only parameter that may be defined in the web.xml is one that allows reading the configuration using a custom configuration reader class in which case no [servlet-name]-induction.xml is expected. In fact the [servlet-name]-induction.xml is what is loaded by the default configuration reader implementation. Any parameter are expected to be prefixed by the name of given to the dispatcher servlet. For example if the dispatcher servlet is named myapp, the an example of a parameter name in the web.xml would look like: myapp.config-loader-class
