Method Detail


public void configure(Configuration config)
               throws ConfigurationException

Process the configuration and set up the components and their mappings. At this point, all components are prepared and all mappings are made. However, nothing is initialized.

The configuration format follows a specific convention:

Please note: each configuration element must have a unique id. If a configuration element does not have a unique id, it will not be treated as a component. This id is used later as a hint when there is more than one implementation of a role.

The first component encourted which implements a specific role becomes the default implemenation of that role. This can be changed by the default attribute in this configuration.

     <component id="default-connection"

       <!-- Component specific configuration -->

     <jdbc-data-source id="another-connection">

         <!-- Component specific configuration -->


Specified by:
configure in interface Configurable
config - The configuration element to translate into the list of components this impl managers.
ConfigurationException - if the configuration is not valid


protected void interpretProxy(java.lang.String proxyType)
                       throws ConfigurationException
Interpret the ProxyManager type from the configuration element.
