Method Detail

getInitializedContextManager

private static ContextManager getInitializedContextManager(org.apache.avalon.framework.context.Context initParameters,
                                          org.apache.avalon.framework.logger.Logger logger)

Throws:

java.lang.Exception

createLoggerFromContext

protected org.apache.avalon.framework.logger.Logger createLoggerFromContext(org.apache.avalon.framework.context.Context initParameters)

                throws java.lang.Exception

Initialize the ContainerManager

Specified by:

initialize in interface org.apache.avalon.framework.activity.Initializable

Throws:

java.lang.Exception

initializeContainer

protected void initializeContainer()
                            throws org.apache.avalon.fortress.InitializationException

Throws:
