Default constructor for configurator. This determines the axis2.xml file to be used from the init parameters for the AxisServlet in the web.xml. The order of initialization is according the the following precedence:
• If the parameter axis2.xml.path is present, the value is webapp relative path to be used as the location to the axis2.xml file.
• Otherwise, if the parameter axis2.xml.url is present, the URL is used as the location to the axis2.xml file.
• Otherwise, when both of the above init parameters are not present, file is attempted to be loaded from <repo>/WEB-INF/axis2.xml.
• When none of the above could be found, the axis2.xml is loaded from the classpath resource, the value of DeploymenConstants.AXIS2_CONFIGURATION_RESOURCE.

Parameters:

servletConfig - the ServletConfig object from the AxisServlet. This method is called from the init() of the AxisServlet.

Gets the axis configuration object by loading the repository. The order of initialization is according the the following precedence:
• If the parameter axis2.repository.path is present, this folder is used as the location to the repository.
• Otherwise, if the parameter axis2.repository.url is present, the URL is used as the location to the repository.
• Otherwise, when both of the above init parameters are not present, the web applications WEB-INF folder is used as the folder for the repository.

Loads the services within the repository. When the axis2.repository.path init parameter was present, we just call loadServices() in the deployment engine.
When the axis2.repository.url init parameter was present we load services from the respective URL value of the init parameter.
Otherwise, try to load the services from the /WEB-INF folder within the web application.
