Method Detail

setUpByXml

public void setUpByXml(java.lang.String filename)
                throws java.lang.Exception

This method is going to call a ControllerParser object to configure controller while parsing file. This method will call setUpRmi() and setUpJmx() as well as setUpVirtualDatabases while parsing.

Parameters:

filename - path to the xml file to parse from

Throws:

java.lang.Exception - if configuration fails

setup

private Controller setup()
                  throws java.lang.Exception

Test if there is a file to take configuration from, if so call setUpByXml()

Returns:

an instanciated and configured object of class Controller

Throws:

java.lang.Exception - if configuration fails

getController

public Controller getController()
                         throws java.lang.Exception

Retrieve the controller associated with this ControllerFactory instance.

Returns:

Controller object. Can be null if this method is called before setup

Throws:

java.lang.Exception - if an error occurs

setUpJmx

public void setUpJmx()
              throws JmxException

Start up the jmx services if enabled.

Throws:

JmxException - an exception
