Class AvatarsConfigManager

java.lang.Object
  jautil.install.AvatarsConfigManager

public class AvatarsConfigManager
extends java.lang.Object

The purpose of an AvatarsConfigManager is to ensure that the JA_HOME preferences key is properly defined, so that a JA app has access to the necessary avatar definition files.

An instance of this class does its main work in the establishJAHome() method. This method checks whether there is a valid local setting for the JA_HOME key, and if not it either establishes a valid remote setting for the key or, subject to user approval, downloads the necessary files and establishes a valid local setting for it. The user can specify the base URL for remote avatar definition files by setting the ja.remote.base.url system property. If this property is not set, an internal default is used. This default is obtained by appending the current JASigning version tag to the stem http://www.visicast.cmp.uea.ac.uk/eSIGN/jasigning/, as defined in the DeploymentParameters class.
