| 49 | * A class used for initialization of Turbine without a servlet container. | |
| 50 | * <p> | |
| 51 | * If you need to use Turbine outside of a servlet container, you can | |
| 52 | * use this class for initialization of the Turbine servlet. | |
| 53 | * <p> | |
| 54 | * <blockquote><code><pre> | |
| 55 | * TurbineConfig config = new TurbineConfig(".", "conf/TurbineResources.properties"); | |
| 56 | * </pre></code></blockquote> | |
| 57 | * <p> | |
| 58 | * All paths referenced in TurbineResources.properties and the path to | |
| 59 | * the properties file itself (the second argument) will be resolved | |
| 60 | * relative to the directory given as the first argument of the constructor, | |
| 61 | * here - the directory where application was started. Don't worry about | |
| 62 | * discarding the references to objects created above. They are not needed, | |
| 63 | * once everything is initialized. | |
| 64 | * <p> | |
| 65 | * In order to initialize the Services Framework outside of the Turbine Servlet, | |
| 66 | * you need to call the <code>init()</code> method. By default, this will | |
| 67 | * initialize the Resource and Logging Services and any other services you | |
| 68 | * have defined in your TurbineResources.properties file. | |
| 69 | * | |
| 70 | * @todo Make this class enforce the lifecycle contracts | |
