/** * <p>/*from w w w . j a v a 2s .c o m*/ * This method performs the main task of constructing an framework instance * and starting its execution. The following functions are performed * when invoked: * </p> * <ol> * <li><i><b>Examine and verify command-line arguments.</b></i> The launcher * accepts a "<tt>-b</tt>" command line switch to set the bundle auto-deploy * directory and a single argument to set the bundle cache directory. * </li> * <li><i><b>Read the system properties file.</b></i> This is a file * containing properties to be pushed into <tt>System.setProperty()</tt> * before starting the framework. This mechanism is mainly shorthand * for people starting the framework from the command line to avoid having * to specify a bunch of <tt>-D</tt> system property definitions. * The only properties defined in this file that will impact the framework's * behavior are the those concerning setting HTTP proxies, such as * <tt>http.proxyHost</tt>, <tt>http.proxyPort</tt>, and * <tt>http.proxyAuth</tt>. Generally speaking, the framework does * not use system properties at all. * </li> * <li><i><b>Read the framework's configuration property file.</b></i> This is * a file containing properties used to configure the framework * instance and to pass configuration information into * bundles installed into the framework instance. The configuration * property file is called <tt>config.properties</tt> by default * and is located in the <tt>conf/</tt> directory of the Felix * installation directory, which is the parent directory of the * directory containing the <tt>felix.jar</tt> file. It is possible * to use a different location for the property file by specifying * the desired URL using the <tt>felix.config.properties</tt> * system property; this should be set using the <tt>-D</tt> syntax * when executing the JVM. If the <tt>config.properties</tt> file * cannot be found, then default values are used for all configuration * properties. Refer to the * <a href="Felix.html#Felix(java.util.Map)"><tt>Felix</tt></a> * constructor documentation for more information on framework * configuration properties. * </li> * <li><i><b>Copy configuration properties specified as system properties * into the set of configuration properties.</b></i> Even though the * Felix framework does not consult system properties for configuration * information, sometimes it is convenient to specify them on the command * line when launching Felix. To make this possible, the Felix launcher * copies any configuration properties specified as system properties * into the set of configuration properties passed into Felix. * </li> * <li><i><b>Add shutdown hook.</b></i> To make sure the framework shutdowns * cleanly, the launcher installs a shutdown hook; this can be disabled * with the <tt>felix.shutdown.hook</tt> configuration property. * </li> * <li><i><b>Create and initialize a framework instance.</b></i> The OSGi standard * <tt>FrameworkFactory</tt> is retrieved from <tt>META-INF/services</tt> * and used to create a framework instance with the configuration properties. * </li> * <li><i><b>Auto-deploy bundles.</b></i> All bundles in the auto-deploy * directory are deployed into the framework instance. * </li> * <li><i><b>Start the framework.</b></i> The framework is started and * the launcher thread waits for the framework to shutdown. * </li> * </ol> * <p> * It should be noted that simply starting an instance of the framework is not * enough to create an interactive session with it. It is necessary to install * and start bundles that provide a some means to interact with the framework; * this is generally done by bundles in the auto-deploy directory or specifying * an "auto-start" property in the configuration property file. If no bundles * providing a means to interact with the framework are installed or if the * configuration property file cannot be found, the framework will appear to * be hung or deadlocked. This is not the case, it is executing correctly, * there is just no way to interact with it. * </p> * <p> * The launcher provides two ways to deploy bundles into a framework at * startup, which have associated configuration properties: * </p> * <ul> * <li>Bundle auto-deploy - Automatically deploys all bundles from a * specified directory, controlled by the following configuration * properties: * <ul> * <li><tt>felix.auto.deploy.dir</tt> - Specifies the auto-deploy directory * from which bundles are automatically deploy at framework startup. * The default is the <tt>bundle/</tt> directory of the current directory. * </li> * <li><tt>felix.auto.deploy.action</tt> - Specifies the auto-deploy actions * to be found on bundle JAR files found in the auto-deploy directory. * The possible actions are <tt>install</tt>, <tt>update</tt>, * <tt>start</tt>, and <tt>uninstall</tt>. If no actions are specified, * then the auto-deploy directory is not processed. There is no default * value for this property. * </li> * </ul> * </li> * <li>Bundle auto-properties - Configuration properties which specify URLs * to bundles to install/start: * <ul> * <li><tt>felix.auto.install.N</tt> - Space-delimited list of bundle * URLs to automatically install when the framework is started, * where <tt>N</tt> is the start level into which the bundle will be * installed (e.g., felix.auto.install.2). * </li> * <li><tt>felix.auto.start.N</tt> - Space-delimited list of bundle URLs * to automatically install and start when the framework is started, * where <tt>N</tt> is the start level into which the bundle will be * installed (e.g., felix.auto.start.2). * </li> * </ul> * </li> * </ul> * <p> * These properties should be specified in the <tt>config.properties</tt> * so that they can be processed by the launcher during the framework * startup process. * </p> * @param args Accepts arguments to set the auto-deploy directory and/or * the bundle cache directory. * @throws Exception If an error occurs. **/ @Override public void init(DaemonContext dc) throws Exception { System.out.println("Starting OSGi framework"); String[] args = dc.getArguments(); // Look for bundle directory and/or cache directory. // We support at most one argument, which is the bundle // cache directory.
