Method Detail

loadConfigProperties

public static org.apache.felix.utils.properties.Properties loadConfigProperties(File file)
                                                                         throws Exception

Loads the configuration properties in the configuration property file associated with the framework installation; these properties are accessible to the framework and to bundles and are intended for configuration purposes. By default, the configuration property file is located in the conf/ directory of the Felix installation directory and is called "config.properties". The installation directory of Felix is assumed to be the parent directory of the felix.jar file as found on the system class path property. The precise file from which to load configuration properties can be set by initializing the "felix.config.properties" system property to an arbitrary URL.

Parameters:

file - the config file where to load the properties.

Returns:

A Properties instance or null if there was an error.

Throws:

Exception - if something wrong occurs.

loadSystemProperties

public static void loadSystemProperties(File file)
                                 throws IOException

Loads the properties in the system property file associated with the framework installation into System.setProperty(). These properties are not directly used by the framework in anyway. By default, the system property file is located in the conf/ directory of the Felix installation directory and is called "system.properties". The installation directory of Felix is assumed to be the parent directory of the felix.jar file as found on the system class path property. The precise file from which to load system properties can be set by initializing the "felix.system.properties" system property to an arbitrary URL.

Parameters:

file - the Karaf base folder.

Throws:

IOException - if the system file can't be loaded.
