* This constructor creates a framework instance with a specified Map * of configuration properties. Configuration properties are used internally * by the framework to alter its default behavior. The configuration properties * should have a String key and an Object value. The passed * in Map is copied by the framework and all keys are converted to * Strings. *

*

* Configuration properties are generally the sole means to configure the * framework's default behavior; the framework does not typically refer to * any system properties for configuration information. If a Map is * supplied to this method for configuration properties, then the framework * will consult the Map instance for any and all configuration * properties. It is possible to specify a null for the configuration * property map, in which case the framework will use its default behavior * in all cases. *

*

* The following configuration properties can be specified (properties starting * with "felix" are specific to Felix, while those starting with * "org.osgi" are standard OSGi properties): *

*
    *
  • org.osgi.framework.storage - Sets the directory to use as * the bundle cache; by default bundle cache directory is * felix-cache in the current working directory. The value * should be a valid directory name. The directory name can be either absolute * or relative. Relative directory names are relative to the current working * directory. The specified directory will be created if it does * not exist. *
    • *
  • org.osgi.framework.storage.clean - Determines whether the * bundle cache is flushed. The value can either be "none" * or "onFirstInit", where "none" does not flush * the bundle cache and "onFirstInit" flushes the bundle * cache when the framework instance is first initialized. The default * value is "none". *
    • *
  • felix.cache.rootdir - Sets the root directory to use to * calculate the bundle cache directory for relative directory names. If * org.osgi.framework.storage is set to a relative name, by * default it is relative to the current working directory. If this * property is set, then it will be calculated as being relative to * the specified root directory. *
    • *
  • felix.cache.filelimit - The integer value of this string * sets an upper limit on how many files the cache will open. The default * value is zero, which means there is no limit. *
    • *
  • felix.cache.locking - Enables or disables bundle cache locking, * which is used to prevent concurrent access to the bundle cache. This is * enabled by default, but on older/smaller JVMs file channel locking is * not available; set this property to false to disable it. *
    • *
  • felix.cache.bufsize - Sets the buffer size to be used by * the cache; the default value is 4096. The integer value of this * string provides control over the size of the internal buffer of the * disk cache for performance reasons. *
    • *
  • org.osgi.framework.system.packages - Specifies a * comma-delimited list of packages that should be exported via the * System Bundle from the parent class loader. The framework will set * this to a reasonable default. If the value is specified, it * replaces any default value. *
    • *
  • org.osgi.framework.system.packages.extra - Specifies a * comma-delimited list of packages that should be exported via the * System Bundle from the parent class loader in addition to the * packages in org.osgi.framework.system.packages. The default * value is empty. If a value is specified, it is appended to the list * of default or specified packages in * org.osgi.framework.system.packages. *
    • *
  • org.osgi.framework.bootdelegation - Specifies a * comma-delimited list of packages that should be made implicitly * available to all bundles from the parent class loader. It is * recommended not to use this property since it breaks modularity. * The default value is empty. *
    • *
  • felix.systembundle.activators - A List of * BundleActivator instances that are started/stopped when * the System Bundle is started/stopped. The specified instances will * receive the System Bundle's BundleContext when invoked. *
    • *
  • felix.log.logger - An instance of Logger that the * framework uses as its default logger. *
    • *
  • felix.log.level - An integer value indicating the degree * of logging reported by the framework; the higher the value the more * logging is reported. If zero ('0') is specified, then logging is * turned off completely. The log levels match those specified in the * OSGi Log Service (i.e., 1 = error, 2 = warning, 3 = information, * and 4 = debug). The default value is 1. *
    • *
  • org.osgi.framework.startlevel.beginning - The initial * start level of the framework once it starts execution; the default * value is 1. *
    • *
  • felix.startlevel.bundle - The default start level for * newly installed bundles; the default value is 1. *
    • *
  • felix.service.urlhandlers - Flag to indicate whether * to activate the URL Handlers service for the framework instance; * the default value is "true". Activating the URL Handlers * service will result in the URL.setURLStreamHandlerFactory() * and URLConnection.setContentHandlerFactory() being called. *
    • *
  • felix.fragment.validation - Determines if installing * unsupported fragment bundles throws an exception or logs a warning. * Possible values are "exception" or "warning". The * default value is "exception". *
*

* The Main class implements some * functionality for default property file handling, which makes it * possible to specify configuration properties and framework properties * in files that are automatically loaded when starting the framework. If you * plan to create your own framework instance, you may be * able to take advantage of the features it provides; refer to its * class documentation for more information. *

*

* The framework is not actually started until the start() method * is called. *

* This class is a logical abstraction for a bundle archive. This class, * combined with BundleCache and concrete BundleRevision * subclasses, implement the bundle cache for Felix. The bundle archive * abstracts the actual bundle content into revisions and the revisions * provide access to the actual bundle content. When a bundle is * installed it has one revision associated with its content. Updating a * bundle adds another revision for the updated content. Any number of * revisions can be associated with a bundle archive. When the bundle * (or framework) is refreshed, then all old revisions are purged and only * the most recent revision is maintained. *

*

* The content associated with a revision can come in many forms, such as * a standard JAR file or an exploded bundle directory. The bundle archive * is responsible for creating all revision instances during invocations * of the revise() method call. Internally, it determines the * concrete type of revision type by examining the location string as an * URL. Currently, it supports standard JAR files, referenced JAR files, * and referenced directories. Examples of each type of URL are, respectively: *

*
    *
  • http://www.foo.com/bundle.jar
    • *
  • reference:file:/foo/bundle.jar
    • *
  • reference:file:/foo/bundle/
    • *
*

* The "reference:" notation signifies that the resource should be * used "in place", meaning that they will not be copied. For referenced JAR * files, some resources may still be copied, such as embedded JAR files or * native libraries, but for referenced exploded bundle directories, nothing * will be copied. Currently, reference URLs can only refer to "file:" targets. *
