+ * A whiteboard service that represents a listener for endpoints. An Endpoint
+ * Listener represents a participant in the distributed model that is interested
+ * in Endpoint Descriptions. This whiteboard service can be used in many
+ * different scenarios. However, the primary use case is to allow a remote
+ * controller to be informed of End Point Descriptions available in the network
+ * and inform the network about available End Point Descriptions. Both the
+ * network bundle and the controller bundle register a Endpoint Listener
+ * service. The controller informs the network bundle about End Points that it
+ * creates. The network bundles then uses a protocol like for example SLP to
+ * announce these local end-points to the network. If the network bundle
+ * discovers a new Endpoint through its discovery protocol, then it sends an End
+ * Point Description to all the End Point Listener services that are registered
+ * (except its own) that have specified an interest in that endpoint.
+ * <p>
+ * Endpoint Listener services can express their scope with the service property
+ * ENDPOINT_LISTENER_SCOPE. This service property is a list of filters. An
+ * Endpoint Description should only be given to a Endpoint Listener when there
+ * is at least one filter that matches the Endpoint Description properties.
+ * given to it. This filter model is quite flexible. For example, a discovery
+ * bundle is only interested in locally originating Endpoint Descriptions. The
+ * following filter ensure that it only sees local endpoints.
+ * <p>
+ * (org.osgi.framework.uuid=72dc5fd9-5f8f-4f8f-9821- 9ebb433a5b72)<br>
+ * In the same vein, a controller that is only interested in remote Endpoint
+ * Descriptions can use a filter like:
+ * <p>
+ * (!(org.osgi.framework.uuid=72dc5fd9-5f8f-4f8f-9821-9ebb433a5b72)) <br>
+ * Where in both cases, the given UUID is the UUID of the local framework that
+ * can be found in the Framework properties. The Endpoint Listener’s scope maps
+ * very well to the service hooks. A controller can just register all filters
+ * found from the Listener Hook as its scope. This will automatically provide it
+ * with all known endpoints that match the given scope, without having to
+ * inspect the filter string. In general, when an Endpoint Description is
+ * discovered, it should be dispatched to all registered Endpoint Listener
+ * services. If a new Endpoint Listener is registered, it should be informed
+ * about all currently known Endpoints that match its scope. If a getter of the
+ * Endpoint Listener service is unregistered, then all its registered Endpoint
+ * Description objects must be removed. The Endpoint Listener models a best
+ * effort approach. Participating bundles should do their utmost to keep the
+ * listeners up to date, but implementers should realize that many endpoints

+Distributed OSGi Calculator Sample
+==================================
+This sample implements a distributed calculator using Distributed OSGi (RFC 119) over SCA.
+
+The README in the samples directory (the directory above this) provides
+general instructions about building and running samples. Take a look there
+first.
+
+On Windows, run
+java -jar ..\..\modules\osgi-3.4.0-v20080605-1900.jar -configuration ..\..\features\configuration -clean -console
+
+On *Unix, run
+java -jar ../../modules/osgi-3.4.0-v20080605-1900.jar -configuration ../../features/configuration -clean -console
+
+You should see the osgi console:

+Sample Overview
+---------------
+The application consists of two OSGi bundles:
+ * The calculator bundle: It provides the calculator service. The service is implemented by a java class that
+ consumes other services to perform the “add”, “subtract”, “multiply” and “divide” operations.
+ * The operations bundle: It provides the add/subtract/multiply/divide services.
+ (See ../samples/dosgi-calculator-operations)

+ by such Contributor that are necessarily infringed by their
+ Contribution(s) alone or by combination of their Contribution(s)
+ with the Work to which such Contribution(s) was submitted. If You
+ institute patent litigation against any entity (including a
+ cross-claim or counterclaim in a lawsuit) alleging that the Work
+ or a Contribution incorporated within the Work constitutes direct
+ or contributory patent infringement, then any patent licenses
+ granted to You under this License for that Work shall terminate

+
+ 4. Redistribution. You may reproduce and distribute copies of the
+ Work or Derivative Works thereof in any medium, with or without

+ include a readable copy of the attribution notices contained
+ within such NOTICE file, excluding those notices that do not
+ pertain to any part of the Derivative Works, in at least one
+ of the following places: within a NOTICE text file distributed
+ as part of the Derivative Works; within the Source form or
+ documentation, if provided along with the Derivative Works; or,
+ within a display generated by the Derivative Works, if and
+ wherever such third-party notices normally appear. The contents
+ of the NOTICE file are for informational purposes only and
+ do not modify the License. You may add Your own attribution
+ notices within Derivative Works that You distribute, alongside
+ or as an addendum to the NOTICE text from the Work, provided
+ that such additional attribution notices cannot be construed
+ as modifying the License.
+
+ You may add Your own copyright statement to Your modifications and
+ may provide additional or different license terms and conditions
+ for use, reproduction, or distribution of Your modifications, or
+ for any such Derivative Works as a whole, provided Your use,
+ reproduction, and distribution of the Work otherwise complies with
+ the conditions stated in this License.
+
+ 5. Submission of Contributions. Unless You explicitly state otherwise,
+ any Contribution intentionally submitted for inclusion in the Work
+ by You to the Licensor shall be under the terms and conditions of

+ WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+ implied, including, without limitation, any warranties or conditions
+ of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A

+ risks associated with Your exercise of permissions under this License.
+
+ 8. Limitation of Liability. In no event and under no legal theory,
+ whether in tort (including negligence), contract, or otherwise,
+ unless required by applicable law (such as deliberate and grossly
+ negligent acts) or agreed to in writing, shall any Contributor be
+ liable to You for damages, including any direct, indirect, special,
+ incidental, or consequential damages of any character arising as a
+ result of this License or out of the use or inability to use the
+ Work (including but not limited to damages for loss of goodwill,
+ work stoppage, computer failure or malfunction, or any and all
+ other commercial damages or losses), even if such Contributor
+ has been advised of the possibility of such damages.
+
+ 9. Accepting Warranty or Additional Liability. While redistributing
+ the Work or Derivative Works thereof, You may choose to offer,
+ and charge a fee for, acceptance of support, warranty, indemnity,
+ or other liability obligations and/or rights consistent with this
+ License. However, in accepting such obligations, You may act only
+ on Your own behalf and on Your sole responsibility, not on behalf
+ of any other Contributor, and only if You agree to indemnify,
+ defend, and hold each Contributor harmless for any liability
+ incurred by, or claims asserted against, such Contributor by reason
+ of your accepting any such warranty or additional liability.

+Distributed OSGi Calculator Sample
+==================================
+This sample implements a distributed calculator using Distributed OSGi (RFC 119) over SCA.
+
+The README in the samples directory (the directory above this) provides
+general instructions about building and running samples. Take a look there
+first.
+
+On Windows, run
+java -jar ..\..\modules\osgi-3.4.0-v20080605-1900.jar -configuration ..\..\features\configuration -clean -console
+
+On *Unix, run
+java -jar ../../modules/osgi-3.4.0-v20080605-1900.jar -configuration ../../features/configuration -clean -console
+
+You should see the osgi console:

+Sample Overview
+---------------
+The application consists of two OSGi bundles:
+ * The calculator bundle: It provides the calculator service. The service is implemented by a java class that
+ consumes other services to perform the “add”, “subtract”, “multiply” and “divide” operations.
+ * The operations bundle: It provides the add/subtract/multiply/divide services.
+ (See ../samples/dosgi-calculator-operations)
