-   * method on the HTTP request's request line, as specified in [RFC2616] section 5.1. This technique is often referred

+
+Apache Olingo OData Cars service on OSGi
+=================================================
+
+This demo is an OSGi version of the Olingo Cars demo.
+
+Building
+--------
+From the base directory of this sample, the pom.xml file
+is used to build and run the standalone unit test.
+
+```
+  mvn clean install
+```
+
+Running the demo in OSGi
+------------------------
+After building the sample, install the bundle to your Karaf
+container.
+
+If you do not have Karaf installed, download apache-karaf-3.0.3.tar.gz from one of the [mirror sites](http://www.apache.org/dyn/closer.cgi/karaf/3.0.3/apache-karaf-3.0.3.tar.gz) and unpack the archive.
+
+```
+$ wget -N http://ftp.halifax.rwth-aachen.de/apache/karaf/3.0.3/apache-karaf-3.0.3.tar.gz
+$ tar -zxf apache-karaf-3.0.3.tar.gz
+$ cd apache-karaf-3.0.3
+```
+
+#### Starting Karaf
+
+```
+$ bin/karaf
+        __ __                  ____      
+       / //_/____ __________ _/ __/      
+      / ,<  / __ `/ ___/ __ `/ /_        
+     / /| |/ /_/ / /  / /_/ / __/        
+    /_/ |_|\__,_/_/   \__,_/_/         
+
+  Apache Karaf (3.0.3)
+
+Hit '<tab>' for a list of available commands
+and '[cmd] --help' for help on a specific command.
+Hit '<ctrl-d>' or type 'system:shutdown' or 'logout' to shutdown Karaf.
+
+karaf@root()>
+```
+
+#### Note on using Karaf behind a firewall
+
+If you do not have a direct access to the maven central repositories, you need to set Karaf's property
+org.ops4j.pax.url.mvn.repositories to point to your local repository
+
+To use your local repository http://nexus.mycorp.com:8081/nexus/content/groups/build.milestone, run the following commands.
+
+```
+config:edit org.ops4j.pax.url.mvn
+config:property-set org.ops4j.pax.url.mvn.repositories http://nexus.mycorp.com:8081/nexus/content/groups/build.milestone
+config:update
+```
+
+Alternatively, you can edit this property in file etc/org.ops4j.pax.url.mvn.cfg.
+
+For further details, please refer to [Karaf User Guide](http://karaf.apache.org/manual/latest/users-guide/index.html).
+
+#### Install Olingo libs and other depdenent libs
+
+For now, we install the individual bundles one by one. We can define feature olingo-server to install all the bundles at once in the future.
+
+First, to install the depending bundles of olingo, run the following karaf console commands.
+
+```
+feature:install war
+bundle:install -s mvn:commons-codec/commons-codec/1.9
+bundle:install -s mvn:org.apache.commons/commons-lang3/3.3.2
+bundle:install -s mvn:org.codehaus.woodstox/stax2-api/3.1.4
+bundle:install -s mvn:com.fasterxml/aalto-xml/0.9.10
+bundle:install -s 'wrap:mvn:org.antlr/antlr4-runtime/4.1/$Bundle-SymbolicName=antlr4-runtime&Bundle-Version=4.1&Export-Package=org.antlr.v4.runtime*'
+bundle:install -s mvn:com.fasterxml.jackson.core/jackson-core/2.4.1
+bundle:install -s mvn:com.fasterxml.jackson.core/jackson-annotations/2.4.1
+bundle:install -s mvn:com.fasterxml.jackson.core/jackson-databind/2.4.1
+```
+
+Now, install the olingo bundles by running the following commands. Note that
+we assume we are using the patched version regarding OLINGO-632.
+
+```
+bundle:install -s mvn:org.apache.olingo/odata-commons-api/4.0.0-SNAPSHOT
+bundle:install -s mvn:org.apache.olingo/odata-commons-core/4.0.0-SNAPSHOT
+bundle:install -s mvn:org.apache.olingo/odata-server-api/4.0.0-SNAPSHOT
+bundle:install -s mvn:org.apache.olingo/odata-server-core/4.0.0-SNAPSHOT
+```
+
+#### Install this sample bundle
+
+To install this sample bundle, run the karaf console command.
+
+```
+bundle:install -s mvn:org.apache.olingo/odata-server-osgi-sample/4.0.0-SNAPSHOT
+```
+
+Shown below is the output from running the above Karaf console commands.
+
+```
+karaf@root()> feature:install war

+Bundle ID: 109

+```
+
+To verify if the sample is correctly installed and running, use list and web:list to see its bundle status and its web context is registered.
+
+```
