+  <!-- This is a regular spring configuration file defining our server beans. 
+  	   It is very similar to the one used in the mina chat example.  We've 
+       kept the osgi definitions in a separate configuration file so that 
+       this file can easily be used for testing outside of an OSGi environment -->
        
+  <!-- One aspect of the spring-osgi conventions is that this file is contained 
+  	   within the jar/bundle and not easy to change by system administrators 
+  	   without unpacking it and rearchiving it. If this is too inconvienent that 
+  	   a property file mechanism can be offered with the Spring 
+  	   PropertyPlaceholderConfigurer.
+  	   
+  	   For example given a server.properties file exists in the working directory 
+  	   where the OSGi runtime is executed, specifying the following will allow 
+  	   the use of variables ${property-name} through out this file to be replaced 
+  	   by values from the properties file.
+  
+    <bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"

+	      id="propertyConfigurer">
+		<property name="location">
+			<bean class="org.springframework.core.io.FileSystemResource">
+				<constructor-arg value="server.properties"/>
+			</bean>
+		</property>
+	</bean>
+  -->
   <!-- This makes it possible to specify java.net.SocketAddress values 
     (e.g. :1234 below) as Strings.
     They will be converted into java.net.InetSocketAddress objects by Spring.  -->
