Hi
When you publish a service, you could specify the version info in
service property, for example, publishing a service using blueprint
XML:
<service ref="myMessageDrivenBean" interface="javax.jms.MessageListener">
<service-properties>
<entry key="version" value="1.0" />
</service-properties>
</service>
Or you could do similar thing without using blueprint, using
context.registerService
Dictionary dict = new Hashtable();
dict.put(Constants.VERSION_ATTRIBUTE, "1.0");
sr = context.registerService(MessageListener.class.getName(),
new MyMessageDrivenBean(context), dict);
A client can use filter to specify the exact query it wants, for
example something like below -
String fiter = "(" + Constants.VERSION_ATTRIBUTE + "=1.0")";
Then pass the filter into context.getServiceReferences(clazz, filter)
to get the service reference for the service you are interested.
