Hi Erik, filters do work,
One warning though, if the service property used to represent the version is an
org.osgi.framework.Version, then it will have different equals and comparison
behaviour than if it is a java.lang.String.
For example the filter "(version=1.0.0)" will match an OSGi Version made with
Version.parseVersion("1.0"), but not the String "1.0".
Regards,
Tim

So filters with the version attribute works with JNDI ! Great !!!
Thanks

Hi Erik,
Continuing Lin's guide:
You should be now able to use something similar to:
"aries:services/javax.jms.MessageListener/(" +
Constants.VERSION_ATTRIBUTE + "=1.0)"
when doing JNDI lookup.
I hope I'm not misstating anything.
Best regards,
Bartek

Hi
When you publish a service, you could specify the version info in
service property, for example, publishing a service using blueprint
XML:
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.

Hello,
first, thanks for your work in the OSGI world !
This is my first question about Aries.
So, when we publish a service, we can specify a version number, ok ?
So, now, if I've published 2 versions of the "same service", how a client
can specify the version he needs when a "IntialContext.lookup" is performed
? Do we need an OSGIfied JNDI ?
Thanks
