RE: Question on notification for internal property change

[Liu Rui <rl...@yahoo.com.cn>]

HI Ian,

I come back to this issue these days.

I find reason why the consumer can not get the notification is the provider
send mal formed notification message.  The message body is as follows;

<soapenv:Body>
	
<xml-fragmentxmlns:fil="http://ws.apache.org/resource/example/filesystem"xml
ns="">
		user files
	</xml-fragment>
</soapenv:Body>


I read the source code pubscrib 1.0.  I think it is because in the notify
method in SubscriptionListener.java, the  m_subscription.getUseNotify(  ) do
not return true so that the wrapMessageWithNotify() method do not be called.

I do know what's wrong with the code given below.  If I use the
notificationproducer.jsp to trigger a value change, every thing is ok.  

Thanks,
Ray.

To clarify, when you say it does not work, do you mean that you subscribed
to the Comment topic but don't receive a notification when you publish one
to that topic? Your code above looks good to me except that it's not
necessary to call both propertyChanged() and publish(), since
propertyChanged() ultimately hands off to publish().

There are errors when using ant compile deploy .

This is expected. Muse 1.0 is based on WSRF and Pubscribe 1.0, and will not
work with WSRF and Pubscribe 1.1 due to some incompatible API changes that
were made in 1.1.
