Hi,

When I use:

subscriptionId1 = client.subscribe(producer,consumer,topic,"//content[text()=\"Hello\"]");
client.unSubscribe(producer,subscriptionId1);

I get the next stack trace:

SubscriptionID received=<wse:Identifier 
xmlns:wse="http://schemas.xmlsoap.org/ws/2004/08/eventing">Xsub1_at_1174497430832</wse:Identifier>
SubscriptionId=<wse:Identifier 
xmlns:wse="http://schemas.xmlsoap.org/ws/2004/08/eventing">Xsub1_at_1174497430832</wse:Identifier>

However, when I use:

subscriptionId1 = client.subscribe(producer,consumer,topic,null);
client.unSubscribe(producer,subscriptionId1);

it works successfully. I don't know what is wrong.

Thank you for your help.
