>s test1
Subscribing topic test1
Subscribed key :
<key queryType='XPATH'>
/xmlBlaster/key/SimpleChat[ at canal='test1']
</key>
Here i subscribed to a xpath key
Then i publish a message with that same key:
>test1 hello
Publishing :
<key oid='SimpleChat'>
<SimpleChat canal='test1'/>
</key>
<content><![CDATA[ hello]]></content>
<qos>
<isPublish/>
</qos>
Got the message as expected:
Message from SoEu
<SimpleChat canal='test1'></SimpleChat> hello
The problem is when i publish a message with a different canal
attribute, like this:
>test2 hello
Publishing :
<key oid='SimpleChat'>
<SimpleChat canal='test2'/>
</key>
<content><![CDATA[ hello]]></content>
<qos>
<isPublish/>
</qos>
I receive the message even without having subscribe to messages with
canal set to 'test2'!
Message from SoEu
<SimpleChat canal='test2'></SimpleChat> hello
I'm a doing something wrong here?!

Hi,
Is there a way to dispose of topics stored in the dabase?!
A call to erase() does it.
erase has some QoS to control if pending messages of this topic
in callback queues are still delivered or are disposed as well.
Also is there a way to use a single xmlBlaster for multiple
sessions, that is to say... Let's imagine i have a topic called 'test"
A user would login to a given session of the xmlBlaster server, and
all those in the same session, if they had subscribed to the 'test'
topic would receive the message. Still, another user could login to
the xmlBlaster, in a diferrent session, and subscribe to the same
'test' topic, but all messages published by users in the first
session would not be received by him.
If somebody subscribes to 'test' he will get all messages published to
it,
a topic is not bound to a session or a session group.
But you can use filtering with client tags to
do what you want.

Does something like this exist or do i have to use some client tags
for this?

Hi,
this runs fine here:
java org.xmlBlaster.Main
java javaclients.HelloWorldSubscribe -xpath
"/xmlBlaster/key/SimpleChat[ at canal='hello']"
java javaclients.HelloWorldPublish -oid SimpleChat -clientTags
"<SimpleChat canal='hello'/>" -numPublish 10
Note that the very first publish sets the immutable
meta information of the topic (you SimpleChat tag).
Further publishes won't change this meta information.
It could be possible that your topic existed already wihtout
the 'canal' attribute from some former tests you made.
Have a look into the xmlBlaster dump in the <XmlKeyDom> section.
Please try to delete your persistence store
(remove all in $HOME/tmp/* or ${user.home}${file.separator}tmp
if you use HSQLDB) and restart xmlBlaster.

Hi,
I'm currently having a few problems with XPath subscription...
If i subscribe with a key like :
<key queryType='XPATH'>
/xmlBlaster/key/SimpleChat
</key>
then .. if i publish :
<key oid='SimpleChat'>
<SimpleChat canal='hello'>
</SimpleChat>
</key>
<content><![CDATA[test]]></content>
<qos>
<isPublish/>
</qos>
everything works.. but if i had subscribed with a key like:
/xmlBlaster/key/SimpleChat[ at canal='hello']
i would have not received the message!! Am i missing something here?!
I can subscribe to topics using /xmlBlaster/key[ at oid='SimpleChat']
so what's the problem here?!
Any help will be greatly appreciated.
