Re: [xmlblaster] getting new messages like a subscribtion

Hi Cyrille,

even if you don't start up a client side callback server you need
to configure it in the ConnectQos so that the server establishes
a callback queue. By setting retries='-1' the server never gives
up to reach the client.
I have tried it with the following script:

=======================================================
<!--
  java javaclients.script.XmlScript -requestFile loginLogoutSubscribe.xml
-->
<xmlBlaster>

<connect>
<qos>
<securityService type="htpasswd" version="1.0"><![CDATA[
<user>tester</user>
<passwd>tester</passwd>
]]></securityService>
<persistent>true</persistent>
<session name='tester/1' />
<queue relating='connection'>
<address type="XMLRPC" pingInterval='1000' retries='-1' delay='2000' />
</queue>
<!-- DO THIS: -->
<queue relating='callback' maxEntries='5' maxEntriesCache='2'>
<callback type="XMLRPC" pingInterval='1000' retries='-1' delay='1000' />
</queue>
</qos>
</connect>

<subscribe><key oid="__sys__Login"></key><qos><persistent>false</persistent></qos></subscribe> 

 <wait delay="600000000" />
</xmlBlaster>
=======================================================

Probably you could additionally set

<callback ... dispatcherActive='false' ...

like this the callback framework is not needlessly trying to find the client. 

Marcel,

I've tried you tips, now the connect and subscribe works.
But, on the server side there are messages :

[WARN Thread-6 DispatchConnection-callback:/node/xmlBlaster_192_168_0_151_3412/cl

Here is my Connect Qos :

<qos>
<session name="'+username+'/3" timeout="3600000" maxSessions="10" clearSessions="false" />
<queue relating="connection">
<address type="XMLRPC" pingInterval="5000" retries="-1" delay="1000" />
</queue>
<queue relating="callback" maxEntries="5" maxEntriesCache="2">
<callback type="XMLRPC" pingInterval="5000" retries="-1" dispatcherActive="false" delay="1000"/>
</queue>
</qos>
