Thank you, Wolfgang! :)<br>
<br>
Let's say:<br>
I'm generating StatusMessage objects during the rule processing.
They will be published. But they are also need for further
processing (so they can not be deleted after publishing).<br>
The StatusMessage objects defined as simple POJOs.<br>
<br>
If I'm publishing the StatusMessage objects using a rule like<br>
rule 'publish StatusMessages'<br>
when<br>
$msg : StatusMessage( )<br>
then<br>
// publish<br>
end<br>
In this case every StatusMessage would be send again and again. <br>
My first impression for a solution would be to define a Boolean
field 'send' that signals if the object has been send. But the field
would just be needed for Drools internal processing. So I thought of
defining this additional field using the declare statement. But if I
remember correctly from previous tries, such a things are not
possible because the declare statement with the additional field is
the definition of a new type... Am I right so far?<br>
<br>
Do you have a idea how I can solve my problem of sending an
fact/event just once but keep it in the memory for further
processing?<br>
<br>
Thank sou!<br>

You establish a TopicPublisher as a global declared in your .drl
file.<br>
global TopicPublisher topicPublisher<br>
You must set this from Java code using<br>
TopicPublisher topicPublisher = ...;<br>
statefulKnowledgeSession.setGlobal( "publisher", topicPublisher
)<br>
and then you use it in any RHS code.<br>
<br>
Of course, a TopicPublisher could also be (field of) some fact,<br>
but this shouldn't be necessary for such a central service.<br>

<br>
I've got a simple question.<br>
<br>
How can I get generated facts out of the memory (for
publishing them<br>
using JMS)?<br>
<br>
Thanks :)<br>
