I'm just using a stock build from 
<a href="http://www.jboss.org/drools/downloads.html">http://www.jboss.org/drools/downloads.html</a>, and it has 
&lt;drools:execution-node&gt; defined in 5.1.1. When I remove it, I just
 get a error on the next xml tag.<br>
<br>
I tried again with the JBoss AS included with Drools Guvnor Standalone 
5.2.0.M1, copying drools-5.2.0.M1-server.war to 
<a href="http://jboss-5.1.0.GA/server/default/deploy/drools-server.war">jboss-5.1.0.GA/server/default/deploy/drools-server.war</a>, but get the 
following error:<br>
<br>

I&#39;m not sure about this, but I think there is no need to define &lt;drools:execution-node&gt; any more. Please try to remove the definition and all its usages from knowledge-services.xml and see what happens. If somebody else could confirm this behaviour, please let us know.<br>


<br>By the way, did you try to deploy drools-server in a JBoss AS?<br><br>Best Regards,<br clear="all"><br>XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX<br><br>Esteban Aliverti<br>- Developer @ <a href="http://www.plugtree.com" target="_blank">http://www.plugtree.com </a><br>
