As far as i know, Brl syntax is kind of "deprecated". Only guvnor should use it. I can add support for brl easily, but i don't know if this is correct or not. Guys? What is your opinion?

hi.all,

I working with drools-5.1.1 and just wanted to change my working
knowledgeagent version, which pulls the package binary from the guvnor, to
use local stored BRL files.

As for what I assumed that the KnowledgeAgent is aware of the different
resource types, I simply exchanged in the change-set.xml the resource
location and type specification accordingly to the BRL ones, like the
following:
                       String ruleFile =
"file://Projects/Workspace/myProject/src/rules/DeadManSwitch.brl";
        String xml = "";
                       xml += "<change-set
xmlns='http://drools.org/drools-5.0/change-set'";
                       xml += "
xmlns:xs='http://www.w3.org/2001/XMLSchema-instance'";
                       xml += "
xs:schemaLocation='http://drools.org/drools-5.0/change-set
http://anonsvn.jboss.org/repos/labs/labs/jbossrules/trunk/drools-api/src/main/resources/change-set-1.0.0.xsd'
>";
                       xml += "    <add>";
                       xml += "         <resource source='" + ruleFile + "'
type='BRL'/>";
                       xml += "    </add>";
                       xml += "</change-set>";

All the other things like setting up the KnowledgeAgent, applying the change
set, a.s.o remained the same, but when executing the program I get the
following exception reported:

SEVERE: Run exception: java.lang.RuntimeException:
org.drools.compiler.DroolsParserException:

Any idea what am I missing here?

thx
