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/... 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: org.drools.CheckedDroolsException: Unable to find implementation for BusinessRuleProvider Stack trace: org.drools.compiler.PackageBuilder.addKnowledgeResource(PackageBuilder.java:544) org.drools.builder.impl.KnowledgeBuilderImpl.add(KnowledgeBuilderImpl.java:28) org.drools.agent.impl.KnowledgeAgentImpl.createPackageFromResource(KnowledgeAgentImpl.java:637) org.drools.agent.impl.KnowledgeAgentImpl.addResourcesToKnowledgeBase(KnowledgeAgentImpl.java:889) org.drools.agent.impl.KnowledgeAgentImpl.rebuildResources(KnowledgeAgentImpl.java:704) org.drools.agent.impl.KnowledgeAgentImpl.buildKnowledgeBase(KnowledgeAgentImpl.java:584) org.drools.agent.impl.KnowledgeAgentImpl.applyChangeSet(KnowledgeAgentImpl.java:185) org.drools.agent.impl.KnowledgeAgentImpl.applyChangeSet(KnowledgeAgentImpl.java:168) Any idea what am I missing here? thx -hugo -- View this message in context: http://drools-java-rules-engine.46999.n3.nabble.com/KnowledgeAgent-Unable...
