All, First, I apologize long email. I have a few questions on how to use RESTful web Service on Execution Server. I have read through the document and followed the instruction. I think I missed a few critical steps. Here are what I did. 1) Created package, category, rule, a java class (Referral as fact). Class Referral { String homeState; String servviceType; String stateLicenseNumber; … } 2) Used Test Scenarios tool to test rule. Everything worked perfectly. 3) Installed Execution Server in JBoss. 4) Added a mytest.properties file under \drools-5.0-guvnor-standalone\jboss-4.2.3.GA\server\default\deploy\drools-server.war\WEB-INF\classes\ <change-set xmlns='http://drools.org/drools-5.0/change-set'"; xmlns:xs='http://www.w3.org/2001/XMLSchema-instance' xs:schemaLocation='http://drools.org/drools-5.0/change-set drools-change-set-5.0.xsd' > <add> <resource source=http://localhost:8080/DroolsDemo_sfasdfasd.pkg type='PKG' /> </add> </change-set> 5) Add jar file for above java class in lib directory. 6) Created java class to call mytest RESTful service. PostMethod method = new PostMethod("http://localhost:8080/drools-server/knowledgebase/mytest"); method.setRequestHeader("Cache-Control", "no-cache"); method.setRequestHeader("Accept","text/xml"); method.setRequestHeader("Content-Encoding","UTF-8"); try{ File f = new File("Request.xml"); method.setRequestBody(new FileInputStream(f)); }catch(Exception e){ } Request.xml content is: <knowledgebase-request> <globals> </globals> <inOutFacts> <named-fact> <id>testFact</id> <fact class="Drools.ReferralDetail"> <homeState>FL</homeState> <serviceType>HH</serviceType> <stateLicenseNumber></stateLicenseNumber> </fact> </named-fact> </inOutFacts> </knowledgebase-request> I got RuleBase mytest not known or is not valid. Here are my questions: 1) Did I miss any other steps? Anything I did wrong? 2) If I run execution server on different server, where I should put pkg file and how to make necessary changes to mytest.properties? Appreciate your help and Happy Holidays.
