Dear All, I'm using Drools integrated to Camel trough Rest, but I'm unable to receive objects inserted in the session by the rules, I'm inserting the fact acordos.Acordo and in the "then" section of the rule I create new facts to be returned to my app in this case is the fact acordos.Retorno, but I'm unable to access this facts in the Rest response Does anybody have some clue how to get these objects inserted? Follow bellow what I'm sending, receiving and my rule: Rule Definition: package acordos declare Acordo dataReserva: java.util.Date dataEmbarque: java.util.Date gds: String ciaAerea: String tipoAcordo: String conexao: String origem: String destino: String empresa: String unidade: String cliente: String end declare Retorno codAcordo: String end #generated from Decision Table import teste.*; import java.util.Date; # rule values at C18, header at C13 rule "tabelaTeste(Acordo acordo)_18" salience 65518 when Acordo(getDataReserva().after(new Date("22-Oct-2009")), getDataReserva().before(new Date("31-Dec-2015")), getDataEmbarque().after(new Date("1-Jan-2012")), getDataEmbarque().before(new Date("31-Dec-2012")), gds == "1", ciaAerea == "AA", tipoAcordo == "1", getOrigem() in ("Brasil"), getDestino() in("América do Norte","Brasil","Estados Unidos","Canadá","Ásia","América Central","América do Sul","Mexico","Europa","Caribe")) then System.out.println("teteteetetet"); Retorno _retorno = new Retorno(); _retorno.setCodAcordo("PEB06"); insert(_retorno); end Rest request: curl -v -H "Content-Type: text/plain" --data " <batch-execution lookup=\"ksession1\"> <insert out-identifier=\"message\"> <acordos.Acordo> <dataReserva>2012-01-30 08:00:00.000 -0300</dataReserva> <dataEmbarque>2012-01-30 08:00:00.000 -0300</dataEmbarque> <gds>1</gds> <ciaAerea>AA</ciaAerea> <conexao></conexao> <origem>Brasil</origem> <destino>Brasil</destino> <tipoAcordo>1</tipoAcordo> </acordos.Acordo> <acordos.Retorno> <codAcordo></codAcordo> </acordos.Retorno> </insert> <fire-all-rules out-identifier=\"firedActivations\" /> </batch-execution>" http://localhost:8080/drools-camel-server-5.4.0.Final/kservice/rest/execute Rest Response: < HTTP/1.1 200 OK < Server: Apache-Coyote/1.1 < Date: Tue, 15 May 2012 22:20:00 GMT < Content-Type: text/plain < Content-Length: 528 < * Connection #0 to host localhost left intact * Closing connection #0 <?xml version='1.0' encoding='UTF-8'?><execution-results><result identifier="message"><acordos.Acordo><dataReserva>2012-01-30 11:00:00.0 UTC</dataReserva><dataEmbarque>2012-01-30 11:00:00.0 UTC</dataEmbarque><gds>1</gds><ciaAerea>AA</ciaAerea><tipoAcordo>1</tipoAcordo><conexao></conexao><origem>Brasil</origem><destino>Brasil</destino></acordos.Acordo></result><result identifier="firedActivations"><int>1</int></result><fact-handle identifier="message" external-form="0:2:1717445911:1717445911:2:DEFAULT"/></execution-results> Best Regards, Antonio Anderson Souza <http://174.129.217.139:8080/makecallclient/callme?p=YXNvdXphQHZvaWNlLmJyY...> Blog <http://www.antonioams.com> - Twitter <http://twitter.com/antonioams>- LinkedIn <http://br.linkedin.com/in/antonioams> - Facebook<http://www.facebook.com/antonioams>

Issue while comparing BigDecimal and Long(only while using references)

by sumatheja

Hi, I cam to know that we can compare BigDecimal, Long, Integer interchangeably in the LHS of rule like *when Message(Decimalstatus == Longstatus)* I found that this rule will fire as long as both Decimalstatus and Longstatus Values are same. But when I try to use this feature in the below mentioned way *when Message($dec:Decimalstatus) Message(longstatus == $dec)* This rule doesn't fire even though I have two Message object which satisfy the condition.However, when I try * when Message($dec:Decimalstatus) Message(longstatus == $dec.longValue())* It fires properly. Is this an issue or am I missing anything? Any suggestions for better approach are welcome.Thanks in advance. -- cheers Sumatheja Dasararaju

Unable to share model between different packages in Guvnor 5.0.0

by devan.vanreenen＠gmail.com

Hi there, Please assist. I promote 2 POJO model jars and a declarative model to the global area in Guvnor. I then create a upload a new POJO model jar and declarative model but select not to "create new" but to import the models from global area, however there is nothing in the drop down of available assets to import from global area. Please confirm what I might be doing wrong. Thanks Devan -- View this message in context: http://drools.46999.n3.nabble.com/Unable-to-share-model-between-different...

Re: [rules-users] Different Thread Handling between fireAllRules() and fireUntilHalt()

by totempole

The issue occurs only when fireUntilHalt() is launched in Drools-Spring integration, like this, <drools:ksession id="ksession" type="stateful" name="ksession" kbase="kbase" > <drools:batch> <drools:set-global identifier="droolsServiceUtil" ref="droolsServiceUtil" /> *<drools:fire-until-halt />* </drools:batch> </drools:ksession> When I invoke the same method in Java below, the issue doesn't show up. Could it be a bug in Drools-Spring integration? @Async public void fireRulesUtilHalt() { try { getKsession().fireUntilHalt(); } catch ( ConsequenceException e ) { throw e; } } -- View this message in context: http://drools.46999.n3.nabble.com/Different-Thread-Handling-between-fireA...

How to get list of rules that we modified/added/deleted

by aomkaram

When I add/update/delete the rules in decision table and when I press "save changes" I should get the list of rules I recently added/updated/deleted for doing some validation before I save it. Is there any callback/api to get the rules only that I have modified from last save?
