This usually indicates incompatible versions of two libraries. Get the most up-to-date jars of drools and try again. Also make sure you don't have multiple versions on the classpath -- View this message in context: http://drools.46999.n3.nabble.com/Hi-people-im-a-drools-newbie-i-get-this...

strict-mode and nested object property access in drools 5.4.0.Final - can i cast?

by radai rosenblatt

hello. I have the following 2 classes: public class ClassWithPayload { private String key; private Object payload; // getters setters etc ommitted } public class PayloadClass { public String someProp; //getters setters etc ommitted } and im trying to get the following rule to compile: rule "Naive Payload Access" when $container : ClassWithPayload(key == "someKey", (payload != null && payload.someProp == "someValue")) then System.err.println("boom"); end which results in the following error: java.lang.AssertionError: Unable to Analyse Expression payload.someProp: [Error: unable to resolve method using strict-mode: java.lang.Object.someProp()] [Near : {... payload.someProp ....}] is there some way for me to cast payload.someProp to the proper class ? (PayloadClass in this case). this is a simplification of a bigger migration issue from drools 5.1 to 5.4 so the payload property has to remain an Object in the general case. there's a casting syntax mentioned here (https://community.jboss.org/wiki/DroolsPatternLanguage) but i take it its not been implemented yet? (or maybe i just cant understand it properly?) i've tried this: rule "Naive Payload Access" when $container : ClassWithPayload(key == "someKey", (payload != null && payload.#PayloadClass(someProp == "someValue"))) then System.err.println("boom"); end but it doesnt compile: java.lang.AssertionError: [8,51]: [ERR 101] Line 8:51 no viable alternative at input '(' in rule "Naive Payload Access" [0,0]: Parser returned a null Package and if i cant cast, how can i get this sort of rule to behave as it did in 5.1.1 ? thanks in advance for any assistance, Radai. -- View this message in context: http://drools.46999.n3.nabble.com/strict-mode-and-nested-object-property-...

No synchronization in Guvnor, between Rest API calls and changeset.xml file

by worldofprasanna

Hi All, I had created a new rule in Decision Table, built the package and created the snapshot using rest api calls from my application. Then I tried to create KnowledgeBase using changeset.xml using the code below, UrlResource urlResourceObj = new UrlResource(new URL(guvnorUrl+"/org.drools.guvnor.Guvnor/package/com.lsi.sort/LATEST/ChangeSet.xml")); agent.applyChangeSet(urlResourceObj); but the package url in the changeset.xml which is, http://localhost:8080/guvnor/org.drools.guvnor.Guvnor/package/com.lsi.sor... doesn t contain the new rule which is added through Rest API call. But when I retrieve the source code of the package using Rest API call, http://localhost:8080/guvnor/rest/packages/com.lsi.sort/source am able to get the New rule. Can anyone explain whether this is the intended behaviour or there is no sync between Rest Api call and the url in changeset.xml. Am using Guvnor 5.4.0.Final Thanks, Prasanna Venkataraman. -- View this message in context: http://drools.46999.n3.nabble.com/No-synchronization-in-Guvnor-between-Re...

Memory Control

by Kang Heng WU

Hi All, The performance of JBoss Expert and Fusion is fine. The throughput of JBoss Expert and Fusion is about 9900 and 4500 messages per second. But we meet the following problems. When the number of handled messages is about 500,000, the performance of Expert is very slow. Its memory is about 300 Mbyte. When the number of handled messages is about 300,000, the performance of Fusion is very slow. Its memory is about 300 Mbyte. What is the problem? How can we solve it?
