Guvnor - Custom operator problem (Not finding it)

by mattmadhavan

Hello, I have written a custom operator called "inlist" and it works great in 5.4.0 (not in 5.6.0). When I import the rules to Guvnor my rule validation fails with the following error: /[Administration and Timing of RT - Date RT started unknown, assumed started more than 365 days of diagnosis] Unable to determine the Evaluator for ID '*inlist*'/ Any ideas please? Thanks Matt -- View this message in context: http://drools.46999.n3.nabble.com/Guvnor-Custom-operator-problem-Not-find... Sent from the Drools: User forum mailing list archive at Nabble.com.

Drools template declaration in kmodule.xml

by david.berkman

Is there any way to declare a drools template (*.drt) and its data files (in tab delimited or csv or whatever) in a kmodule.xml for publication via Maven? I realize I can use the Workbench to create a 'similar' web template and deploy that as a consumable .jar file, but I get the impression that this web template is not quite the same as a drools template, and if I publish like that and disassemble the resulting jar, that the kmodule.xml present there (if there is one), would not reverse engineer and be applicable to my .drt + .csv files I'm currently loading programmatically. And although programmatic loading works, it's not available to monitoring by a KieScanner, and of dynamically loading any changes thereby. I can create my own monitoring and reloading system, but I'd rather not be reinventing the wheel. All help appreciated, Thanks, David -- View this message in context: http://drools.46999.n3.nabble.com/Drools-template-declaration-in-kmodule-...

I give up, where is drools:execution-node defined??

by dunnlow

I see <drools:execution-node id="node1"/> in the drools server knowledge-services.xml and throughout the documentation. But, my app can't compile because that is undefined. I looked in drools-spring.xsd and spring-beans.xsd (the two namespaces defined in that file), but no joy. Am I just blind?? Anyone know where it is defined?

Workbench on tomcat

by john poole

I'm sure I'm being dense, but I can't reconcile the readme instructions with the file I see in the workbench app: 1. Copy kie-tomcat-integration jar into TOMCAT_HOME/lib *Where is this file? 2. Copy jacc lib into TOMCAT_HOME/lib (javax.security.jacc-api in jboss maven repository) *What is the file name for "jacc lib" and where is it? 3. Add valve configuration into TOMCAT_HOME/conf/server.xml inside Host element as last valve definition <Valve className="org.kie.integration.tomcat.JACCValve" /> 4. Edit TOMCAT_HOME/conf/tomcat-users.xml to include roles and users, make sure there will be 'analyst' or 'admin' roles defined as it's required to be authorized to use kie-wb 5. Edit web.xml and uncomment all entries that are marked with TOMCAT-JEE-SECURITY *There are no entries marked with TOMCAT-JEE-SECURITY in that file. 6. Rename org.uberfire.security.auth.AuthenticationSource to org.uberfire.security.auth.AuthenticationSource-ORIGIN and rename org.uberfire.security.auth.AuthenticationSource-TOMCAT-JEE-SECURITY to org.uberfire.security.auth.AuthenticationSource inside WEB-INF/classes/META-INF/services *There isn't an "uberfire" folder under the "org" folder there. -- View this message in context: http://drools.46999.n3.nabble.com/Workbench-on-tomcat-tp4028507.html Sent from the Drools: User forum mailing list archive at Nabble.com.

Best Solution found but latest solution does not work

by moltenice

Hello all, I am currently trying to use Optaplanner to create a timetable of interviewers, where x students are to be given interviews in a given time slot. The planning variable is Lecturer class, meaning different lecturers can be assigned to different timeslots. Through debugging, I can tell that the planner does optimize (I'm currently using brute force just to be complete for small problems). But the final best solution ALWAYS has the results of the last search the optimizer did, and so the 'best' solution information seems to be lost as soon as the planner does another search. Clearly I'm doing something wrong. Can anybody let me know what the problem is? Thanks a bunch in advance!
