Summary: Calling static Java method from DMN model (Drools Business Central)
Key: DROOLS-5577
URL: https://issues.redhat.com/browse/DROOLS-5577
Project: Drools
Issue Type: Bug
Components: DMN Editor, dmn engine
Affects Versions: 7.40.0.Final
Reporter: Kristina Mandekic
Assignee: Guilherme Gomes
Attachments: Artifacts.PNG, Artifacts0.PNG, DroolsNewTypes5-0.0.1-SNAPSHOT.jar, dependencies.PNG, stdev 0.PNG, stdev 1.PNG
When calling static Java method {{stdev_a}} (which I created in a new Java Maven project) from Drools Business Central DMN project/model, I'm getting following error:
{code:java}
DMN: Error compiling Java function 'stdev' on node 'stdev': Error resolving external function as defined by: function(val) external { java: { class: ""com.samplea.drools.DroolsNewTypes5.StandardDeviationA"", method signature: ""stdev_a(java.lang.Number)"" }} (DMN id: _3B4B6CBE-847B-4488-8754-214F506BBB48, Error compiling the referenced FEEL expression){code}
Also, how to view logs of DMN model when it has build errors?

> *Motivation*: a DMN decision table can be evaluated faster than naive algorithm by translating it into a Rete/Phreak, but the current kie7 approach is suffering from performance bottleneck artificially induced by use of kie7 rule units, which provide more harm than benefit to perfomance (performance is actually worst for most "realistic" cases).
> *Goals*: a POC to understand what’s need to be done to support the alpha network compiler (wihout kie7 rule units) in DMN. We currently estimate it will take us 1 to 2 summer sprints and the output will be more epics to implement this feature.
> *Impact*: alpha network compiler code refactors for the better use of.
> One part of the POC was to hard-code the alpha network for a specific table ([DROOLS-4566]) the remained of the poc is to generalize the approach further to fully assess the impacts thanks to the poc.
