[jboss-jira] [JBoss JIRA] Commented: (JBRULES-2043) No decent error message when the scoreDrl doesn't exist (was: Log problems while building the RuleBase)

Dietmar Scheidl commented on JBRULES-2043:
------------------------------------------
In org.drools.solver.config.localsearch.LocalSearchSolverConfig::buildRuleBase() fails:
private RuleBase buildRuleBase() {
...
RuleBaseConfiguration ruleBaseConfiguration = new RuleBaseConfiguration();
RuleBase ruleBase = RuleBaseFactory.newRuleBase(ruleBaseConfiguration);
try {
ruleBase.addPackage(packageBuilder.getPackage());
} catch (Exception e) { // TODO remove me if removed in drools 4.0.1
throw new IllegalArgumentException("scoreDrlList (" + scoreDrlList +
") could not be loaded.", e);
}
...
return ruleBase;
}
The thrown exception does not allow the analysis of the real problem.
In my case packageBuilder.getPackage() fails caused by a error in the rule-file. So
packageBuilder.getErrors() would return the list of problems.
No decent error message when the scoreDrl doesn't exist (was: Log
problems while building the RuleBase)

Key: JBRULES-2043
URL: https://jira.jboss.org/jira/browse/JBRULES-2043
Project: JBoss Drools
Issue Type: Feature Request
Security Level: Public(Everyone can see)
Components: drools-solver
Affects Versions: 5.0.0.M5
Reporter: Dietmar Scheidl
Assignee: Geoffrey De Smet
Fix For: 5.0.0.GA
I startet to experiment with the drools-solver but only got a NullPointerException:
Caused by: java.lang.NullPointerException
at org.drools.common.AbstractRuleBase.addPackages(AbstractRuleBase.java:429)
at org.drools.reteoo.ReteooRuleBase.addPackage(ReteooRuleBase.java:395)
at
org.drools.solver.config.localsearch.LocalSearchSolverConfig.buildRuleBase(LocalSearchSolverConfig.java:166)
at
org.drools.solver.config.localsearch.LocalSearchSolverConfig.buildSolver(LocalSearchSolverConfig.java:137)
at
org.drools.solver.config.XmlSolverConfigurer.buildSolver(XmlSolverConfigurer.java:73)
...
After debugging into this location, I found out that it comes from an error in my
scoreDrl.
The buildSolver-Method should fail with a more helpful exception or the result of the
PackageBuilder should be available to analyse the problems.
