MVEL raising errors for declared types when there is a package import (import x.y.x.*)
--------------------------------------------------------------------------------------
Key: JBRULES-2244
URL: https://jira.jboss.org/jira/browse/JBRULES-2244
Project: Drools
Issue Type: Bug
Security Level: Public (Everyone can see)
Components: drools-compiler, drools-core
Affects Versions: 5.0.1.FINAL, 5.0.0.FINAL
Reporter: Edson Tirelli
Assignee: Edson Tirelli
Fix For: 5.1.0.M1
The following DRL:
===================================================
package org.drools.examples.broker
import org.drools.examples.broker.model.*;
declare Statistics
symbol : String @key()
average : double
end
rule "Setup statistics"
when
$c : Company( $s : symbol )
not( Statistics( symbol == $s ) )
then
Statistics s = new Statistics();
s.symbol = $s;
insert( s );
end
===================================================
Generates the error:
-----------------------------
BuildError: Unable to build expression for 'consequence': Failed to compile: 1 compilation error(s):
- (1,10) unqualified type in strict mode for: Statistics ' Statistics s = new Statistics();
s.symbol = $s;
insert( s );
' broker.drl drools-examples-fusion/src/main/rules line 42 Drools Error
-----------------------------
But if we change the import to:
===================================================
import org.drools.examples.broker.model.Company
import org.drools.examples.broker.model.StockTick
import org.drools.examples.broker.model.SuddenDropEvent
===================================================
Everything works just fine.

Key: JBRULES-1801
URL: https://jira.jboss.org/jira/browse/JBRULES-1801
Project: JBoss Drools
Issue Type: Feature Request
Security Level: Public (Everyone can see)
Components: drools-ant
Affects Versions: 4.0.7
Reporter: Juergen none
Assignee: Mark Proctor
drools-4.0.7:
Original error in build.xml:
/home/juergen/workspace/eclipse/kusss-dev/build.xml:777: RuleBaseTask failed: Unable to load dialect 'org.drools.rule.builder.dialect.java.JavaDialectConfiguration:java'
Traceback to:
org.drools.compiler.PackageBuilderConfiguration, line 154+:
Class cls = classLoader.loadClass( dialectClass );
DialectConfiguration dialectConf = (DialectConfiguration) cls.newInstance();
cls is org.drools.rule.builder.dialect.java.JavaDialectConfiguration, but loaded via classloader given in drools compile ant task property classpathref, while DialectConfiguration is loaded via ant tool classpath used for taskdef
-->
java.lang.ClassCastException: org.drools.rule.builder.dialect.java.JavaDialectConfiguration
interim fix:
make sure drools-compiler.jar is not in classpath of classloaderref
suggested fix:
Class cls = DialectConfiguration.class.getClassLoader().loadClass( dialectClass );
