[rules-users] Problem to run

[f203529 at li.facens.br]

Hello!

I’m new with Drools and I follow the documentation to install, but when I
try to run the example Hello World its return an error:

org.drools.RuntimeDroolsException: Unable to load dialect
'org.drools.rule.builder.dialect.java.JavaDialectConfiguration:java'
    at
org.drools.compiler.PackageBuilderConfiguration.buildDialectRegistry(PackageBuilderConfiguration.java:134)

org.drools.compiler.PackageBuilderConfiguration.buildDialectRegistry(PackageBuilderConfiguration.java:130)
    ... 6 more

To try to fix the problem I change the build configuration:

        Properties properties = new Properties();
        properties.setProperty( "drools.dialect.java.compiler",
                                "JANINO" );

        PackageBuilderConfiguration cfg = new PackageBuilderConfiguration(
properties );

        JavaDialectConfiguration javaConf = (JavaDialectConfiguration)
cfg.getDialectConfiguration( "java" );
        assertEquals(JavaDialectConfiguration.JANINO,
javaConf.getCompiler() ); // demonstrate that the compiler is
correctly configured

But it also returns an error:

Someone could explain me how to fix the problem?

Thanks!
