[rules-dev] Fwd: Fwd: [rules-users] ClassNotFound on class defined in drl with 5.5.0.CR1

Thursday, 25 October 2012

I assume this is the same thing as covered in Marco's "baby sitter" email
and Maciej's fix?

Folks,
it seems that something new in 5.5.0.CR1 sabotages the ingestion of
compiled packages.

Hi,

This was a good idea. Here is my test case:

public class TestCompilation {

     private final static FileFilter RULES_FILES_FILTER = new FileFilter() {
         @Override
         public boolean accept(File pathname) {
             return pathname.getName().endsWith(".drl");
         }
     };

     private void testCompilation() throws FileNotFoundException,
IOException {
         KnowledgeBuilderConfiguration configuration =
KnowledgeBuilderFactory.newKnowledgeBuilderConfiguration();
         KnowledgeBuilder kbuilder =
KnowledgeBuilderFactory.newKnowledgeBuilder(configuration);

         File folder = new File("src/main/rules/");
         for (File file : folder.listFiles(RULES_FILES_FILTER)) {
             System.out.println("compiling "+file.getAbsolutePath());
kbuilder.add(ResourceFactory.newFileResource(file.getAbsolutePath()),
ResourceType.DRL);
         }

         System.out.println("saving");
         ObjectOutputStream out = new ObjectOutputStream(new
FileOutputStream("test.drl.compiled"));
         out.writeObject( kbuilder.getKnowledgePackages());
         out.close();
     }

     private KnowledgeBase testLoad() throws FileNotFoundException,
IOException, ClassNotFoundException {
         Properties configProperties = new Properties();
         KnowledgeBaseConfiguration knowledgeBaseConfiguration =
KnowledgeBaseFactory.newKnowledgeBaseConfiguration(configProperties);
         KnowledgeBase kbase =
KnowledgeBaseFactory.newKnowledgeBase(knowledgeBaseConfiguration);

         ObjectInputStream in = new ObjectInputStream(new
FileInputStream("test.drl.compiled"));

         System.out.println("loading");
kbase.addKnowledgePackages((Collection<KnowledgePackage>) in.readObject());
         return kbase;
     }

     public static void main(String[] args) throws
FileNotFoundException, IOException, ClassNotFoundException {
         TestCompilation testCompilation = new TestCompilation();
         testCompilation.testCompilation();
         testCompilation.testLoad();
     }
}

The folder src/main/rules consists of a number of .drl files.
Compiling works fine.
This is the output:

SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation

The class PossibleSlotLock is just a locally declared fact class. It is
only being used in that particular .drl file. Every .drl file has it's
own package name.

The head of the .drl file:

package vcm.planner.lock.standard;

import java.util.Set;

import com.paconsulting.pase.core.schedule.CurrentTime;
import com.paconsulting.pase.core.duration.FixedDuration;
import com.paconsulting.pase.transport.agents.ScheduleManagingContainer;
import com.paconsulting.pase.transport.agents.movers.Ship;
import com.paconsulting.pase.transport.agents.water.Lock;
import com.paconsulting.pase.transport.agents.water.LockChamber;
import com.paconsulting.pase.transport.agents.base.WaterLevel;
import com.paconsulting.pase.transport.components.action.ActionFactory;
import com.paconsulting.pase.transport.actions.IAction;
import com.paconsulting.pase.transport.components.action.IActionable;
import com.paconsulting.pase.transport.actions.NonTransactionAction;
import com.paconsulting.pase.transport.actions.ExecutableAction;
import com.paconsulting.pase.transport.components.containing.IContainer;
import
com.paconsulting.pase.transport.components.containing.IContainer.UpDown;
import com.paconsulting.pase.transport.components.moving.IMover;
import com.paconsulting.pase.transport.components.moving.TransferSchedule;
import com.paconsulting.pase.transport.components.moving.ToScheduleLock;

declare PossibleSlotLock
     ship : IMover
     chamber : IContainer
     side : IContainer.UpDown
     schedule : TransferSchedule
     eta : double
     at : double
     cause : String
end
....

Same issue like in my previous email, different class that cannot be found.

This works in 5.4.0.Final

Any clue?

This seems to me like a really basic thing so either I am missing the
plot somehow or no-one has yet used a locally declared fact classes -
which I think is just not true...

Regards,
Willem

 It would be interesting to know (and perhaps help to isolate the
problem
 apparently introduced in 5.5.0) if you could try and compile and
 serialize into a single file, and load that in a single readObject.
