it seems that something new in 5.5.0.CR1 sabotages the ingestion of<br>

Hi,<br>
<br>
This was a good idea. Here is my test case:<br>
<br>
public class TestCompilation {<br>
<br>
private final static FileFilter RULES_FILES_FILTER = new FileFilter() {<br>
@Override<br>
public boolean accept(File pathname) {<br>
return pathname.getName().endsWith(".drl");<br>
}<br>
};<br>
<br>
private void testCompilation() throws FileNotFoundException,<br>
IOException {<br>
KnowledgeBuilderConfiguration configuration =<br>
KnowledgeBuilderFactory.newKnowledgeBuilderConfiguration();<br>
KnowledgeBuilder kbuilder =<br>
KnowledgeBuilderFactory.newKnowledgeBuilder(configuration);<br>
<br>
File folder = new File("src/main/rules/");<br>
for (File file : folder.listFiles(RULES_FILES_FILTER)) {<br>
System.out.println("compiling "+file.getAbsolutePath());<br>
kbuilder.add(ResourceFactory.newFileResource(file.getAbsolutePath()),<br>
ResourceType.DRL);<br>
}<br>
<br>
System.out.println("saving");<br>
ObjectOutputStream out = new ObjectOutputStream(new<br>
FileOutputStream("test.drl.compiled"));<br>
out.writeObject( kbuilder.getKnowledgePackages());<br>
out.close();<br>
}<br>
<br>
private KnowledgeBase testLoad() throws FileNotFoundException,<br>
IOException, ClassNotFoundException {<br>
Properties configProperties = new Properties();<br>
KnowledgeBaseConfiguration knowledgeBaseConfiguration =<br>
KnowledgeBaseFactory.newKnowledgeBaseConfiguration(configProperties);<br>
KnowledgeBase kbase =<br>
KnowledgeBaseFactory.newKnowledgeBase(knowledgeBaseConfiguration);<br>
<br>
ObjectInputStream in = new ObjectInputStream(new<br>
FileInputStream("test.drl.compiled"));<br>
<br>
System.out.println("loading");<br>
kbase.addKnowledgePackages((Collection<KnowledgePackage>) in.readObject());<br>
return kbase;<br>
}<br>
<br>
public static void main(String[] args) throws<br>
FileNotFoundException, IOException, ClassNotFoundException {<br>
TestCompilation testCompilation = new TestCompilation();<br>
testCompilation.testCompilation();<br>
testCompilation.testLoad();<br>
}<br>
}<br>
<br>
The folder src/main/rules consists of a number of .drl files.<br>
Compiling works fine.<br>
This is the output:<br>
<br>
SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".<br>
SLF4J: Defaulting to no-operation (NOP) logger implementation<br>
SLF4J: See <a href="http://www.slf4j.org/codes.html#StaticLoggerBinder" target="_blank">http://www.slf4j.org/codes.html#StaticLoggerBinder</a> for<br>

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

....<br>
<br>
Same issue like in my previous email, different class that cannot be found.<br>
<br>
This works in 5.4.0.Final<br>
<br>
Any clue?<br>
<br>
This seems to me like a really basic thing so either I am missing the<br>
plot somehow or no-one has yet used a locally declared fact classes -<br>
which I think is just not true...<br>
<br>
Regards,<br>
Willem<br>
