I am now getting this error (note: the error above was not resolved, just a new error now)

Exception in thread "main" java.lang.Error: Unresolved compilation problems:

    KnowledgeBase cannot be resolved to a type

    The method readKnowledgeBase() from the type ProcessTest refers to the missing type KnowledgeBase

    StatefulKnowledgeSession cannot be resolved to a type

    KnowledgeRuntimeLogger cannot be resolved to a type

    KnowledgeRuntimeLoggerFactory cannot be resolved

    WSHumanTaskHandler cannot be resolved to a type

    at com.sample.ProcessTest.main(ProcessTest.java:24)

If I look at the code, I get The import org.drools cannot be resolved.

How do I resolve this? Where can I find the references for this?

Thanks.

I have installed jdk 1.5 and still no joy. The sample project (evaluation) I load has the following error:

The import org.drools cannot be resolved. This is causing errors in the lines of code futher below where the following are used.

KnowledgeBase;

KnowledgeBuilder;

KnowledgeBuilderFactory;

ResourceType;

ResourceFactory;

KnowledgeRuntimeLogger;

Come can I create a library to of these namespaces?

package com.sample;

            logger.close();

        } catch (Throwable t) {

            t.printStackTrace();

        }

    }

    private static KnowledgeBase readKnowledgeBase() throws Exception {

        KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder();

        kbuilder.add(ResourceFactory.newClassPathResource("Evaluation.bpmn"), ResourceType.BPMN2);

        return kbuilder.newKnowledgeBase();

    }

}

I tried to run the ant install.demo command again and launched eclipse with no luck of being able to run the evaluation sample project. the jBPM library was not present. I tried to setup and install Apache ant, JBPM on another work station and was then able to load and run the project with the jBPM library present.
