我在没有使用jboss的情况下在eclipse中测试了一个简单的工作流示例（当然是通过在Eclipse中配置jbpm5使其支持jbpm5）

现在我想测试在服务器 jboss 5.1 中运行的 JEE 应用程序（Web 应用程序）中的示例工作流

我在 web 应用程序的源文件夹下制作了这个文件：sample.bpmn，我在下制作了 ProcessMain.java

src\com\sample

ProcessMain.java的源代码

package com.sample;

import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;

import javax.naming.Context;
import javax.naming.InitialContext;

import org.apache.commons.collections.map.HashedMap;
import org.drools.KnowledgeBase;
import org.drools.builder.KnowledgeBuilder;
import org.drools.builder.KnowledgeBuilderFactory;
import org.drools.builder.ResourceType;
import org.drools.io.ResourceFactory;
import org.drools.runtime.StatefulKnowledgeSession;

import com.esprit.ConsoftEJB.daos.RequestDaoRemote;
import com.esprit.ConsoftEJB.daos.UserDaoRemote;
import com.esprit.ConsoftEJB.persistence.Request;

/**
 * This is a sample file to launch a process.
 */
public class ProcessMain {

    private RequestDaoRemote  reqService ;

    private List<Request> requests=new ArrayList<Request>();
public ProcessMain() {
    // TODO Auto-generated constructor stub

}   

public List<Request> getAllRequest()
{
    try {
        Context context=new InitialContext();
        setReqService((RequestDaoRemote) context.lookup("erq"));

    } catch (Exception e) {
        e.printStackTrace();
    }
    return requests=reqService.lisAll();
}

    public static final void main(String[] args) throws Exception {

        validation();


    }

        public static void validation()
        {
            int state=0;
            KnowledgeBase kbase = null;
            try {
                kbase = readKnowledgeBase();
            } catch (Exception e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
            StatefulKnowledgeSession ksession = kbase.newStatefulKnowledgeSession();
            // start a new process instance
            ProcessMain p=new ProcessMain();
            List<Request> listreq=  p.getAllRequest();
            for (int i = 0; i < listreq.size(); i++) {
                state=Integer.parseInt(listreq.get(i).getState());
            System.err.println(listreq.get(i).getState());  
            Map<String,Object> param=new HashMap<String,Object>();
            param.put("etat",state);

            ksession.startProcess("com.sample.bpmn.hello",param);


        }

            }

    private static KnowledgeBase readKnowledgeBase() throws Exception {
        KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder();
        kbuilder.add(ResourceFactory.newClassPathResource("sample.bpmn"), ResourceType.BPMN2);
        return kbuilder.newKnowledgeBase();
    }
    public RequestDaoRemote getReqService() {
        return reqService;
    }
    public void setReqService(RequestDaoRemote reqService) {
        this.reqService = reqService;
    }



    public List<Request> getRequests() {
        return requests;
    }



    public void setRequests(List<Request> requests) {
        this.requests = requests;
    }

}

我测试这个类，她在控制台模式下显示正确的结果

（在 sample.bpmn 文件中设置）

但是当我在使用来自java类ProcessMain.java的方法验证的网页（jsp页面）中制作了一个按钮时

显示此错误

java.lang.ClassNotFoundException: org.drools.builder.KnowledgeBuilderFactory from BaseClassLoader@2cfe4f04{VFSClassLoaderPolicy@6bf5a6af{name=vfsfile:/C:/serveur/jboss-5.1.0.GA/jboss-5.1.0.GA/server/default/deploy/ProjetVrai.war/ domain=ClassLoaderDomain@1cd0437b{name=vfsfile:/C:/serveur/jboss-5.1.0.GA/jboss-5.1.0.GA/server/default/deploy/ProjetVrai.war/ parentPolicy=AFTER_BUT_JAVA_BEFORE parent=ClassLoaderDomain@23b87cc4{DefaultDomain}} roots=[MemoryContextHandler@1284661896[path= context=vfsmemory://5hs4j5g-ahljra-h4wsmcy7-1-h4wsw19q-9y real=vfsmemory://5hs4j5g-ahljra-h4wsmcy7-1-h4wsw19q-9y], FileHandler@367317037[path=ProjetVrai.war/WEB-INF/classes context=file:/C:/serveur/jboss-5.1.0.GA/jboss-5.1.0.GA/server/default/deploy/ real=file:/C:/serveur/jboss-5.1.0.GA/jboss-5.1.0.GA/server/default/deploy/ProjetVrai.war/WEB-INF/classes/], DelegatingHandler@511899134[path=ProjetVrai.war/WEB-INF/lib/commons-beanutils.jar context=file:/C:/serveur/jboss-5.1.0.GA/jboss-5.1.0.GA/server/default/deploy/ real=file:/C:/serveur/jboss-5.1.0.GA/jboss-5.1.0.GA/server/default/deploy/ProjetVrai.war/WEB-INF/lib/commons-beanutils.jar], DelegatingHandler@669255256[path=ProjetVrai.war/WEB-INF/lib/commons-collections.jar context=file:/C:/serveur/jboss-5.1.0.GA/jboss-5.1.0.GA/server/default/deploy/ real=file:/C:/serveur/jboss-5.1.0.GA/jboss-5.1.0.GA/server/default/deploy/ProjetVrai.war/WEB-INF/lib/commons-collections.jar],

因此，显然您的 EE 环境中缺少一个类。确保在你的战争中你有 drools-compiler- .jar 和 jbpm-flow .jar 你能否请提及你正在使用哪个版本的 JBPM？
