BRMS-資源和變更集

我試圖運行一個Drools項目，其中包含JBRMS中創建的所有規則。我有一個401例外，並導致零點。BRMS-資源和變更集

package pop.blah.test; 

import org.drools.KnowledgeBase; 
import org.drools.agent.KnowledgeAgent; 
import org.drools.agent.KnowledgeAgentFactory; 
import org.drools.io.ResourceFactory; 
import org.drools.runtime.StatefulKnowledgeSession; 
import org.drools.definition.type.FactType; 

@SuppressWarnings("restriction") 
public class CarApp { 

    public static void main(String[] args) { 

     KnowledgeAgent kagent = KnowledgeAgentFactory.newKnowledgeAgent("MyAgent5"); 
     kagent.applyChangeSet(ResourceFactory.newUrlResource("http://localhost:8080/jboss-brms/org.drools.guvnor.Guvnor/package/pop.blah.test/CAR")); 
     KnowledgeBase kbase = kagent.getKnowledgeBase(); 
     StatefulKnowledgeSession ksession = kbase.newStatefulKnowledgeSession(); 
     ResourceFactory.getResourceChangeScannerService().start(); 
     try { 
     FactType carType = kbase.getFactType("pop.blah.test", "Car"); 
     Object bmw = carType.newInstance(); 
     carType.set(bmw,"name","My Car"); 
     carType.set(bmw,"make","BMW"); 
     carType.set(bmw,"year", 1977); 
     ksession.insert(bmw); 
     ksession.fireAllRules(); 
     boolean dest = (Boolean) carType.get(bmw, "destroy"); 
     if (dest==true) { 
      System.out.println("I am gona destroy that car!"); 
     } 
     else { 
      System.out.println("I am happy with my car!"); 
     } 
     } 
     catch (Exception E) { 
     E.printStackTrace(); 
     } 
     finally { 
     ksession.dispose(); 
     } 

    } 

}

這是我得到的錯誤。

我得到一個401例外。我是否需要包含屬性文件進行認證與此uri？我的資源具有聲明性模型和規則。一個簡單的規則是，如果汽車的「年」少於1989年，則將「破壞」的值設置爲真。我在某個地方出錯了。有人能幫幫我嗎？

如果你去guvnor，什麼樣的資源指向這個URL？ http://localhost:8080/jboss-brms/org.drools.guvnor.Guvnor/package/org.pci/EPOCH？你從哪裏得到該URL？你使用名爲EPOCH的資源獲得一個名爲org.pci的包嗎？乾杯

我已經編輯了上面的代碼。 URL指向BRMS中的資源。我創建了一個快照並從那裏獲取了URL。 401是一個身份驗證錯誤，那麼這意味着我必須包含屬性文件？如果是的話，我應該把Drools項目放在哪裏？ – aps 2011-12-29 21:26:04

剛纔我添加屬性文件按照這張貼：http://stackoverflow.com/questions/5791025/401-exception-in-java-code?answertab=oldest#tab-top現在我沒有得到401例外，但而是在行的錯誤---對象bmw = carType.newInstance（）; – aps 2011-12-29 22:03:03

您確定您在知識包中包含Car聲明類型嗎？

根據我使用的確切代碼的文檔。我認爲它仍然是身份驗證問題，因爲Car的實例無法創建。知識庫無法指向資源。你能否給我一些可以訪問BRMS資源的代碼？ – aps 2011-12-31 21:00:56
