我现在只用一条规则来实现这个决策表。我在规则“Screens_11”中得到“mismatch input'=='，text = parser返回null package]]”错误。这是堆栈跟踪：

public class TestDecisionTable {
    public static void main(String[] args)
    {
     try{
         KieServices ks = KieServices.Factory.get();
         KieContainer kContainer = ks.getKieClasspathContainer();
         KieSession kSession = kContainer.newKieSession("ksession-dtables");

         Screens s1 = new Screens();
         s1.setDeliveryChannel("Y");
         s1.setUsePointsAppl("Y");
         s1.setContactDetails("Y");
         s1.setRiskScore("Y");
         s1.setReasonCode(100);
         s1.setCurrentScreen(303);
         kSession.insert(s1);

         Screens s2 = new Screens(); 
         s2.setDeliveryChannel("Y");
         s2.setUsePointsAppl("Y");
         s2.setContactDetails("Y");
         s2.setRiskScore("Y");
         s2.setReasonCode(101);
         s2.setCurrentScreen(303);
         kSession.insert(s2);    

         Screens s3 = new Screens();
         s3.setDeliveryChannel("Y");
         s3.setUsePointsAppl("Y");
         s3.setContactDetails("Y");
         s3.setRiskScore("Y");
         s3.setReasonCode(102);
         s3.setCurrentScreen(303);
         kSession.insert(s3);

         kSession.fireAllRules();

     }
     catch (Throwable t) {
         t.printStackTrace();
     }
     }
}

任何帮助都将不胜感激。

第8行已加入单元格。不要在约束列之外加入。

尝试使用此代码并使用完整输出报告。

private void testSpreadsheet(){
  File dtf = new File( dtPath );
  InputStream is;
  try {
    is = new FileInputStream( dtf );
    SpreadsheetCompiler ssComp = new SpreadsheetCompiler();
    String s = ssComp.compile( is, InputType.XLS );
    System.out.println( "=== Begin generated DRL ===" );
    System.out.println( s );
    System.out.println( "=== End generated DRL ===" );
  } catch (IOException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
  }
}

以下决策表可能出现什么问题？
