在java中如何调用qtp

日立张

public static void main(String[] args) {
  

//创建 Application 对象
  ActiveXComponent app = new ActiveXComponent("QuickTest.Application");
  Dispatch object = app.getObject();

//启动 QuickTest
  app.invoke("Launch", new Variant[] {});

//使 QuickTest 应用程序可见
  Dispatch.put(app, "Visible", new Variant(true));
  

//设置 QuickTest 运行选项
     Dispatch options = app.getProperty("Options").toDispatch();
     Dispatch run = Dispatch.get(options,"Run").toDispatch();
     Dispatch.put(run,"CaptureForTestResults",new Variant("OnError"));
     Dispatch.put(run,"RunMode",new Variant("Fast"));
     Dispatch.put(run,"ViewResults",new Variant(false));
     Variant openVariant[] = {new Variant("E:\\Program Files\\Mercury Interactive\\QuickTest Professional\\Tests\\Test8"),new Variant(true)};

//以只读模式打开测试
     app.invoke("Open",openVariant);
     
     Dispatch test = Dispatch.get(app,"Test").toDispatch();


//为测试设置运行设置
     Dispatch settings = Dispatch.get(test,"Settings").toDispatch();
     Dispatch settingsRun = Dispatch.get(settings,"Run").toDispatch();
     Dispatch.put(settingsRun,"IterationMode",new Variant("rngIterations"));
     Dispatch.put(settingsRun,"StartIteration",new Variant(0));
     Dispatch.put(settingsRun,"EndIteration",new Variant(4));
     Dispatch.put(settingsRun,"OnError",new Variant("NextStep"));

//创建 Run Results Options 对象
     ActiveXComponent qtResultsOpt = new ActiveXComponent("QuickTest.RunResultsOptions");
     Dispatch qtResultsOptDispatch = qtResultsOpt.getObject();


这个是在网上看到的，但是我怎么用都用不起来，总是说can't map name to dispid: launch
