请教该怎么在java中去得outData返回的值？

Question

jacob操作dll时，怎么取ref回调函数返回的值？如果有其他更好的方法操作DLL，求指导啊~~
DLL方法：int BUSINESS_HANDLEAPI(string businessCode, string inputData, ref string outData);

我现在是这样写的
ActiveXComponent dotnetCom = null;
dotnetCom = new ActiveXComponent("CInterface.Handler");
String outData="";
Variant var = Dispatch.call(dotnetCom,"BUSINESS_HANDLE","00","QXWEB",outData);
System.out.println("执行结果："+var.toString());
System.out.println("返回的值："+outData);

Answer 1

Variant outData = new Variant("value", true); //这样应该就是ref string了Variant var = Dispatch.call(dotnetCom,"BUSINESS_HANDLE","00","QXWEB",outData);System.out.println("返回的值："+outData.getStringRef());
