关于jacob中设置标题的问题

Dispatch.call(selection, "TypeText", "标题"); // 写入标题内容
报错是The method call(Dispatch, String, Object[]) in the type Dispatch is not applicable for the arguments (Dispatch, String, String)
请问这个问题怎样解决

可以参考以下这个

是不是import不会引起的

import com.jacob.activeX.ActiveXComponent;
import com.jacob.com.Dispatch;
import com.jacob.com.Variant;
