软件简介

JACOB一个Java-COM中间件.通过这个组件你可以在Java应用程序中调用COM组件和Win32程序库。

示例代码：

import com.ms.com.*;  
import com.ms.activeX.*;

public class DispatchTest  
{  
  public static void main(String[] args)  
  {  
    ActiveXComponent xl = new ActiveXComponent("Excel.Application");  
    Object xlo = xl.getObject();  
    try {  
      System.out.println("version="+xl.getProperty("Version"));  
      System.out.println("version="+Dispatch.get(xlo, "Version"));  
      xl.setProperty("Visible", new Variant(true));  
      Object workbooks = xl.getProperty("Workbooks").toDispatch();  
      Object workbook = Dispatch.get(workbooks,"Add").toDispatch();  
      Object sheet = Dispatch.get(workbook,"ActiveSheet").toDispatch();  
      Object a1 = Dispatch.invoke(sheet, "Range", Dispatch.Get,  
                                  new Object[] {"A1"},  
                                  new int[1]).toDispatch();  
      Object a2 = Dispatch.invoke(sheet, "Range", Dispatch.Get,  
                                  new Object[] {"A2"},  
                                  new int[1]).toDispatch();  
      Dispatch.put(a1, "Value", "123.456");  
      Dispatch.put(a2, "Formula", "=A1*2");  
      System.out.println("a1 from excel:"+Dispatch.get(a1, "Value"));  
      System.out.println("a2 from excel:"+Dispatch.get(a2, "Value"));  
      Variant f = new Variant(false);  
      Dispatch.call(workbook, "Close", f);  
    } catch (Exception e) {  
      e.printStackTrace();  
    } finally {  
      xl.invoke("Quit", new Variant[] {});  
    }  
  }  
}
