JACOB是一个JAVA-COM桥，允许你从Java中调用COM自动化组件。它使用JNI调用本机的COM库。 JACOB运行在x86和x64环境中支持32位和64位JVM。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[] {}); } } }
