这篇文章将为大家详细讲解有关Java如何连接COM对象，小编觉得挺实用的，因此分享给大家做个参考，希望大家阅读完这篇文章后可以有所收获。

问题是在CSDN上一网友提出的将 m$ word 转换为 XML 的Java程序问题(.NET/expert/topic/1091/1091620.xml)or(http://search.csdn.net/expert/topic/54/5406/2002/10/12/1091620.htm">http://www.csdn.net/expert/topic/1091/1091620.xml)or(http://search.csdn.net/expert/topic/54/5406/2002/10/12/1091620.htm). 现将一种简便的方法详细阐述于下：

1。下在Java-COM连接桥JACOB(http://danadler.com/jacob/),需要jacob.jar和jacob.dll两个文件就可以了。并把jacob.dll所在目录设到PATH。

2。调用程序(Exam_2.java)如下：

import java.io.File;

import com.jacob.com.*;

import com.jacob.ActiveX.*;

public class Exam_2 {

public static void main(String[] args) {

ActiveXComponent app = new ActiveXComponent("Word.Application");//启动word

String inFile = "H:Majix-1_2_2_fullsamplemy.doc";//要转换的word文件

String tpFile = "H:Majix-1_2_2_fullsamplemy.htm";//临时文件

String otFile = "H:Majix-1_2_2_fullsamplemy.xml";//目标文件

boolean flag = false;

try {

app.setProperty("Visible", new Variant(false));//设置word不可见

object docs = app.getProperty("Documents").toDispatch();

Object doc = Dispatch.invoke(docs,"Open", Dispatch.Method, new Object[]{inFile,new Variant(false), new Variant(true)}, new int[1]).toDispatch();//打开word文件

Dispatch.invoke(doc,"SaveAs", Dispatch.Method, new Object[]{tpFile,new Variant(8)}, new int[1]);//作为html格式保存到临时文件

Variant f = new Variant(false);

Dispatch.call(doc, "Close", f);

flag = true;

} catch (Exception e) {

e.printStackTrace();

} finally {

app.invoke("Quit", new Variant[] {});

}

if ( flag ) {

app = new ActiveXComponent("excel.Application");//启动excel

try {

app.setProperty("Visible", new Variant(false));//设置excel不可见

Object workbooks = app.getProperty("Workbooks").toDispatch();

Object workbook = Dispatch.invoke(workbooks,"Open",Dispatch.Method,new Object[]{tpFile,new Variant(false), new Variant(true)}, new int[1]).toDispatch();//打开临时文件

Dispatch.invoke(workbook,"SaveAs", Dispatch.Method, new Object[]{otFile,new Variant(46)}, new int[1]);//以xml格式保存到目标文件

Variant f = new Variant(false);

Dispatch.call(workbook, "Close", f);

} catch (Exception e) {

e.printStackTrace();

} finally {

app.invoke("Quit", new Variant[] {});

try {

File file = new File(tpFile);

file.delete();

} catch (Exception e) {

}

}

}

}

}

3。编译执行(确保jacob.dll在PATH中)

H:mytest>javac -classpath jacob.jar Exam_2.java

H:mytest>java -cp jacob.jar;. Exam_2
