轻松架起Java连接COM对象的桥梁

 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(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_full\\sample\\my.doc";//要转换的word文件
  String tpFile = "H:\\Majix-1_2_2_full\\sample\\my.htm";//临时文件
  String otFile = "H:\\Majix-1_2_2_full\\sample\\my.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
 以上是我为解决将 m$ word 转换为 xml 的java程序问题的通用实现的通用方法，其他COM对象也可以一样的解决。如有问题请Email:[email protected]
