java使用jacob word 转pdf

首先我自己的环境是windows xp ,office2007 ,jdk1.5;

1.先下载office2007 能另存为pdf的插件 SaveAsPDFandXPS.exe 安装。(纠结了好久才知道要安装这个插件，否则无法调用SaveAs方法)

2.下载jacob，位置如下：

jacob.jar 放在 E:\jdk1.5.0_14\lib
jacob.dll 放在 E:\jdk1.5.0_14\bin
源代码如下：

package test.jacob;

import java.io.File;

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

public class Test {
    static final int wdFormatPDF = 17;// PDF 格式  
    public void wordToPDF(String sfileName,String toFileName){  
          
        System.out.println("启动Word...");    
        long start = System.currentTimeMillis();    
        ActiveXComponent app = null;
        Dispatch doc = null;
        try {    
            app = new ActiveXComponent("Word.Application");    
            app.setProperty("Visible", new Variant(false));
            Dispatch docs = app.getProperty("Documents").toDispatch(); 
//          doc = Dispatch.call(docs,  "Open" , sourceFile).toDispatch(); 
            doc = Dispatch.invoke(docs,"Open",Dispatch.Method,new Object[] {                  
               sfileName, new Variant(false),new Variant(true) }, new int[1]).toDispatch();             
            System.out.println("打开文档..." + sfileName);
            System.out.println("转换文档到PDF..." + toFileName);    
            File tofile = new File(toFileName);    
            if (tofile.exists()) {    
                tofile.delete();    
            }      
//          Dispatch.call(doc, "SaveAs",  destFile,  17);                  
            Dispatch.invoke(doc, "SaveAs", Dispatch.Method, new Object[] {              
                toFileName, new Variant(17) }, new int[1]);  
            long end = System.currentTimeMillis();    
            System.out.println("转换完成..用时：" + (end - start) + "ms.");              
        } catch (Exception e) {
            e.printStackTrace();
            System.out.println("========Error:文档转换失败：" + e.getMessage());    
        } finally {
            Dispatch.call(doc,"Close",false);
            System.out.println("关闭文档");
            if (app != null)    
                app.invoke("Quit", new Variant[] {});    
            }
          //如果没有这句话,winword.exe进程将不会关闭
           ComThread.Release();   
    }
    public static void main(String[] args) {
        Test d = new Test();
        d.wordToPDF("d:\\ftp\\aaa.docx", "d:\\ftp\\aaa.pdf");
    }

}
