1.先下载office2007 能另存为pdf的插件 SaveAsPDFandXPS.exe 安装   
  
2.附件提供了jacob1.9的下载   
  
3.这点很重要也是耗时我最久的就是jacob.dll与jacob.jar的存放位置;位置不对则会出现app.getProperty("Documents").toDispatch()这句话无法正常执行;   
  
位置如下文件存放在jdk的 jre 下 例如我这边是   
jacob.jar 放在 E:\\jdk1.5.0\_14\\jre\\lib\\ext   
jacob.dll 放在 E:\\jdk1.5.0\_14\\jre\\bin   
下能正常执行;

按网上说的 放在windows\\system32下则会出现错误

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" , sfileName).toDispatch();
                System.out.println("打开文档..." + sfileName);

                    tofile.delete();

                Dispatch.call(doc,

            } finally {

            	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("E:\\321.doc", "E:\\test_321test.pdf");
    	}
