JAVA jacob office转换pdf代码

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);
System.out.println("转换文档到PDF..." + toFileName);
File tofile = new File(toFileName);
if (tofile.exists()) {
tofile.delete();
}
Dispatch.call(doc,
"SaveAs",
toFileName, // FileName
wdFormatPDF);
long end = System.currentTimeMillis();
System.out.println("转换完成..用时：" + (end - start) + "ms.");

} catch (Exception e) {
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("E:\\321.doc", "E:\\test_321test.pdf");
}
