word转pdf。。。jacob

long start = System.currentTimeMillis();
ActiveXComponent app = null;
try {
    app = new ActiveXComponent("Word.Application");
    app.setProperty("Visible", false);
    Dispatch docs = app.getProperty("Documents").toDispatch();

// filePath word的路径，，尽量使用绝对路径
    Dispatch doc = Dispatch.call(docs, "Open", filePath, false, true).toDispatch();
// file 获取的是 当前项目路径。。。保存的地址    

filePath = file + "\\wordTemplate\\"+ "商标申请合同.pdf";
    File tofile = new File(filePath);
    if (tofile.exists()) {
        tofile.delete();
    }
    Dispatch.call(doc, "SaveAs", filePath, DocUtil.getWdFormatPDF());
    Dispatch.call(doc, "Close", false);
    long end = System.currentTimeMillis();

} catch (Exception e) {
    System.out.println("Word转PDF出错：" + e.getMessage());
} finally {
    if (app != null) {
        app.invoke("Quit", DocUtil.getWdDoNotSaveChanges());
    }
}

注意 这里jacob要放在 jdk，bin和 jre bin 和 system32 里各一份，注意下载的是64还是32位。（具体另行研究。）
