【问题】JspSmartUpload.jar上传出错：Files' name is invalid or does not exist (1205)

由错误提示可以得知，当JSP提交到servlet后，servlet执行到File file = upload.getFiles().getFile(0);以后就不在执行了

【解决方法】

具体是jsp页面的form需要设置(需要设置enctype和name属性, 不然 servlet找不到file文件)

<form action="unloadServlet" enctype="multipart/form-data"   method="post" >
     文件路径: <input type="file" name="file" >
     <br/>
     <input type="submit" value="上传"/>
    </form>

注：表单中enctype="multipart/form-data "的意思， 是设置表单的MIME编码。jspsmart.jar默认情况，这个编码式是application/x--form-urlencoded，不能用于文件上传；只有使用了multipart/form-data ，才能完整的传递文件数据。jspsmart.jar
