错误:java.lang.NullPointerException 0 file(s) uploaded in the database.

这是全部错误:
An error occurs : com.jspsmart.upload.SmartUploadException: Unable to save file in the DataBase (1130). 0 file(s) uploaded in the database.

去掉rs!=null也不行

没有人会吗?????????????????????????

[breeze517]

应该是你在用上传组件时出了问题

[nboys]

用 jspSmartUpload 组件,不知道有没有人有它来把文件上载到服务器(而不是以文件的形式存储)


等待............................................

顶一下

[mcgovern]

能给出完整的出错信息吗？

[hualong2000]

rs!=null&&rs.next() -> rs.next()

just try.

[nboys]

前一个表单：
<FORM METHOD="POST" ACTION="uploadcheck.jsp" ENCTYPE="multipart/form-data">
<INPUT TYPE="FILE" NAME="FILE1" SIZE="50"><BR>
<INPUT TYPE="SUBMIT" VALUE="Upload">
