Hi ichy,
Thanks for your response.
My html code is:
<form name="frmNTest" enctype="MULTIPART/FORM-DATA" method="post"
action="test.jsp">
<input type=hidden name=hfrmID value="frmTest">
<input type=hidden name=hfrmActionID value="uploadFiletoServer">
<table width="98%" border=0>
<tr>
<td height=60><img src="/images/null.gif" height=15></td>
</tr>
<tr>
<td height=50><img src="/images/null.gif" height=15></td>
</tr>
<tr>
<td>Select File</td>
<td><input type="file" name="updfilename">
</td>
</tr>
<tr>
<td colspan="2"><div align="center">
<input type="submit" name=Submit value="Upload">
</div></td>
</tr>
</table>
*******************************
This is in test.jsp:
<%
UploadFile up = new UploadFile();
up.doUpload(request,response);
%>
***********************************
This is what I get in the ServletInputStream.
Content-Disposition:form-data; name= "hfrmActionID"
uploadFiletoServer
----------------------------- 7d6106f7041a
Content-Disposition:form-data;name="lstReg"
test2
----------------------------- 7d6106f7041a
Content-Disposition:form-data;name="updfilename";filename="Test.xls"
Content-Type:application/vnd.ms-excel
??????
I see a whole bunch of invalid characters and question marks and then I see the
contents of the file, and then:
-----------------------------7d6106f7041a
Content-Disposition:form-data; name="Submit"
Upload
-----------------------------7d6106f7041a--
*******************************
Now I am getting the exception:
2006.29.03 14:01:36 io error = java.io.IOException: Unable to read entire
header; -1 bytes read; expected 512 bytes
thanks, AN

hi, natu.
i haven't got a time to make test code to verify my opinion, but
post this message if it helps.
i assume request means HttpServletRequest.
have you tried to examine what is uploeded by looking at
the content of request.getInputStream() ?
if the html form is like below
-- html start -------
<form action="/servlet/UploadServlet" enctype="multipart/form-data"
method="POST">
<input type="hidden" name="submitter" value=username><br>
<input type="file" name="Uploaded file"><br>
<input type="submit" value="Send">
</form>
-- html end -------
then the content sent to server would be
-- content start ------
Content-Type: multipart/form-data; boundary=
---------------------------10265533117308
-----------------------------10265533117308
content-disposition: form-data; name="submitter"
username
-----------------------------10265533117308
content-disposition: form-data; name="Uploaded file"; filename="abc.xls"
[... contents ...]
-----------------------------10265533117308
-- content end -----
and in your case, the excel binary fo abc.xls is only the part
of [... contents ..]
usually people use some kind of framework or libray such as struts
not to take care of handling plain data sent by browser.
i hope this helps you.
regards
ichy
