how 2 supress contentType when using multipartentity
Please help me.
I building a bot and trying to upload file along with form fields. when
compare the request generated by httpclient with that of microsoft browser,
I notice that httpclient is having following format after the header.
---boundaryid
Content-Disposition: form-data; name=fieldname1
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
value1
---boundaryid
Content-Disposition: form-data; name=fieldname2
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
value2
---boundaryid
:
:
But internet explorer generates request in following format
---boundaryid
Content-Disposition: form-data; name=fieldname1
value1
---boundaryid
Content-Disposition: form-data; name=fieldname2
value2
---boundaryid
:
:
Notice the Content-Type and Content-Transfer-Encoding fields are populated
by HttpClient.
The webserver is not expecting these two fields and therefore throwing me an
error as it is not able to trace the value for the required formfield (I
guess it is poorly written server)
How do I get rid of these extra two values while using httpclient
multipartentity. please see snippet of my code below
Part[] parts = new Part[files.length + nvPairs.length];
//setup form fields
for(int i = 0 ; i nvPairs.length ; i++){
parts[i] = new StringPart(nvPairs[i].getName(),
nvPairs[i].getValue(),CHAR_SET);
}
//setup files
for(int i = nvPairs.length, j=0 ; j files.length ; j++,i++){
File targetFile = new File(files[j].getValue());
parts[i] = new FilePart(files[j].getValue(), targetFile);
}
post.setRequestEntity(new MultipartRequestEntity(parts, post.getParams()));
httpClient.getHttpConnectionManager().getParams().setConnectionTimeout(5000);
statusCode = httpClient.executeMethod(post);
Please help ASAP.
Thanks in advance.

Send/Receive serialized object using Apache's httpclient package
Hi,
Is it possible send/receive serialized object using HttpClient? I always
get java.io.StreamCorruptedException: invalid stream header Exception.
Here is my server side (servlet code)
public void doPost (
HttpServletRequest request,
HttpServletResponse response)
throws ServletException, IOException
{
response.setContentType(application/x-www-form-urlencoded);
ObjectOutputStream oos = new
ObjectOutputStream(response.getOutputStream());
ArrayList l = new ArrayList();
l.add(Index Server is running);
oos.writeObject(l);
}
Client side code that access this servlet
public OutputStream sendRequest (String method, HashMap args)
throws IOException, IndexServerCommunicationException
{
PostMethod post = new PostMethod(m_url);
try
{
post.setRequestEntity(new
StringRequestEntity(something));
m_client.executeMethod(post);
ObjectInputStream ois = new
ObjectInputStream(post.getResponseBodyAsStream());
return ois;
}
finally
{
post.releaseConnection();
}
}
Any help is appreciated.
Thanks

Hi .. I followed your steps . I have downloaded the certificate and stored as DER in local.
