I was getting a similar error message because I didn't specify the name attribute on my fields. Possibly adding a name to the submit button might also fix this issue.

Thank you for your settings. Your advice - this is a godsend.

I am posting multiple files through http post method from .Net application to Java Servelet Page and I am getting the Error:
N~java.io.IOException: Corrupt form data: no leading boundary: != ------------------------------8d08693613639c3

Can any body please & please help me out:
my code is :

public int postenrollments(string source, string posturl)
{

string[] enrolldirect;
int FindDirectoriesLength=System.IO.Directory.GetDirectories(source).Length ;
string SuccessUploadedFiles = ConfigurationManager.AppSettings.Get("UploadedEnrollmentsSource");
if (FindDirectoriesLength == 0)
{
status = 0;
}
else
{
enrolldirect = Directory.GetDirectories(source).ToArray();
HttpWebRequest webreq = (HttpWebRequest)WebRequest.Create(posturl);

NameValueCollection nvc = new NameValueCollection();
nvc.Add("stTerminal", "000018112");
nvc.Add("stAgentID", "13220001");
nvc.Add("stvendorId", "112");

posturl += "?stTerminal=" + "000018112" + "&stAgentID=" + 13220001 + "&stvendorId=" + 112;
foreach (string dir in enrolldirect)
{
if (VerifyFiles(dir))
{
string[] enrollfiles = Directory.GetFiles(dir).ToArray();
UploadFile[] files = new UploadFile[enrollfiles.Length];
string[] filestoUpload = new string[enrollfiles.Length]; //This For PostMultipleFiles & UploadFilesToRemoteUrl Method
for (int i = 0; i < enrollfiles.Length; i++)
{
filestoUpload[i] = enrollfiles[i];//This For PostMultipleFiles & UploadFilesToRemoteUrl Method
files[i] = new UploadFile(enrollfiles[i]);

}
HttpWebRequest req = (HttpWebRequest)WebRequest.Create(posturl);



HttpWebResponse resp = UploadFilesToRemoteUrl(posturl, filestoUpload, "", nvc);




StreamReader respreader = new StreamReader(resp.GetResponseStream());
string response = respreader.ReadToEnd();

if (response.Trim() != "N~Invalid Terminal Id")
{
status = 1;
logmgr.Log("Directory :" + dir + "is uploaded");
if (!Directory.Exists(SuccessUploadedFiles))
{
Directory.CreateDirectory(SuccessUploadedFiles);///Main Directory Creation
}

}
else
{
status = 2;
logmgr.Log("Problem while Directory :" + dir + " upload");
}

}
else
{
logmgr.Log("Directory :" + dir + "is missing few files");
status = 3;
}
}
}
return status;
}
