no boundary was found ！

I am trying to send some parameters and a file to the server using Commons HTTPClient (V 3.1). On the server end I am using Commons fileupload( V 1.1.1.1) to get parameters and file. I am getting following exception

Do any one have idea what could be the problem and possible resolution?

Thanks for sharing. I found following code in FileUploadBase class which is throwing error.
view plaincopy to clipboardprint?
    
            int boundaryIndex = contentType.indexOf("boundary=");  
            if (boundaryIndex < 0)  
            {  
                throw new FileUploadException(  
                        "the request was rejected because " 
                        + "no multipart boundary was found");  
            }  
  
 
            int boundaryIndex = contentType.indexOf("boundary=");
            if (boundaryIndex < 0)
            {
                throw new FileUploadException(
                        "the request was rejected because "
                        + "no multipart boundary was found");
            }
 

Now I wonder what is problem with code where I set content type as multipart/form-data or multipart/mixed?

On the other hand if I submit same data with html form having enc-type="multipart/form-data" it's work fine.

I think form-data is the correct type to use here, since you're really submitting a form.

Here I modified client code, used deprecated method and it worked. Below is the code

            method.addParameter("username","imerys");  
            method.addParameter("password","a311xhq23");  
            method.addParameter("RefNo", "05355/1001388462");  
            method.addParameter("payload",strXML);  
            File f = new File("C:/development/test.pdf");  
            method.addParameter("pdfdoc",f.getName(),f);  
            File f = new File("C:/development/test.pdf");    
                
            HttpClient client = new HttpClient();    
            int statusCode = client.executeMethod(method);

            String responseString = method.getResponseBodyAsString();    
            System.out.println("Response : \n\n"+responseString);
