Hi,

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


Here is Client code



Server Code


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.


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


But I still wonder what is the problem with the client code I posted earlier?

you may modify the client code posted earlier like this:
postMethod.setRequestHeader("Content-type", "multipart/form-data;boundary=---------------------------sdjkahdj294919323195");

or you can annotate the line:method.addRequestHeader("Content-type", "multipart/form-data" );//multipart-mixed
