Subject Re: Uploading a File using apache commons Http clien
Date Tue, 18 Sep 2007 04:56:29 GMT


Hi James,
 
 Thanx for your help.
 I have removed  following code....
   client.getParams().setParameter("http.useragent", "My Browser");
>                 postMethod.addParameter("test","testvalue");
>                 NameValuePair[] nm = {new NameValuePair("test","test")};
>                 postMethod.setRequestBody(nm);


But still it's not working.

I have not tried simple java client,Please send me some link for that.

Thanx
Rajesh
