Hello,

URLConnection conn = url.openConnection();     
            conn.setDoOutput(true);     
            OutputStreamWriter wr =     
                new OutputStreamWriter(conn.getOutputStream());     
            wr.write(data);

Basically , we have to upload a Excel document to an External Client , we used to do that using Excel directly by logging into their website and uploading the excel file,
Now we want to automate this, by using XML . but still have the Excel attachment
The guide says, I can post the following documents to an URL using MIME, I am not sure what they mean by that.
"The following example shows a Catalog Upload document. It contains two documents enclosed in a MIME
envelope: a CatalogUploadRequest document and a CIF 3.0 catalog."

--kdflkajfdksadjfklasdjfkljdfdsfdkf--Now my question is , even if I use Apache or any other thing, how can I actually send 2 files, ( one which is header and one Excel file or cif file what ever it is)I suggest you look at the HTTP MIME sectiona t http://www.w3.org/TR/html4/interact/forms.html#h-17.13.4.2 and after that look at http://hc.apache.org/httpcomponents-client-ga/httpmime/examples/org/apache/http/examples/entity/mime/ClientMultipartFormPost.java for an e.g. You can also add multiple attachments, just google for it. Now that i think about it, it probably might be possible to do it with native JDK components, but not 100% sure of it.
