Visual Studio download a document from a document libary and upload it to a jaxrs webservice in java

Question

I have created a custom ribbon action and a application page in visual studio. The user
presses my ribbon in sharepoint and it calls the application page that in turn downloads that file. here is the code:
namespace Save_to_PLM.Layouts.Save_to_PLM
public partial class ApplicationPage : LayoutsPageBase
protected void Page_Load(object sender, EventArgs e)
if (Request.QueryString["file"] != null)
DownloadDocument(Request.QueryString["file"].ToString());
private void DownloadDocument(string fileName)
SPSecurity.RunWithElevatedPrivileges(delegate()
using (SPSite oSiteCollection = new SPSite(SPContext.Current.Site.Url))
using (SPWeb mi_web = oSiteCollection.OpenWeb())
string path = System.Web.HttpContext.Current.Server.MapPath(fileName);
string name = System.IO.Path.GetFileName(path);
Console.WriteLine(name);
Microsoft.SharePoint.SPFile spFile = mi_web.GetFile(fileName);
Response.ClearHeaders();
Response.ClearContent();
Response.ContentType = "application/force-download";
Response.AppendHeader("content-disposition", "attachment; filename=" + name);
Response.BinaryWrite(spFile.OpenBinary());
Response.End();
But i want to http post that file to my jaxrs webservice in java. How do  i do that
programmatically? I am very new .net i usually code in java.

Hi,
Here is a blog about how to call a Java EE Web Service from a .Net Client for your reference:

If you want to download a document from a Sharepoint library, we can use the REST API provided by SharePoint and use Apache HttpComponents in Java.

About how to upload file using jaxrs webservice in C# code, I suggest you post it to C# or ASP.Net Forum, you will get more help and confirmed answers from there.
