Cannot genetrate java client for file upload webservice - web-services

Question

I have a simple file upload web service as a small part of my project.
This is what I have done so far on the server side :
#POST
#Path("/file")
#Consumes(MediaType.MULTIPART_FORM_DATA)
public Response uploadFile(List<Attachment> attachments,#Context HttpServletRequest request) {
System.out.println("Got an attachment!");
for(Attachment attr : attachments) {
DataHandler handler = attr.getDataHandler();
try {
InputStream stream = handler.getInputStream();
MultivaluedMap map = attr.getHeaders();
OutputStream out = new FileOutputStream(new File("/home/yashdosi/s/" + getFileName(map))); //getFileName is a seperate private function..
int read = 0;
byte[] bytes = new byte[1024];
while ((read = stream.read(bytes)) != -1) {
out.write(bytes, 0, read);
}
stream.close();
out.flush();
out.close();
} catch(Exception e) {
e.printStackTrace();
}
}
return Response.ok("file uploaded").build();
}
It works perfectly well when requests come from html forms...when I try to send a request from a java client it simply doesnt work..!!
Any ideas about on creating a java client for this code..
Here is the code I tried with...maybe there is a simple error in this code but..I dont see it...also as I said this code simple wont work...no errors or anything else....when I tried printing something on the server console to see if the service is invoked...it did NOT print anything..so I think I am unable to contact the service for some reason...
public static void uploadPhoto()
{
String url = "http://localhost:8080/fileupload-ws/services/postdata";
String output = null;
PostMethod mPost = new PostMethod(url);
HttpClient client = new HttpClient();
try
{
File imageFile = new File("/home/yashdosi/1.jpg");
BufferedImage image = ImageIO.read(imageFile);
ByteArrayOutputStream baos = new ByteArrayOutputStream();
ImageIO.write(image, "jpg", baos);
byte[] encodedImage = Base64.encodeBase64(baos.toByteArray());
String data = " " + " " + "" + "image/jpeg" + " " + "" + new String(encodedImage) + " " + "";
mPost.setRequestBody(data);
mPost.setRequestHeader("Content-Type", "text/xml");
client.executeMethod( mPost );
output = mPost.getResponseBodyAsString( );
mPost.releaseConnection( );
} catch (HttpException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
System.out.println(output);
}

Finally got a client working!!
HttpClient httpclient = new DefaultHttpClient();
try {
HttpPost httppost = new HttpPost("http://localhost:8080/fileupload-ws/services/postdata");
FileBody img = new FileBody(new File("/home/yashdosi/1.jpg"));
FileBody html = new FileBody(new File("/home/yashdosi/hotmail.html"));
MultipartEntity reqEntity = new MultipartEntity();
reqEntity.addPart("image", img);
reqEntity.addPart("html", html);
httppost.setEntity(reqEntity);
httppost.setHeader("Content-Type", "multipart/form-data");
System.out.println("executing request " + httppost.getRequestLine());
HttpResponse response = httpclient.execute(httppost);
HttpEntity resEntity = response.getEntity();
System.out.println("----------------------------------------");
System.out.println(response.getStatusLine());
if (resEntity != null) {
System.out.println("Response content length: " + resEntity.getContentLength());
}
EntityUtils.consume(resEntity);
}
catch(Exception e)
{
e.printStackTrace();
}
finally {
try { httpclient.getConnectionManager().shutdown(); } catch (Exception ignore) {}
}
