Hellow folks,
i'm trying to upload a image to a web server. I'm using j2me from the client side and Grails on the server side. The code bellow is related to the j2me:

Code:
...
DataOutputStream out = null;

public void run() {
 String boundary = Long.toString(System.currentTimeMillis(), 16);
 HttpConnection http = (HttpConnection) Connector.open(url);

 http.setRequestMethod(HttpConnection.POST);
 http.setRequestProperty("MIME-version", "1.0");
 http.setRequestProperty("Content-Type", "multipart/form-data;  boundary=" + boundary);
 http.setRequestProperty("Accept", "application/octet-stream" );
 http.setRequestProperty("User-Agent", "Profile/MIDP-2.0 Configuration/CLDC-1.0");

 out = new DataOutputStream(http.openOutputStream());

 //WRITE DATA
 this.writeField("description", "Image description");
 this.writeField("type", "Image");
 this.writeFile("media", "image/jpeg", "image.jpg", aByte);
 this.close();

}


public void writeField(String name, String value) {
 out.write("--".getBytes());
 out.write(boundary.getBytes());
 out.write("\r\n".getBytes());
 // write content header
 out.write(("Content-Disposition: form-data; name=\"" + name + "\"").getBytes());
 out.write("\r\n".getBytes());
 out.write("\r\n".getBytes());
 // write content
 out.write(value.getBytes());
 out.write("\r\n".getBytes());
}

public void writeField(String name, String mimeType, String fileName, byte[] data) {
 out.write("--".getBytes());
 out.write(boundary.getBytes());
 out.write("\r\n".getBytes());

 out.write(("Content-Disposition: form-data; name=\"" + name + "\"; filename=\"" + fileName + "\"").getBytes());
 out.write("\r\n".getBytes());
 
 if(mimeType != null) {
   out.write(("Content-Type: " + mimeType).getBytes());
   out.write("\r\n".getBytes());
 }

 out.write(data, 0, data.length);
 out.write("\r\n".getBytes());

}

public void close() throws java.io.IOException {
 // write final boundary
 out.write("--".getBytes());
 out.write(boundary.getBytes());
 out.write("--".getBytes());
 out.write("\r\n".getBytes());

 out.flush();
 out.close();
}
However, all data "description", "type" and the byte array ("media" field) are null when the server tries to read.

Do someone know why?!!!

Thanks in advance!!!
