안녕하세요.
java라는 놈을 2주전에 처음 접해본 학생입니다.
지금 하고 있는 작업은 디바이스에서 image를 서버로 보내면, 서버에서 프로세싱 해주고 단어들을 디바이스로 돌려주는 시스템을 짜고 있습니다. 이미지 전송은 웹에서 검색을 통해 HTTP POST방법을 이용하려고 합니다.
웹을 어슬렁 거려서 아래와 같은 소스를 구해서 구현을 했는데요..

이유는 모르겠는데. 서버에 접속하고 파일생성을 할 때, 에뮬레이터에서 파일을 열 때 source not found가 뜨면서 안되네요;;
잘 알지못해서 질문도 제대로 못하는 저의 상황을 너그러이 이해해 주시길 바라며, 답변 부탁드릴게요. ㅠㅠ 아래에는 웹에서 구한 소스입니다. 소스 출처는 "http://getablogger.blogspot.com/2008/01/android-how-to-post-file-to-php-server.html"입니다.
가르침좀 주세요 .. 

서버의 php코드
< ?php

$target_path = "uploads/";

$target_path = $target_path . basename( $_FILES['uploadedfile']['name']);

if(move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $target_path)) {
echo "The file ". basename( $_FILES['uploadedfile']['name']).
" has been uploaded";
} else{
echo "There was an error uploading the file, please try again!";
}

int ch;

StringBuffer b =new StringBuffer();
while( ( ch = is.read() ) != -1 ){
b.append( (char)ch );
}
String s=b.toString(); 
Log.i("Response",s);
dos.close();


}
catch (MalformedURLException ex)
{
Log.e(Tag, "error: " + ex.getMessage(), ex);
}

catch (IOException ioe)
{
Log.e(Tag, "error: " + ioe.getMessage(), ioe);
}
}

}

Many of the headers included in the above file is not required, i was trying and failing :).

Now to upload file here is the java code from my activity class


public void uploadFile(){


try {
FileInputStream fis =this.openFileInput(NAME_OF_FILE);
HttpFileUploader htfu = new HttpFileUploader("http://11.0.6.23/test2.php","noparamshere", NAME_OF_FILE);
htfu.doStart(fis);
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
