I get 404 error. Simply the file is not written in HDD. Like I said,
when i run the app in hosted mode, this works.
Here is the servlet code:
package com.myapplication.server;
import java.io.BufferedInputStream;
import java.io.BufferedOutputStream;

public class FileUploadServlet extends HttpServlet {
private static final long MAX_SIZE = 1024 * 1024 * 1024 * 4;
private static final String CONTENT_TYPE_UNACCEPTABLE = "{error:
'File upload failed. "
+ " EXE file can't be uploaded'}" + MAX_SIZE + " bytes or
less'}";
private static final String KEY_WORD = "FILENAME";
private static final String DATA = "FILEDATA";
@Override
public void doPost(HttpServletRequest request, HttpServletResponse
response)
throws ServletException, IOException {

try {
items = upload.parseRequest(request);
} catch (Exception e) {
e.printStackTrace();
}
Iterator it = items.iterator();
String tmp = "";
FileItem data = null;
while (it.hasNext()) {
FileItem item = (FileItem) it.next();
if (item.getFieldName().equalsIgnoreCase(KEY_WORD)) {
tmp = new String(item.get());
} else if (item.getFieldName().equalsIgnoreCase(DATA)) {
data = item;
}
}
json = processFile(data, tmp);
response.setContentType("text/plain");
response.getWriter().write(json);
}
/**

*/
private String processFile(FileItem item, String fileName) {
if (!isContentTypeAcceptable(item)) {
return CONTENT_TYPE_UNACCEPTABLE;
}
try {
File fl = new File("/tmp/" + fileName + MyServiceImpl.getLogin
());
fl.deleteOnExit();
fl.createNewFile();
BufferedInputStream b = new BufferedInputStream(item
.getInputStream());
int i = -1;
BufferedOutputStream out = new BufferedOutputStream(
new FileOutputStream(fl));
while ((i = b.read()) != -1) {

}

} catch (FileNotFoundException e) {

e.printStackTrace();
}
return "good";
}
/**

private boolean isSizeAcceptable(FileItem item) {
return item.getSize() <= MAX_SIZE;
}
/**

* @return
*/
private boolean isContentTypeAcceptable(FileItem item) {
return true;// !item.getContentType().equalsIgnoreCase
(ACCEPTABLE_CONTENT_TYPE);
}
}
