Hellos balachandra ! :D
I create this solution and it works fine:
Cliente side:
final FormPanel form = new FormPanel();
final FileUpload upload = new FileUpload();
public static String UPLOAD_RESULT = "";
public static String EVENT_NAME = "";
private boolean isIMG = true;
public FileUploadPadroes(){
form.setEncoding(FormPanel.ENCODING_MULTIPART);
form.setMethod(FormPanel.METHOD_POST);
HorizontalPanel holder = new HorizontalPanel();
upload.setName("upload");
holder.add(upload);
upload.addChangeHandler(new ChangeHandler() {
@Override
public void onChange(ChangeEvent event) {
form.setAction("/padroes/UploadService?isIMG="+isIMG()+"&eventName="+
EVENT_NAME);
if(upload.getFilename()==null || upload.getFilename().length()<1){
// PageBusAdapter.publishDoCreateEventUpload("No valid file attached.");
}else{
form.submit();
}
}
});
form.add(holder);
}
public FormPanel getForm() {
return form;
}
public FileUpload getUpload() {
return upload;
}
public boolean isIMG() {
return isIMG;
}
public void setIMG(boolean isIMG) {
this.isIMG = isIMG;
}
On server side :
protected void doPost(HttpServletRequest request, HttpServletResponse
response) throws ServletException, IOException {
// ServletFileUpload uploadHandler = new ServletFileUpload();
boolean isIMG = Boolean.parseBoolean(request.getParameter("isIMG"));
// Create a factory for disk-based file items
DiskFileItemFactory factory = new DiskFileItemFactory();
// Create a new file upload handler
ServletFileUpload upload = new ServletFileUpload(factory);
if(isIMG){
// Set factory constraints
factory.setSizeThreshold(1000000);//"resources/upload"
// Set overall request size constraint
upload.setSizeMax(1000000);
}else {
// Set factory constraints
factory.setSizeThreshold(10000000);//"resources/upload"
// Set overall request size constraint
upload.setSizeMax(10000000);
}
try {
/*
* Parse the request
*/
String eventName = request.getParameter("eventName");
List<FileItem> lUploadingFiles = upload.parseRequest(request);
for (FileItem item : lUploadingFiles) {
processUpload(item,isIMG,eventName);
}
}catch(FileUploadException ex) {
FileUploadPadroes.UPLOAD_RESULT = "The file size is to big," +
" must be less than 1MB.";
log("Error encountered while parsing the request",ex);
} catch(Exception ex) {
log("Error encountered while uploading file",ex);
}
}
private void processUpload(FileItem uploadItem,boolean isIMG,String
eventName)
{
File uploadedFile = null;
String uploadFileName = uploadItem.getName();
if(isIMG)
uploadedFile = new File("padroes/resources/event/"+ eventName +"/images/" +
uploadFileName);
else
uploadedFile = new File("padroes/resources/event/"+ eventName +"/videos/" +
uploadFileName);
/**
* handling file uploads
*/
try
{
uploadItem.write(uploadedFile);
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
