Servlets :: Uploading And Downloading Files Using JSP
Aug 18, 2014I would like to know what is the best way to upload & download files using Servlets/Jsp's . In some websites I have seen example using third party API(by oreilly). Is it better to follow any third party or can we do it just by using I/O streams. What are the steps of uploading files. And where do we need to store files once the user uploads ,Database or server??

View Replies View RelatedJSF :: Styling PrimeFaces File Upload Tag
Mar 22, 2014I'm having some problems styling the PrimeFaces upload tag <p:fileUpload /> in my application.
In my xhtml code I have the following:
<p:fileUpload id="fileUpload" fileUploadListener="#{filters.upload}"
allowTypes="#{filters.uploadTypes}" invalidFileMessage="#{filters.uploadBadType}"
sizeLimit="#{filters.uploadSize}" invalidSizeMessag="#{filters.uploadBadSize}"
update="fileUpload fileTable filterTab uploadMessage hiddenNum hiddenPhoto uploadError footer
namePhotSystem checkOverwrite"
description="Select Text File" disabled="#{filters.fileuploadDisabled}" fileLimit="1"
fileLimitMessage="You are only allowed to upload one file at a time"
styleClass="fileUploadClass" label="Choose the File to Upload" auto="true" />
This all works correctly, both the AJAX update and on the server, but I'm unable to get the button or buttons displayed in the way I need.
By including the following in my CSS:
.ui-fileupload.fileUploadClass {width:428px;}
.ui-icon-plusthick {display:none;}
.ui-button-text {width:200px; height:20px;}
the first sets the width of the button bar, and by looking at the HTML code generated by PrimeFaces, I discovered that the second hides the "+" to the left of the "Choose" button, which here has been replaced by the text "Choose the File to Upload". However, this text is displayed on two lines, with the word "Upload" on the second. I want the whole text to be on one line, but no matter what I do, I cannot get this to work properly. The third line of my CSS code does indeed reduce the height of the button, but the width does not work at all, and the last part of the text is simply lost. How do I put all the text on one line and adjust the width of the button?
Another question is that when I remove the auto="true" attribute from the tag, which I had originally, the "Upload" button is displayed to the right of the "Choose" button, and when a file is chosen but not yet uploaded, it is displayed below the button. This is a capability that I might still want, however, I am unable to style the display, and in particular the progress window to the right of the file name and size. All the files I want to upload are relatively small text files, and I want to adjust this window or even hide it completely. How is this done?
Incidentally, because the files are all quite small, I have disabled the display of the "Cancel" button, so either only the "Choose" button is shown, or the "Choose" and "upload" buttons.

Correct Way To Upload Large Data File
Nov 25, 2013Our client has a user facing web application running on Jboss. There is a separate admin application (in its own ear) but deployed on same Jboss server on which user facing web application is running.
They need a screen to upload large amount of data into database. Their original files were in excel with size > 60 mb. We suggested following to them:
a. Change upload format to CSV - this brought down file sizes to 25-30 mb
b. Upload process will be MDB - asynchronous processing of data so that admin web app does not stop responding
We also suggested following to them:
a. Host admin app on a different machine so that user facing site does not respond slow during data processing
b. We can provide incremental upload feature and they should upload files in the chunks of 4-5 mb, specifically if they have user a web page to upload such files - they don't buy this argument though.
c. Data processing can be a separate script instead of a part of admin web application. They can FTP files to a designated location and this script will process those files.
I have following questions:
Q1 - Have you seen upload of such large datafiles to a web application? I see sites like Zoho CRM or Salesforce do not support such data imports and mostly fail or not respond.
Q2 - Is there a set of guidelines/best practices to upload large data files of this nature? How do insurance companies or others with enormous set of data accomplish such tasks (what is the architecture of such programs)?
JSP :: Drag And Drop Images (single Or Multiple) To Upload

JSF :: File Upload And Prevent Refresh Calling Page

JSF :: Execution Of File Upload Primefaces Multiple With Counter
Apr 16, 2015I am not all secure on the execution of the fileupload Primefaces.
The uploading execution occurs normally, but I would like to have a counter that control's the received files. The problem is that sending files go by so fast by this method that appears to be running in parallel. My question is whether this behavior is normal while sending files.
If it is not, where may be the error. If it is normal what can i do to make the counter really take the right value?
I'm using the scope of the "bean" type of view, but when im trying to run the session the problem also occurs depending on the file size.
If my files are very small, the execution is very fast and I cant follow the counter. If I clean the code the execution usually occurs no matter the size of the files.
@ManagedBean (Name = "bean")
@ViewScoped
public class BeanUpload {
private int counter;
@PostConstruct
public void init () {
counter = 0;
[Code] .....
The result on the console for 3 files is:
COUNTER EX: 1
COUNTER EX: 1
COUNTER EX: 1
If I run the code in debug mode on the console this is the result:
COUNTER EX: 1
COUNTER EX: 2
COUNTER EX: 3

Servlets :: How To Upload File To Google Drive With Java Web Application
Dec 4, 2014How to upload file to google drive using java. my java code is.
HttpTransport httpTransport = new NetHttpTransport();
JsonFactory jsonFactory = new JacksonFactory();

httpTransport, jsonFactory, CLIENT_ID, CLIENT_SECRET, Arrays.asList(DriveScopes.DRIVE))

GWT 2.4 - File Upload Servlet To Accept CSV And Parse For Insert Into Database
Oct 22, 2014Creating a file upload servlet to accept a CSV and parse for insert into a database, however, whenever I click submit, it always seems to open a new tab/window. Below is the method I have that builds the upload form: (Using GWT 2.4)
private void buildUpload(){
LayoutContainer headerContainer = new LayoutContainer(new ColumnLayout());
headerContainer.setStyleAttribute("padding", "5px");
add(headerContainer);
NamedFrame hiddenFrame = new NamedFrame("uploadFrame");
final FormPanel form = new FormPanel(hiddenFrame);

Is there something I'm missing? or something I've added that makes it open a new tab/window?
Servlets :: JPEG Image Upload - Data Input Stream
Jan 25, 2014Iam trying to upload jpeg image.
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
[Code] ....
In servlet the below code
DataInputStream din = new DataInputStream(request.getInputStream());
byte[] data = new byte[0];
byte[] buffer = new byte[50];
int bytesRead;
while ((bytesRead = din.read(buffer)) > 0 ) {
byte[] nData = new byte[data.length + bytesRead];
System.arraycopy(data, 0, nData, 0, data.length);
System.arraycopy(buffer, 0, nData, data.length, bytesRead);
data = newData;
}
What i see is servletinput stream does't have any values.It does't even enter while loop.

View Replies View RelatedServlets :: Large File Upload From Client To Content Management System
Sep 3, 2009I have a requirement where a large file (100 -200MB) is uploaded from the client to a content management system. I am using a servlet with Apache Commons File Upload API. Apache FileUpload has 2 ways of handling files,
1) Non-Streaming
2) Streaming
Currently I use the Non-Streaming approach where the servlet stores the file in a temp location and upload the same into the content management system - This is taking lot of time so I am trying to implement Streaming API.
Content Management API supports streaming in 2 methods,
a) SetContent - Takes the file's ByteArrayOutputStream as input -> This gives OutOfMemoryException because the file being large
b) AppendContent - Takes the file's ByteArrayOutputStream as input -> This method can be called multiple times to upload the large file but I dont know how to do this. The Apache File Upload gives InputStream of the file and I need to split that into chuncks and append into the content management system.
How to convert InputStream to 4KB ByteArrayOutputStream so that I can use the AppendContent method in content management API?
