UIX Upload File
Hi
I've tried to upload a file using UIX Servlet.
I had used code from UIX Developer Guild and it's success .
Now I want to know How to check whether the file name being upload from user already exits in the target folder on my server. And I also want to know how to alert user via javascript's popup , I means how to use javascript and UIX in combination
Could you please give me some idea ?
Thanks
Attila -
Assuming you are using uiXML - check out the "Multipart requests" section in the JavaDoc for the oracle.cabo.servlet.AbstractPageBroker. The gist of it is that you'll want to create an extension of UIXPageBroker which overrides doUploadFile() and uses the MultipartFormItem API to get at the contents of the uploaded file.
If you are using UIX JSP, you can use the oracle.cabo.share.util.MutlipartFormHandler to explicitly process your multipart requests.
And of course, you'll want to include a fileUpload component in your UIX document - and be sure to set the "usesUpload" attribute of your UIX form to true.

I'm sure you have in your application lib directory to jars which aren't compatible to each other.
And the problem occured between my myfaces and tomahawk jars .
See this page:
http://wiki.apache.org/myfaces/CompatibilityMatrix
It tells you which myfaces and tomahawk jars you can use together.
Hope it can help.

Adobe Muse won't publish (Error uploading file)
After making simple animations using Adobe Edge Animate it seems as though none of the assets will publish with my site after importing them into Muse.
In Edge animate I saved for "web animation" and published. Then I went to muse and hit "place". I went to preview and everything works fine. When I go to publish there are always errors in uploading my assets with '.png' extensions.
Any help is much appreciated. I have completely scrapped my website and created another, reinstalled Animate and have renamed all my files, I'm not sure whats wrong here.
I got one animation working, and that can be seen here under the Photography section, but I have multiples that will be shown on my page at one time.
http://chasebodydesign.businesscatalyst.comI get the error uploading file everytime I try publishing the animation.

Change upload file name with com.oreilly.servlet.MultipartRequest to handle the file upload
1. when use com.oreilly.servlet.MultipartRequest to handle the file upload, can I change the upload file name .
2. how com.oreilly.servlet.MultipartReques handle file upload? do it change to byte ?
what different? if I use the following method?
File uploadedFile = (File) mp.getFile("filename");
FileOutputStream fos = new FileOutputStream(filename);
byte[] uploadedFileBuf = new byte[(int) uploadedFile.length()];
fos.write(data);
fos.close();My questions are
1) when use oreilly package to do file upload , it looks like i line of code is enough to store the upload file in the
file direction.
MultipartRequest multi =
new MultipartRequest(request, dirName, 10*1024*1024); // 10MB
why some example still use FileOutputStream?
outs = new FileOutputStream(UPLOADDIR+fileName);
filePart.writeTo(outs);
outs.flush();
outs.close();
2) can I rename the file name when I use oreilly package? -
Request.getParameter() when uploading files
Hi, I need to upload files and do other works .. such that, in my html ..
<form name="composer" method="post" ENCTYPE="multipart/form-data">
<input type=hidden name="a" value="a">
<input type=File name=inputfile>
<inpu type=button name=Upload onClick='upload file'>
<inpu type=button name=otherStuff onClick='do other stuff'>
</form>
In the jsp for 'do other stuff', I have the following statement to get the value of a
String a = request.getParameter("a");
However, it returns 'null', if I erase the 'ENCTYPE' part from the html file, it works. How can I get it right?If your ENCTYPE is multi-part/form-data, then there is another technichque to read the form parameters.
request.getParameter() won't work.
first u need to read the requenct explicitely and divide the contents into parameters, files etc. and then read the parameter values.
you can get a lot of stuff regarding this on web, like 'uploading files using jsp'.
have fun!! -
Remove link for uploaded files in application
Hi all,
I've been following the tutorial on how to upload and download files in application at http://download-uk.oracle.com/docs/cd/B32472_01/doc/appdev.300/b32469/up_dn_files.htm. I have now created my own table which stores the uploaded files and can download them successfully. I would now like to add the ability to delete these files within the application and was wondering what the best way of doing this was?
I would like to add another column to the displayed report with a 'Remove file' link for each listed file, which when clicked would delete the file from the table. I've already tried using a similar method to the one used to upload the files (instead of uploading the file, the called procedure deletes it from the table using the specified ID), but this causes the application to display a blank page when the link is clicked, which I dont want (but does delete the file).
I would appreciate any suggestions.
Regards,
DaveDave,
See the login page:
http://htmldb.oracle.com/pls/otn/f?p=31517:101
There are details on how to access the application builder, where you can see how the
setup of that download, delete, upload application has been done.

Delete an uploaded file (in custom table) from a report
Hi,
I have a report of uploaded files (the files are saved in my own table, not in APEX_APPLICATION_FILES) - I'd like to add a delete link to each file in my report so that the user can delete a particular file.
How do I go about doing this?
Thanks.Melissa,
It is now working. You missed couple of things:
1. javascript in the header
2. you were pointing to the page 1 and your process was on the page 2
3. you passed the value to a non existing item on the page 3
4. the request which would fire the delete process was triggered by a wrong request

How to upload file from client to server
Can someone please help.
User needs to browse file on his desktop and upload file using browse button. This file should then be uploaded to the server. I am using javascript in the front end and servlet in the back.
Any help will be highly appreciated.
Thanks,
IndrasishJakarta Commons FileUpload is the standard way of doing the file uploading these days. You can find source, binaries and documentation at the Jakarta Site http://jakarta.apache.org/ . The Commons has a number of subprojects, so start with the Commons libraries, then find FileUpload.

Is there a way to silently upload files?
Ok, so I've taken the plunge. I've started working on an AIR
app using Flash CS3. I'm putting together a little app that will
keep my online store updated with all the product updates from our
wholesaler. This includes parsing a csv file, downloading product
images from the wholesaler, updating the database, and then
uploading the images to our server.
The problem is that AIR does not seem to have the
functionality to silently upload files! Sure, I can use the
file.reference object to fire off the browse method, which then
opens the OS file browser window BUT I would really like the whole
thing to be hands off. In the past, I've written these types of
apps using Visual Studio but I haven't touched VS in two years.
Has anyone run across a way to silently upload or ftp files
in AIR?Hey Oliver,
Thanks for your answer--the fact that it CAN be done has
gotten me a lot further on finding a solution. Here's what I have
so far. As it runs, I can see the progress and completion of the
upload but I'm still not getting it saved. I'm uploading it to a
ColdFusion processing page.
AS3 Code:
import flash.filesystem.*;
import flash.net.URLRequest;
//Silent File Upload (no browse window)
function imageUpload(imageName,uploadPage):void
trace('Starting Upload of ' + imageName + '\n');
var myFile:File =
File.applicationDirectory.resolvePath(imageName);
var request:URLRequest = new URLRequest(uploadPage);
request.method = URLRequestMethod.POST;
myFile.addEventListener(ProgressEvent.PROGRESS,progressHandler);
myFile.addEventListener(Event.COMPLETE,completeHandler);
myFile.upload(request,"theFile");
function progressHandler(event:ProgressEvent):void {
var file:FileReference = FileReference(event.target);
var pLoaded =
Math.ceil(event.bytesLoaded/event.bytesTotal*100);
trace(pLoaded + '% uploaded');
function completeHandler(event:Event):void
trace ('Upload complete.');
var uploadPage = "
http://www.aaronbday.com/upload_file.cfm";
imageUpload("angelic_cat.jpg",uploadPage);
Here's the CFM page:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0

<!---we only want images--->

destination="#ExpandPath("test/")#"
filefield="theFile"
nameconflict="overwrite"
accept="image/jpg,image/jpeg,image/gif,image/pjpeg"

enctype="multipart/form-data">

Any ideas? Thanks! -
