HTML form posting with input type="file"

Hi,
I am trying to create a servlet to accept POST requests sent from a form which has an input field of type="file".
When I first tried I found that I was only recieving the filename of the file and not getting any contents.. I then found out that I needed enctype="multipart/form-data" in my html form tag.
Now my servlet isn't picking up any of the form data plus the reader returned by HttpServletRequest.getReader() just throws an IOException whenever I use it..
I have tried to google for how to get this working but I haven't found much. Any help would be appreciated.

Thanks cool..
I also found this after some late night googling..

I'm trying to not use one of these utility classes for now until I find out exactly how they get their data from the HttpServletRequest object..

Try get value in input type="file". Not is full path. It's bug?

In html:
<input type="file" id="path_image">
In javascript:
path_image = document.getElementById("path_image").value;
Example:
Select path: "/images/image.gif"
This result:
path_image = " image.gif"

You cannot preset input values for input type="file" elements. It's prohibited by HTML specification. It's namely a security hole.
Imagine that one developed a webpage with input type="file" pointing to c:/passwords.txt and added window.onload=form.submit(), what would happen if one opened such a webpage?
That said, get rid of scriptlets and step over to taglibs/EL. This is 2009, not 1999.

Problems with clearing files from input type="file"

I'm using &lsaquo;input type="file".. to upload files in some javascript.
The page containing the &lsaquo;input type="file".. is not reloaded, so data on the &lsaquo;input type="file".. is not cleared.
I've done this with form.reset() in IE, which cleares files from &lsaquo;input type="file".., but this doesn't work in Firefox. The next time I try to submit a file two files are submitted.
I've even tried to replace the &lsaquo;input type="file".. to clear all data, but if i replace it with a &lsaquo;input type="file".. with same id, the files is still there from before.
So my question is, how do I clear files selected

The firmware/file system on the iPhone is locked unless you jailbreak your iPhone. The sync function via a USB cable and iTunes is the only way to add or retreive data unless your phone is jailbroken (and that is limited to music, movies, contacts, pictures, etc)
There are applications in App Store which will create a file storage system on your iPhone and allow your PC to access those folders/files via WiFi network (iFiles is one, there are others)
iBluetooth requires your phone to be jailbroken.
You can use a bluetooth connection from iPhone to PC to play music only thru the PC speakers without having a jailbroken phone.
If all you want to do is transfer pictures, iTunes will do that. It is already set up, just plug in the phone, and go to the photos tab and choose which picture app on the PC to transfer the photos into. Then everytime you sync your phone, it pulls the new pictures off the camera roll.

How to get full path using HTP.PRINT(' "input type ="file") ....

Hello everybody,
I am working on uploading file from page to another one using HTP package, but whenever I submit the form, it only takes the filename without the full path.
for example :
if i sent 'c:\dir\a.txt' , the other page receives file parameter as 'a.txt'
the code is here
PROCEDURE upload(appno in varchar2,wsct in varchar2) AS
l_real_name VARCHAR2(1000);
BEGIN
HTP.htmlopen;
HTP.headopen;
HTP.title('Test Upload');
HTP.headclose;
HTP.bodyopen;
HTP.header(1, 'Test Upload');
HTP.print('<form action="https://ssltrng.uaeu.ac.ae/trng/document_api.upload1" method="get">');
HTP.print(' File to upload: <input type="file" name="file" >
HTP.print(' <input type="submit" value="Upload">');
HTP.print('</form>');
HTP.bodyclose;
HTP.htmlclose;
END upload;
the other page see it as
file is 'Water lilies.jpg'
Thanks

Do not understand the problem.
The code you've posted is a PL/SQL web enabled procedure that produces a dynamic HTML page. This page contains a form. And a full URL reference to the CGI that will process the form's data.
This is unusual - as it seems to be that the form is submitted across domains and web servers.. You usually refer to a local CGI procedure to deal with a form - no need for a fully qualified URL that includes web server and domain name.
If the CGI procedure that receives the form is also a PL/SQL web enabled procedure, that the uploaded file will be placed in the documents table (as defined in the DAD alias) by mod_plsql, prior to the web enabled procedure being called. The documents table will contain the Mime type, file name, file contents and other details.

input type="file" directory?

Hi,
I was hoping that someone could tell me if there is a way to have <input type="file"> point or default to a specific server directory rather then have the user choose the directory? If not, is there a work around?
Thanks

2 issues (attempt #2... I accidentally closed my browser and lost this whole big reply, which I will attempt to recreate now... )
1) What is the point? The file input is meant to select files for upload from the client to the server. Using this field in a POST form will cause the browser to take the file and upload the entire file to the server. (Not sure about GET forms, but probably it would do nothing.)
In this case, it's a moot point. If the file's on the server, the input/form's work is done, so to speak.
File input fields are not general filename selection dialogs like JFileChooser. There's nothing in HTML (and it's an HTML issue, really, not a JSP issue) that let's you do something like that... which leads directly to....
2) There's no way to do this with a regular server because while most can show directory listings,...
a) most have it disabled, rightly, for security reasons
b) if enabled, users only get an HTML page which clicking on files downloads the file and there's no way to turn this type of thing to your web app's advantage.
So if you need to let users select the file on the server (just the filename), you'll have to build some HTML page set to do this. This means having a servlet or something get a list of files to show to the user in the browser as HTML. The user can click folders to navigate into them, or select a file or files, however you want to do it. Then submitting that back to the server would give you the filename.
You could implement this in a Javascript popup window to make it look like a file chooser, of course. But it's still special HTML pages/forms and server side handling. But you have to build this, or find some 3rd party servlet or something that will do it for you. (which gives me an idea for something to do this weekend, maybe :-)

Can't get parameter in struts when using input type="file"...?

Hi everyone:
Can the common html tag and struts tag be used together?I have an example:in jsp
<html:form method="post" action="sendmail.do" enctype="multipart/form-data">
<tr><td>MailTo:</td><td>
<html:text property="mailto"/></td></tr>
<tr><td>MailFrom:</td><td>
<html:text property="mailfrom"/></td></tr>
<tr><td>Subject:</td><td>
<html:text property="title"/></td></tr>
<tr><td>Content:</td><td>
<html:textarea property="content" rows="7" cols="30"/></td></tr><tr><td>
Attach:</td><td>
<input type="file" name="myfile"/></td></tr><tr><td>
<html:submit/><html:reset/>
</td></tr>
</html:form>
In Action,I want to use the code "request.getParameter("myfile")" to get the file real path.But I always get "null".Why "request.getParamter("myfile")" is null although I choose a file in jsp?
Can struts Tag and html Tag be use together?Thks

Instead of the Request, you need to use MultiPart request in this case.
This is because of the following statement you are using in the form tag. {enctype="multipart/form-data"}
Hope it helps....

How would I do a http post with a xml file

How would I do a http post with a xml file.
I have a url called https://localhost:8443/wss/WSS and the XML file is sent as part of the HTTP POST body.
How would I send this XML file when posting?

most people just add feedback to the comments they've asked about already, rather than ignoring all the feedback and making a new post with the exact same information:
http://forum.java.sun.com/thread.jspa?threadID=5247331&messageID=10020973#10020973
If you want to add in an XML file to a POST command, you'd add it just like any other file you'd attach to a post request, especially (if you're request is the same as your last post) if you're just doing a jsp page. I'd do it something like this:
<form method=POST ENCTYPE="multipart/form-data" action="https://rcpdm.mnb.gd-ais.com/Windchill/servlet/IE/tasks/DJK/fcsAddContentComplete.xml">
<H3> File Name </H3>
<input type=file name=filename>
<input type=submit value="Do it!">
</form>Then again, this solution has literally nothing to do with java, and you still need to make sure that your servlet knows what to actually do with that information you're sending it.

Uploading a file using input type=file

Hi,
I'm not sure if I'm in the right place or not. If not can you please let me know where to find and answer for my question.
I'm trying to upload a file in oracle self-service (online page) and I found that the input type=file will let me select the file so I place the input type inside my htp.formopen command.
I used the following when opening the formopen
htp.formOpen(my_link, 'post',null, 'multipart/form-data');
then I created the <input type="file"> tag
But when I send the link to my second page to see if the input type works I get the page not found error.
I'm thinking that maybe is because my 2nd page doesnt have a parameter that will hold the file but right now I'm not sure how to declare the file variables.
Do you have any idea what could be wrong?
Thanks

What does your form do when you submit it? Handling file uploads is a bit of a convoluted process. I'd recommend starting here for some guidance:

Use of input type="file"

Hellow
How can I use the HTML tag <input type="file" > in jsp/servlets ?
how can I got the file and saving it?

Take a look at this page: http://search.java.sun.com/search/java/?qt=jsp+upload&x=39&y=6 - it is a search page and you can use it to find whether or not anyone has asked the question you have before. Often you will find that the question you have asked has been asked before, sometimes as much as 29000 times. It is quicker than asking a question for the first time because you don't have to wait for replies. - they are already there. I also believe that if you don't know understand search engines you are unlikely to understand Java.
To help with your search you may want to know that the "file" input type creates a Multipart request and that the term "com.oreilly.servlets" may well be relevant too.

[SOLED] Firefox input type = file selects the wrong file

When I have use a webpage in firefox that has an upload feature, Firefox often selects the wrong file. I can reproduce this problem by simply creating a form with an input tag like this:
<input type="file" />
When I enter the file selection screen and open fileA the input box contains fileA, fileB or fileC. It seems kind of random to me. I use KDE 4.5 btw, if that matters.

It seems to be some kind of kde problem. When I delete ~/.kde4/share/config/* it works fine. I tried deleting the all files in share/config starting with a-m and it still didn't work. Then I deleted every file from n-z and it didn't work so it's probably a combination of files that give these problems. I don't feel like setting up KDE all over again so damn, it's back to Icewm, again...

Input type=file

dear all,
          anybody know how to transfer the the value from <input type="file"> when it
          posted to it self (like as modify form).
          sample:
          self.jsp
          <form action="self.jsp">
          <input type="file" name="files"
          value="<%=request.getParameter("files")%>">
          <input type=submit name="go">
          </form>


          First your form enctype must be "multipart/form-data" ..
          Second there should be a service (java class or something) running on the server
          that can read the servlet input stream and upload.
          My Question ..Could you ever display value in file object's text field ?? I couldn't!
