H:form enctype="multipart/form-data" gets removed
I tried to create a file upload page using tomahawk 1.1.6, JSF RI 1.2_05-b06-FCS and facelets.
What I found is that the h:form removes the enctype="multipart/form-data" when rendering the JSF page.
In the resulting html page the enctype is entirely missing.
As a result the fileupload doesn't work, since the browser doesn't even send the file.
I read that JSF doesn't support multipart messages, but with this behaviour it prevents other libs like tomahawk accomplishing this task. Does anyone know whether there a way to solve this issue other then patching the FormRenderer?
regards,
Artur

when i restore my backup from computer why do my minutes texts and data gets removed from my pay as you go sim card?
As long as it's unlocked it will work with any SIM, incl. EE SIMs.
If you buy abroad you need to ensure it is compatible with UK mobile frequencies, on which I cannot advise. -
Why does my form data gets cleared out when clicking on the back button.
Can someone explain why does my form selections get cleared out when clicking on the back button.
I have a JSP page that displays a form with some selections and text boxes. I populate the page and submit the request. The action on the submit call another jsp page, which processes the data and displays the results via a <jsp:include> statement which calls the results page. When clicking on the back button from the results page, it returns me to the form page, but the selections are cleared out.
1. Is there something in my calling of the pages that causes this behavior and can I prevent it?
I notice that the behavior is different when using the IE 6.0 version Netscape 7.1. IE clears the page Netscape 7.1 retains the settings.
If I cannot prevent this behavior does that mean I will have to save the state of the form data. And if I have to save the form data, what would be the easiest method of doing this. I'm a beginner to JSP and Java, but have some ASP experience. I don't understand why the back button in a JSP request clears the form data but a regular HTML page does not can someone explain?
THANKS.the browser doesn't have to remember what you submitted and fill that back in.
you can't prevent it unless you can ensure a new request to the server in which you can fill the default values in there. -
Am trying to see what happens when user fills in adobe form and clicks submit. What will be sent back to server? Filled PDF or XML? If its XML, does it get stored on the user's machine in some temporary files?? If not, atleast where does it get stored on the server?
Am basically trying to develop a functionality where user clicks submit and all the form data gets stored in an XML file on the local machine. Any inputs?Hi Narayana,
You can use Web Dynpro Java with embedded Interactive PDF forms; and within your WDJ application, you can call various 'models': web services, EJBs and BAPIs/RFCs etc.
So to pass data to an SAP system, you don't automatically need the XML data as a BAPI is sufficient. Check out <a href="https://www.sdn.sap.comhttp://www.sdn.sap.comhttp://www.sdn.sap.com/irj/sdn/developerareas/webdynpro?rid=/library/uuid/49f2ea90-0201-0010-ce8e-de18b94aee2d#backend">these SDN tutorials</a> to do this.

Hi, I am using HP11 and iPlanet web server. When trying to upload files over HTTP using FORM ENCTYPE="multipart/form-data" that are bigger than a few Kilobytes i get a 408 error. (client timeout). It is as if the server has decided that the client has timed out during the file upload. The default setting is 30 seconds for AcceptTimeout in the magnus.conf file. This should be ample to get the file across, even increasing this to 2 minutes just produces the same error after 2 minutes. Any help appreciated. Apologies if this is not the correct forum for this, I couldn't see one for iPlanet and Web, many thanks, Kieran.
Hi,
You didnt mention which version of IWS. follow these steps.
(1)Goto Web Server Administration Server, select the server you want to manage.
(2)Select Preference >> Perfomance Tuning.
(3)set HTTP Persistent Connection Timeout to your choice (eg 180 sec for three minutes)
(4) Apply changes and restart the server.
*Setting the timeout to a lower value, however, may prevent the transfer of large files as timeout does not refer to the time that the connection has been idle. For example, if you are using a 2400 baud modem, and the request timeout is set to 180 seconds, then the maximum file size that can be transferred before the connection is closed is 432000 bits (2400 multiplied by 180)

Having garbage characters while using enctype="multipart/form-data"
Hi to all! =)
I'm uploading a CSV file in JSP ny adding [enctype="multipart/form-data"].

I have declared a UTF-8 charset above my JSP

Problem with ENCTYPE='multipart/form-data'
In my program I want to upload a file along with other details.
I've dowloaded org.apache.commons.fileupload.* jar files and everything works fine only if I give
<INPUT TYPE='file' NAME='file1'>
i.e the file is uploaded
But if I add any other field it becomes blank
Title : <INPUT id=text1 maxlength="30" name=GHN1 >
the value of GHN1 becomes blank. what cud be the problem.
Here is my program

Problem with transfering unicode form data in MULTIPART/FORM-DATA
HI experts,
I have this web based multilingual application. Page 1(form6.jsp) is basic registeration form with 5 fields and one image upload to the server. Page 2(verify.jsp) is another jsp page for verification of UTF data entered in page 1.
page 2 (verify.jsp) also uses a bean called (verify.java) for picking up values. page 3(insertEntry.jsp) is the page for inserting that data into the Database and uses a bean called (logicbean.java).
Now, the problem im facing here is that if i use multipart/form-data, the unicode text filled in page1 is shown as garbage when its is transfered to page2 and displayed on page2. It is all gibberish. But if i do not use multipart/form-data, the unicode text transfered from page1 to page2 is displayed perfectly on page2.Im using devenagari(UTF) language for filling in details.

Multipart/form-data and file attachment
Hi ,
This question has probably been asked before, but if not then here it is. Any replies will be appreciated:
Q. When using "Enctype=Multipart/form-data", with file attachment alongwith other form fields, is it mandatory to attach a file ? What if user selects no file to attach?
Q. If no, then how can it be possible that a form can be submitted without attaching a file since when I try to submit a form with no file attached to it, it gives me error message saying :java.lang.NullPointerException
Q. Does it mean that I can't have a form with a blank "File" input field, if the form's Enctype is "multipart/form-data"? Since users may not select a file to attach to the form, in other words it is an optional.
I hope I was clear enough in explaining my questions.
Thanks in advance.I am using Orielly's file attachement pacakge.
Here's what I am doing in my JSP page: It does the following:
int maxFileSize = 10 * 1024 * 1024; // 5MB max
String uploadDir = "/direct/files/upload/";
String FormResults = "";
String FileResults = "";
String fileName = "";
String fileName2 = "";
String paramName="";
String paramValue="";
File f;
int filecounter=1;
first get the form fields using following code:
MultipartRequest multi = new MultipartRequest(request, uploadDir, maxFileSize);
Enumeration params = multi.getParameterNames();
//Get the form information
while (params.hasMoreElements())
paramName = (String) params.nextElement();
paramValue = multi.getParameter(paramName);
if (paramName.equals("emailconfirm"))
emailconfirmation = paramValue;
else if (paramName.equals("Requester"))
Requester = paramValue;
else if (paramName.equals("TodaysDate"))
TodaysDate = paramValue;
else if (paramName.equals("Extension"))
}//end while
Then it gets the file information using the following code: I have two file fields in my form so that's why I am using a filecounter to find out if user has attached two files or just one:
Enumeration files = multi.getFileNames();
while (files.hasMoreElements())
String formName = (String) files.nextElement();
if (filecounter == 2)
fileName2 = multi.getFilesystemName(formName);
String fileType = multi.getContentType(formName);
f = multi.getFile(formName);
FileResults += "<BR>" + formName + "=" + fileName2 + ": Type= " + fileType + ":
Size= " + f.length();
else
{ fileName = multi.getFilesystemName(formName);
String fileType = multi.getContentType(formName);
f = multi.getFile(formName);
FileResults += "<BR>" + formName + "=" + fileName + ": Type= " + fileType + ":
Size= " + f.length();
filecounter=filecounter+1;
Then after composing the mail message I send email with the form fields and file attachments using following code:
Properties props = new Properties();
MimeBodyPart mbp1 = new MimeBodyPart();
MimeBodyPart mbp2 = new MimeBodyPart();
MimeBodyPart mbp3 = new MimeBodyPart();
URLDecoder urlDecoder = new URLDecoder();
String to1 = urlDecoder.decode(toemail);
String from1 = urlDecoder.decode(fromemail);
String cc1 = urlDecoder.decode(ccemail);
props.put( "mail.host", host );
Session session1 = Session.getDefaultInstance(props, null);
// Construct the message
Message msg = new MimeMessage( session1 );
msg.setFrom( new InternetAddress( from1 ) );
msg.setRecipients( Message.RecipientType.TO, InternetAddress.parse( to1, false ) );
msg.setRecipients( Message.RecipientType.CC, InternetAddress.parse( cc1, false ) );
msg.setSubject( subject );
msg.setHeader( "X-Mailer", "ExceptionErrorMail" );
msg.setSentDate( new Date() );
mbp1.setText(mail_message);
mbp1.setContent(mail_message, "text/html");
// Send the email message
FileDataSource fds = new FileDataSource(uploadDir + fileName);
FileDataSource fds2 = new FileDataSource(uploadDir + fileName2);
mbp2.setDataHandler(new DataHandler(fds));
mbp3.setDataHandler(new DataHandler(fds2));
mbp2.setFileName(fileName);
mbp3.setFileName(fileName2);
Multipart mp = new MimeMultipart();
mp.addBodyPart(mbp1);
mp.addBodyPart(mbp2);
mp.addBodyPart(mbp3);
msg.setContent(mp);
Transport.send( msg );
//email sent...
//delete the two files from the server..
File f2 =new File(uploadDir + fileName);
f2.delete();
File f3 =new File(uploadDir + fileName2);
f3.delete();
//End of code
So when I don't attach a file and submit my form , I get the error message that I mentioned in my previous post.
Any more ideas? -
This pop up has been occurring about once a minute when I am on certain sites.
This web page is being redirected to a new location. Would you like to resend the form data you have typed to the new location?
How do I get it to stop?-> Tap ALT key or press F10 to show the Menu Bar
-> go to Help Menu -> select "Restart with Add-ons Disabled"
Firefox will close then it will open up with just basic Firefox. Now do this:
-> Update ALL your Firefox Plug-ins https://www.mozilla.com/en-US/plugincheck/
-> go to View Menu -> Toolbars -> unselect All Unwanted toolbars
-> go Tools Menu -> Clear Recent History ->'' Time range to clear: '''select EVERYTHING''''' -> click Details (small arrow) button -> place Checkmarks on '''Cookies & Cache''' -> click "Clear Now"
-> go to Tools Menu -> Options -> Content -> place Checkmarks on:

what is multipart/form-data ?
generally A form have some input fields and a submit button ? but what is
multipart/form-data ? or is it same thing ?http://www.w3.org/TR/REC-html40/interact/forms.html
enctype = content-type
This attribute specifies the content type used to submit the form to the server (when the value of method is "post"). The default value for this attribute is "application/x-www-form-urlencoded". The value "multipart/form-data" should be used in combination with the INPUT element, type="file". -
"xfa.data.nodes.remove" wreaking havoc on dynamic forms
I have a web service that I created using Workbench, and it is using the Query Multiple Rows as XML component. It returns multiple items depending on criteria supplied by the form filler. The data is being placed into a drop down field. In order to facilitate this I followed what I had read previously in these forums, which is to load the xml into the DOM and then navigate to the nodes needed and loop through and add then into the drop down. That works great. The problem happens when I want to reset the data in the drop down in order to facilitate another query. So what happens in the form is:
A user is presented with a drop down that has two options, to 'add new object', or to 'edit existing object'.
If the user selects 'add new object', a blank form is displayed and the user can fill it out. Once the form is filled out, a web service takes the information and creates a row in the database.
If the user selects 'edit existing object' a web service fires and brings back xml data and places the data into two separate drop downs, one for 'staff lead' and one for 'departments'. When they select an option, another web service fires to query the database based on the selection. It works fine the first time. But say someone decides to change an option from either the 'staff lead' or the 'departments' drop downs, which would logically change the criteria for the query, things get crazy. I have to use the xfa.data.nodes.remove command in order to remove the nodes from the DOM so that the next query comes in and loads into the DOM correctly. If I don't do this, then the drop down keeps the previous data in it.
The problem is that once you use the command on a Dynamic form (this is important, the form must be dynamic.) things start disappearing on the form. Can't figure out why. Help...
Very important: The form needs to be a dynamic form. The problem does not happen on static forms.
MikeI have looked at the result set and everything looks good to me. I have my root node and all of the form data elements under it, then I have the staff lead, and department node. Each have a child node named repeating, (I've tried different names there and it didn't make a difference.) and inside the repeating node are the values. In my remove statement I point to the either department or staff lead nodes (depending on which I need to clear.) and go through the xfa.data.nodes.remove step. What's interesting is that somehow this command is changing the visibility of subforms, which are not listed anywhere in the data DOM? I'm more confused now.

Upload a file to the server - multipart/form-data ?
I need to upload a file from my local machine to the server from a jsp page. I was asked to use a form with ENCTYPE = "multipart/form-data". but I am not sure how it works. Can any one enlighten me on the process or is there any other way to do it.
nullYou can find the jsp source & the java sources which exactly does that in the iFS CMS sample code section. Go to Products -> Internet File system -> sample code -> Content Management System. This application allows the user to upload files from a local file system into iFS. This application creates the file in the iFS repository. You may want to save it in the file system of the web server. You may have to make little changes but the functionality is exactly what you are looking for.
Hope this helps.

Multiple select multipart/form-data + FileUploader
Hi
I'm using asp multiple select form field with
multipart/form-data +
FileUploader to upload a file (works fine) and writing the
contents of
a form to a database which works fine apart from the multiple
select
which although allows me to select multiple items only
returns the
first selected item to the database.
Anywork arounds to this??
Thanks in advance!!

There's nothing more dangerous than a resourceful idiotMulti-part requests are not packaged the same as regular requests, so the getParameter() method doesn't work on it (although I think it would get anything passed through the query string as part of the action parameter but I'm not sure).
You can also try the com.oreilly.servlet class MultipartRequest. I don't know if that's the same one found in the www.servlets.com link, but it is REALLY easy. Essentially, it looks like this:
MultipartRequest mr = new MultipartRequest(request, "[pathtosavefiles]'");
String param = mr.getParameter("paramname");
So instead of calling getParameter() on the request object, you now instead call it on the MultipartRequest object. When you instantiate the MultipartRequest object, it parses the request body for you, and also saves any uploaded files into the directory you specified in your path in the constructor.
I hope that helps.

Multipart/form-data using HTTPService, sending a binary file and some text in the same request.
Hi There,
I am new to FLEX and also new to writing a client for a web service.
My question is more about flex (Flash builder 4.5) APIs, what APIs to use.
I want to access a web service, that's published here.
https://build.phonegap.com/docs/write_api
here is the description of webservice
===========
1) I have to do a post on POST https://build.phonegap.com/api/v1/apps
2) content type has to be "multipart/form-data"
3) JSON bodies of requests are expected to have the name 'data'
data will be someting like this
'data={"title":"API V1 App","package":"com.alunny.apiv1","version":"0.1.0","create_method":"file"}'
4) include a zip file in the multipart body of your post, with the parameter name 'file'.
===========
I want to make a 'multipart/form-data' Post and send
one string and one zip file.
My first question to self was If i send both string + binary data in the body ...
how will server understand where string end and where zip file starts?
Then read on W3.org( http://www.w3.org/TR/html401/interact/forms.html#h-17.13.4.2 )
How is text + binary data can be sent through "multipart/form-data" post requst.
there has to be some boundries.
After this I read and example in flex and tried following it.
http://codeio.wordpress.com/2010/04/03/5-minutes-on-adobe-flex-mimic-file-upload-for-in-me mory-contents/
but it doesn't seems to be working for me.

content += 'Content-Disposition: form-data; name="file";' + fileData + "nr";
content += "—————————–" + boundary + "–nr";
service.request = content;
service.send();In the past I have used URLVariables with URLRequest and URLLoader to achieve this kind of requirement.
Check out http://livedocs.adobe.com/flex/3/html/help.html?content=17_Networking_and_communications_3 .html which should be useful. My preference has always been to use this style instead of HTTPService objects, giving you a little more control which is what you need here.
Let me know if you need any more assistance.
