Not a multipart form upload
I created a jsp that uses my extended version of editcurrentrecord (which creates an html form to insert a new record) and a rowsetbrowser.
I am able to insert new records when running the jsp in jdev 3.1 but when I deploy it to ias and try to insert a record I get the error: not a multipart form upload
Please help.
Thanks
I upgraded to JDev 3.2 and rewrote my code to extend the new
version of EditCurrentRecord. Now when I deploy to 9ias I get a new error:
Error Message: java.lang.NullPointerException: I'm following the online help
to deploy but I must be missing something cause it works in JDev. Any
suggestions?

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.

I have narrowed down the problem to the point where i understand that the "request.getParameter()" function for multipart is not able to understand or read UTF data properly. The out.println prints garbage from this function on the console. im using WAS
plz help
thanx in advance

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)

Useful Code of the Day: Multipart Form File Upload
So, you want to upload files to your web server, do ya? Well, I've seen this topic posted a few times in the last month or so and many of the response I've seen here haven't included definitive answers. Of course, the actual problems vary, but ultimately, a bunch of people want to do file upload from an applet or application to an existing file upload script (CGI, PHP, JSP, etc.) on a web server. And invariably, there are problems with formatting the HTTP request to get things working.
Well, I had a need to do the same thing. I realize there are other solutions out there, such as some sample code that comes with Jakarta Commons Upload. But since we all like reusable code, and we also all seem to like reinventing wheels, here's my go at it: MultiPartFormOutputStream!
MultiPartFormOutputStream is a specialized OutputStream-like class. You create your URLConnection to the server (a static method included can do this for a URL for you, as some of the settings, doInput and doOutput specifically, seem to confuse people). Then get the OutputStream from it and create a boundary string (a static method to create one is provided as well) and pass them to the constructor. Now you have a MultiPartFormOutputStream which you can use to write form fields like text fields, checkboxes, etc., as well as write file data (from Files, InputStreams or raw bytes).
There are some convenience methods for writing primative type values as well as strings, but any higher level objects (aside from Files or InputStreams) aren't supported. (You can always serialize and pass the raw bytes.)
Sample usage code is below. Also, any recommendations for improvement are requested. The code was tested with the Jakarta Struts.
import java.io.*;

The code was tested and worked for the author. If anyone else has some useful code, feel free to post it under this heading.I have a weird problem here. I'm using the Java POST (slightly altered for my purposes) mechanism but the receiving script doesn't receive any form variables (neither files nor regular form fields). If I try using the same receiving script with a regular upload form, it works. Because I've been pulling my hair out, I even went so far as to analyze the ip-packets. I can see that the file is actually sent through the Java POST mecahnism. Anybody any ideas. Here's the ip-packet of the failing upload:
----- Hypertext Transfer Protocol -----

One detail worth mentioning is that I don't read a file from harddisk, I'm streaming it directly to the connection outputstream from an image compression utility. But I can see the data in the ip-packets, and even if that somehow didn't work right, it doesn't explaing the fact that the receiving scripts reports no form fields whatsoever.

Multipart form (file upload) processing in providers
Hello,
Just want to find out if anyone has successfully implemented a file upload mechanism within a Portal channel.
According to the Provider API (http://docs.sun.com/source/816-6428-10/com/sun/portal/providers/Provider.html), the wrapped request/response objects do not support several methods that are essential to process file uploads, namely "getContentLength" and "getInputStream". I am currently trying to use the Apache commons-fileupload utility which uses those methods to process file uploads. This is also the case for another popular file upload utility from servlets.com.
Does anyone have any info/explanation regarding this limitation in Portal Server 6, and any workarounds to this issue. One workaround is to have a window popup that interacts directly with an external webapp.
Any ideas/suggestions will be appreciated, thanks in advance.
jeffHi Jeff,
The Sun ONE Portal Server DesktopServlet does not have the ability to process a request with the content encoding type of multipart/form-data. DesktopServlet does not pass the input stream for the request on to the Provider.
To accomplish handling of multipart/form-data type requests, it is necessary to create a companion servlet or JSP that process the multipart/form-data. This servlet can then pass control back to the Portal channel. The data from the file can be shared between the servlet and the provider by using static Java members or by storing the data in a back-end database and then passing a reference to the data over to the provider.

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.

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? -
Can't pass parameter from HTML form of multipart/form-dta type to JSP
I am using request.getParameter(passed variable name) to pass data from HTML form to JSP with no problem. WHen I try to pass data from HTML form of multipart/form-dta type to JSP as following:
< form enctype="multipart/form-data" name="theForm" method="post" ACTION="http://titan.ssd.loral.com:7778/ifs/jsp-bin/ifs-cts/stringsecond.jsp">
The passed value is null. Why?
How can I pass data successfully from this form to JSP?
How can I pass data from JavaScript to JSP?
Thank youI am using request.getParameter(passed variable name)
to pass data from HTML form to JSP with no problem.
WHen I try to pass data from HTML form of
multipart/form-dta type to JSP as following:
< form enctype="multipart/form-data" name="theForm"
method="post"
ACTION="http://titan.ssd.loral.com:7778/ifs/jsp-bin/if
-cts/stringsecond.jsp">
The passed value is null. Why?because the jsp most likely does not handling of POST parameters like this.
How can I pass data successfully from this form to
JSP?jsp's are not meant to read such amounts of data. this (= uploading) is a typical task for a specialized servlet. there you have full control over input and output. if you need to, you can still forward to a jsp after processing in the servlet.
How can I pass data from JavaScript to JSP???? i'm not sure what exactly you mean. normally you put it into an url and submit it.

Close connectionI also faced the same problem. To make this code work you will have to include the image.jpg in the jar. To do that, copy the image file in the src directory inside your project folder (if you are using netbeans) and then build the project.
Remember, the web server should be running in background. -
Problem with session while sending a multipart-form (a file via post)
I have a problem with the communication between my applet and my server. I use a method to post an xml to my server with the Content-Type "application/x-www-form-urlencoded" and with it I'm not having any problem to preserve the session.
However I use another method I found in the forums to post files and try to adapt it, but I'm being send from the server to the login page because it's not recognizing my session
Can anybody help me? This is my method
public String uploadFile(String adr, BufferedImage img) {
String res = "";
String CONTENT_BOUNDARY = "--abvx98734732";
String s;
File f = null;
URL url;
URLConnection conn;
try {
url = new URL(adr);
conn = url.openConnection();
conn.setDoOutput(true);
conn.setRequestProperty("Content-Type",
"multipart/form-data; boundary=" + CONTENT_BOUNDARY);
conn.setRequestProperty("file-Name", "process_image.jpg");
DataOutputStream wr = new DataOutputStream(conn.getOutputStream());
wr
.write(("--"
+ CONTENT_BOUNDARY
+ "\r\n"
+ "Content-Disposition: form-data; name=\"fileData\"; filename=\""
+ "process_image.jpg" + "\"\r\nContent-Type: image/jpg\r\n\r\n")
.getBytes());
ImageIO.write(img, "jpg", wr);
wr.write(("\r\n--" + CONTENT_BOUNDARY + "--\r\n").getBytes());
wr.flush();
BufferedReader in = new BufferedReader(new InputStreamReader(conn
.getInputStream()));
while ((s = in.readLine()) != null) {
res += s;
in.close();
catch (MalformedURLException muo) {
muo.printStackTrace();
catch (IOException io) {
io.printStackTrace();
return res;
}This is how I preserve session in my other method:
private static final String SESSION_KEY = "_session_id";
URLEncoder.encode(SESSION_KEY, "UTF-8") + "=" +
URLEncoder.encode(sessionId, "UTF-8");
wr.writeBytes(content);
....Yes, the only way is to pass the value u want in the query string. But make sure that the value is not too large.
In case you have too much info i guess the only way is to circumvent multipart and handle the process in your own custom class, which wont be worth the effort if u need pass only 2-3 small parameters.
Always,

Hi,
Before I upload a file, I want to get a few parameter
values (getParameter) on the form first. I've tried
using com.oreilly.servlet MultipartRequest and a few
other free servlets but they require that the file
must to be uploaded first. For example:
MultipartRequest multi = new
MultipartRequest(request,filepath, 10*1024*1024);
//this will instantiate the object and upload the
file
String command = multi.getParameter("command"); //get
the form parameter
Is there any way I can get the parameter first before
uploading the file? I truly appreciate any helps you
can provide me.
Regards,
Lily -
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.

Get all the values from a multiple select in a multipart form
Hi there!
I am using a form with enctype="multipart/form-data" in order to upload files from the form.
I have read this page: http://commons.apache.org/fileupload/using.html and everything works well for my form.
The only problem is that I can't get all the values from a "multiple select" html object. I get only one value.
Using servlets I have used this method:
public java.lang.String[] getParameterValues(java.lang.String name) But now I have enctype="multipart/form-data" in my form and I can't use this way...
Is there a way to get all the values of a multi-valued parameter?
Thanks a lot!
StefanoHi
I have got solution for this problem so, I am listing here logic
assume tag name of html
<select name="moption" multiple="multiple">
iterate it in as
String moption="";
boolean cnt=true;
while(itr.hasNext())
FileItem fi=(FileItem)itr.next();
if(fi.isFormField())
if(fi.getFieldName().equals("moption"))
if(cnt==true)
moption=fi.getString();
cnt=false;
else
moption=moption+","+fi.getString();
If wants more help then mail me your problem
at [email protected]
Thanks!

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.
public function createNewApp(cb:Function , appFile : File):void
var service:HTTPService = new HTTPService();
service.url = ROOT+"apps";
service.showBusyCursor = true;
service.addEventListener(ResultEvent.RESULT, function(e:ResultEvent):void {
//translate JSON
trace(e.result);
var result:String = e.result.toString();
var data:Object = JSON.parse(result);
cb(data.link);
service.addEventListener(FaultEvent.FAULT, defaultFaultHandler); //todo : allow user to add his own as well
authAndUploadNewApp(service,appFile);
private function authAndUploadNewApp(service:HTTPService,appFile : File):void {
var encoder:Base64Encoder = new Base64Encoder();
encoder.encode(username + ":"+password);
service.headers = {Accept:"application/json", Authorization:"Basic " + encoder.toString()};
service.method ="POST";
var boundary:String = UIDUtil.createUID();
service.contentType = "multipart/form-data; boundary=—————————" + boundary;
var stream:FileStream = new FileStream();
stream.open(appFile, FileMode.READ);
var binaryData:ByteArray = new ByteArray();
var fileData : String = new String();
stream.readBytes(binaryData);
stream.close();
fileData = binaryData.readUTFBytes(binaryData.bytesAvailable); // I think this is where I have problem.... how do
//how do i converrt this bytearray/stream of data to string and send it in my post request's body - i guess if this step work rest should work..
var params: String = new String();
var content:String = "—————————" + boundary + "nr";
content += 'Content-Disposition: form-data; name="data";' + '{"title":"ELS test app 2","package":"com.elsapp.captivate","version":"12.3.09","create_method":"file"}' + "nr";
content += "—————————" + boundary + "nr";
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.
