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"].
<html:form method="POST" action="/upload.do" enctype="multipart/form-data">Now, I have a problem on handling Japanese Characters. (becomes garbage)
I have declared a UTF-8 charset above my JSP
[<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="Shift_JIS" %>]Using
System.out.println(response.getCharacterEncoding());in my action, I get "ISO-8859-1" instead of UTF-8
I don't have any clue why this has happened. Can someone teach me how to override the "ISO-8859-1" coding.
Any suggestions will be deeply appreciated.

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).

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)

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

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?

Artur

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?

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.
// form6.jsp

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

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.
null

You 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.

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.

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

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.

                              var service:HTTPService = new HTTPService();
                              service.url = ROOT+"apps";

                              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.

ALSB 2.5 - routing request containing multipart/form-data

Hello,
I'm having difficulty routing a request (multipart/data-form with 2 MIME sections) in a
business service.
First, I set up the "attachments" variables in a stage:
<ctx:attachments>
<ctx:attachment>
<ctx:Content-Disposition>form-data; name="RI"; filename="RI"</ctx:Content-Disposition>
<ctx:Content-Type>text/plain</ctx:Content-Type>
<ctx:Content-ID>1146702408781_1</ctx:Content-ID>
<ctx:body>
<RI/>
</ctx:body>
</ctx:attachment>
<ctx:attachment>
<ctx:Content-Disposition>form-data; name="CI"; filename="CI"</ctx:Content-Disposition>
<ctx:Content-Type>text/plain</ctx:Content-Type>
<ctx:Content-ID>1146702408781_1</ctx:Content-ID>
<ctx:body>
<CI/>
</ctx:body>
</ctx:attachment>
</ctx:attachments>
then do node replacements of <RI/> and <CI/> in each
<ctx:body> section.
Then in the routing node,
"Set Transport Headers" for "Outbound Request"
[x] Pass all Headers through Pipeline
Add Header
[Content-Type] --> [Set Header to "multipart/form-data"]
Then I used Ethereal (network protocol analyzer) to
observe the raw packets that business service sent
the request to the target service. It looked like
the POST httprequest output by ALSB does not conform to
the other posting programs that I have wrote in Python
and Ruby. The target webservice rejects the request
sent by ALSB, but accepts those sent by the Python/Ruby
programs.
Anyone here have any experience in how to set this up?
Thanks
Charles

Hello,
Make sure you construct the attachment variable properly as specified in the documentation:

What is multipart/form-data ?

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".

Extension type for mime-type "multipart/form-data"

          Hello:
          If I want to register a mime-type of type "multipart/form-data" in WebLogic 6.0
          what, if any, extension should I specify fot it in the web.xml? Is it necessary
          to specify this mime-type for handling "multipart/form-data" type http requests?
          Thanks
          John


You cannot use request.getParameter() for Multipart/form-data.
          You need to Use getInputStream and use the InputStream to read data.
          Please Refer Jeason Hunters Implementation for the same. Its a very good example.

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 idiot

Multi-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.

Leading garbage characters when using CipherInputStream

So, after receiving an encrypted message, I can decrypt it perfectly except that I get a random amount of leading garbabe characters. Using the same plaintext, here are examples of the beginning of the output file for two runs (using od -c to look at the files):
0000000 315 7 004 371 242 \0 w ` t h e L L S E
and
0000000 1 " 246 317 0 j 321 V t h e L L S E
The part beginning with "The LLSE..." is correct.
The fact that the leading garbage appears to be random leads me to believe that there is something wrong with the crypto rather with the file I/O.
Here's the relevant code chunk:
Cipher sharedCypher = Cipher.getInstance("DES/CFB8/PKCS5Padding");
SecretKeySpec DESKeySpec = new SecretKeySpec(clientDESKey.getEncoded(), "DES");
IvParameterSpec iv = new IvParameterSpec(clientDESKey.getEncoded());
sharedCypher.init(Cipher.DECRYPT_MODE, DESKeySpec, iv);
CipherInputStream cis = new CipherInputStream(new FileInputStream(WD), sharedCypher);
String time = ""+System.currentTimeMillis();
File outputFileW = new File("/tmp/new_wireless_data."+time);
System.out.println(System.currentTimeMillis()+": Output file is" + outputFileW.getAbsolutePath());
outputFileW.createNewFile();
FileOutputStream fos = new FileOutputStream(outputFileW);
byte[] putCypherBytes = new byte[8];
int i=0;
while((i=cis.read(putCypherBytes)) != -1) {
   fos.write(putCypherBytes, 0, i);
}Any thoughts on cleaning this up would be greatly appreciated.
Best,
Glenn

Well, I seriously doubt its the JDK or JCE. I dont have time right now to
download that exact version and test it, but instead I'll give you the code
I pieced together from your posts. Put your text to be encrypted in a file
called plaintext.txt in the directory you run the class in. The decrypted
text should be appear in new_wireless_data...
If you can run this without error, then your problem most likely lies
on your server-side.

Set a timeout for crystal sessions while using the Windows.Forms.Viewer?

Hi,
I am looking for a way to set the timeout for the crystal report sessions when using the Windows.Forms.Viewer in a .NET application. I guess that the default value is 20 minutes (like in the entperprise installations) but we cannot afford to keep many sessions open for that long. Is there a registry entry which can be set? Or even a way to do this programmatically?
Thank you in advance,
Stratos

Hi David,
we are talking here about a standalone .NET application where the reports are installed locally (like the application itself). We are not retrieving the reports from a server. The whole thing was developed using the crystal report viewer model probably because it was easier to do so. Is there a method in this model to tell the crystal runtime to do the clean-up work either for a report (like the ReportDocument.Close() ) or for the entire runtime instance. Dispose() does not seem to help us. If you say that there is no other way than redesign then we have to consider this option also.
Cheers
Stratos
PS: What I was thinking of (as Plan B instead of using the ReportDocument object model) is to instantiate the crystal report viewer object in a separate process (.exe). Please note that we open a new crystal report viewer windows for each report, which is displayed. Closing the viewer window (ie. terminate the process) will at least then clean up and release the crystal DLLs and hopefully close the database connections. Or am I missing something here?
