JSP Multipart Form File Upload
Good morning to all.
I searched and googled but camu up with little.
I want to upload a file from an HTML form. I have the enctype set etc. I am receiving all of the data on the server boundaries and all. I know there are readymade packages to do this but I'm one of these types that like to know why something works instead of simply plopping a jar on the server and using it (STD java excepted).
My question is how to parse the data. If you read line by line, looking for the boundaries and you are trying to store the file bytes don't the bytes get corrupted when converting to String (in reader.readLine()) if they are not STD ASCII chars?
Can anyone point me in the direction of a good tutorial on the subject?
Thank you in advance.
ST
The basic idea of sending binary data via HTML is to encode into BASE64. This basically involves turning 3 bytes (8-bit) into 4 bytes (6-bit). This is done by representing a 6-bit byte with an ascii character. Instead of me confusing you I've found some code that does it, with lots of helpful comments.
[url http://ostermiller.org/utils/Base64.java.html] dont know if this code works but hey, it looks the part

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.

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.

JSP : latest JSTL, File Upload from web form Client to Server Question!
I understand that within a JSP, It is possible to read a file from the Client by opening a Stream somehow.
How do I code, within jsp/servlet (non tag) java code inside <% %>
blocks, WITHOUT openening a new connection to the URL, an InputStream from a client web browser form, from a file upload coded using
<input type="file" name="file1"/> ?
I have previously achieved this quite simply with a FileInputStream
with the previous version of JSTL.
How may I do this with the latest version of JSTL, with this index.jsp?
-with a simple text file.
-with a Binary file (with DataInputStream)?

However, these is some HTML/POST related content around what multiple readLine();

Is there an easy way, like using "${param.file1}",
aside from [http://commons.apache.org/fileupload/|http://commons.apache.org/fileupload/],
maybe using servlet style code, to get the File contents from a remote Client,
to the remote Server servlet engine, AVOIDING ANY SUPERFLUOUS CONTENT,
using version 1.12 of the JSTL, JSP 2.0,Tomcat 6?
Just politely, yes, no, and how?

RE: HTTP File upload using WebEnterprise
AFAIK, WebEnterprise does not support the multipart-mime file upload
feature. I think this is something that is targeted for the next
release.
On a project here we wrote our own cgi program to handle file uploads,
but unfortunately this was not integrated with the rest of the Forte
backend. The suggestion from Forte was to make C++ calls into our Forte
service objects from our CGI. We haven't yet implemented this, but it
certainly seems like it will be possible.
By all means, let us know if you find a better mechanism than this.
It's certainly not the cleanest in the world.

Searchable thread archive <URL:http://pinehurst.sageit.com/listarchive/>Hi,
You should have a parameter called ServiceName in your request
(either in the URL or as a hidden parameter in the form) for any request
you send to fortecgi. The cgi uses this information to send your request
to the proper forte application.
In your example you would need something like this
<FORM ENCTYPE=3D"multipart/form-data" ACTION=3D"...." METHOD=3DPOST>
Send this file: <INPUT NAME=3D"userfile" TYPE=3D"file">
<INPUT TYPE=3D"submit" VALUE=3D"Send File">
<INPUT TYPE="Hidden",Name="ServiceName",Value="MyService">
</FORM>
MyService is the name is the name you have given for the service when
you call EnableAccess in your subclass of HTTPAccess.
This is all explained in the Web Enterprise /SDK manual.
Note : You would also need a parameter PageName when using Web SDK. I
have not used Web Enterprise yet but I presume it is the same there too.
Hope this helps

Hi there,
I am experiencing some problems with a WL 5.1 sp8 server trying to do a
form (multipart/form-data) upload of a file.
I am using the com.oreilly package but get a Corrupt form data error
when instatiating the MultipartRequest object in the contructor of the
MultipartParser
Object.
Have anyone solved this on a WL 5.1 using the IIS plugin??

Unable to install File Upload Utility in AIX system
Hello,
I installed the Forms File Upload Utility, through CGI, following the steps described in the html
document provided with the utility. That is:
- i copied the files UploadClient.jar.sig and UploadServer.jar to the directory
/ias102/6iserver/forms60/java;
- i edited the .profile file, for the variable CLASSPATH to include the forms60/java directory:
CLASSPATH=/ias102/6iserver/forms60/java:/ias102/6iserver/forms60/java/UploadServer.jar:/ias102/6iserver/discwb4/classes/locator.jar:/usr/java131/jre/lib/rt.jar:
- i edited the .profile file, for the variable PATH to include the requested directories (Forms \bin and \bin\classic):
PATH=/ias102/6iserver/lib:/ias102/6iserver/bin:/usr/java131/jre/bin/classic/:/us
r/java13
1/bin:$PATH
(i also tried editing the CLASSPATH and PATH variables in the forms60.sh and forms60_server files)
- on my machine (client machine) i installed the PJC.x509 certificate;
After this installation, i included the Demo Form provided with the utility in my test application, and then i executed
the form.
I tried to upload a file but i got the following error: "FRM-40735: WHEN-BUTTON-PRESSED trigger raised unhandled exception ORA-06508"
I looked in the html document, in the "Troubleshooting" section, and i did a test pressing
the Key-Listval (Control+L by default), that would pop up a dialog containing
the current CLASSPATH, but instead i got the following error:
"FRM-40735: KEY-LISTVAL trigger raised unhandled exception ORA-105100."
In the html said that "If this fails then this is because Forms cannot instanciate any Java code
at all".
Do i need to add any more environment settings?
Thanks, JorgeThere are probably several environment variables which need to be set in order for the Forms runtime to communicate with Java. However, to where they point will depend on which Java home you choose to use. For Forms 6.x, you must use the equivalent of JDK 1.1.8 or 1.2.2. These versions are included in the Oracle home. If you try using a newer version (like the one installed on the OS) you will likely have problems.
Verify these env variables point to the appropriate locations to use the jdk/jre in the Oracle Home:
PATH
CLASSPATH
LIBPATH
LD_LIBRARY_PATH
JAVA_HOME
Additionally, ensure that your CLASSPATH includes references to the following jar files:
importer.jar
rt.jar -
Struts file upload without interMedia under ADF
Can this be done ?
I have an existing table with the following columns:
Content BLOB
MimeType VARCHAR2
FileName VARCHAR2
and moreVery frustrated :(
Trying to find an answer to my question above.
If I Add a transient OrdDocDomain to the Entity/View Layer.
Map this into the UIModel (drag-drop onto JSP as struts file upload) so a FormFile object is available in the struts Action layer.
Override 'processUpdateModel' so I can obtain a reference to the FormFile object.
In the commit event of the Action class, take the referenced FormFile and set the BLOB like follows;
newRow.setAttribute("FileData",
new BlobDomain(uploadFile.getFileData())
Then call into the internal commit operation.
The following exception is raised;
04/11/19 07:32:18 java.lang.ArrayIndexOutOfBoundsException: 0
04/11/19 07:32:18 at oracle.jbo.client.remote.OrdClientPostListener.notifyClientPostAfter(OrdClientUtil.java:135)
04/11/19 07:32:18 at oracle.jbo.client.remote.ApplicationModuleImpl.postChanges(ApplicationModuleImpl.java:796)
The transient OrdDocDomain has registered a listener.
How can I remove this listener. The transient has a method 'removeListenerFromTransaction()' with the comment 'Internal: Applications should not use this method.' and no other references ?
Does anyone know how the listener can be removed or better still, not be registered with the transaction. -
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.

File Upload with jsp & MultiPart
Hi all,
i've got a problem uploading a file from a multipart form.
The file is correctly uploaded and i can open it, but I can't get the file name,
In multipart.jsp fileName print out a null.
Below the code. Can someone telle me where the error is?
Thank's
Kalvin
this is the first page:
prova.jsp:
<form name="frmUp" action="multipart.jsp" method="POST" enctype="multipart/form-data">
<input type="file" name="file"><br>
<input type="submit">
</form>
multipart.jsp:
<%
String fileName = request.getParameter("nomeFile");
String pathFile = "/myPath/";
InputStream is = request.getInputStream();
out.println("File name:"+fileName+"<br>");
UploadFile uf = new UploadFile(pathFile, fileName);
if (uf.upload(is))
out.println("OK<br>");
else
out.println("NO OK <br>");
%>you have to get the filename from UploadFile object probably. You definitely can't get it from request cuz multipart forms are handled specially. If it saves the file properly, then it's probably assuming a null filename means to use the name as it was uploaded, but UploadFile should be able to give you a File object for where the file was put.

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)

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? -
Difficulties in creating a JSP for File upload
hello out there,
im trying to create a ProcessUpload.jsp File which should handle a file upload from a channel in the portal. regarding a previously posted thread acording to fileupload i deployed this jsp-file in the regular webServerHierarchy so that you dont have to go into the desktopServlet Portal, which cant handle fileUpload.
its location is this ../portal/test/ProcessUpload.jsp and it uses CustomTags referecens from /portal/WEB-INF/test.tld. i customized the deployment descriptor in /portal/WEB-INF/web.xml as well. but as soon as i try to put a taglib which uses this custom tags the server responses with an error.
does anybody know how to deploy a global jsp file to handle file uploads, or something in particular how to deploy jsp with custom tags outside the desktopservlet but inside the portal webapp??
i would be really thankful ;-)
best regards
martinhi alex,
i allready tried to realize a channel with file upload download. channels are made up of jsp pages and when i am forwarding my form with enctype="multipart/form-data" encoding the desktop-servlet intercpets my entity-body.
so what kind of channel you have thought about ??
thanks for reply ;-)
