Re: multipart-request / file upload problem

[Adam Hardy]

Thanks for the exposÃ. :)  So it's worse than I feared! Well, I shall 
just come up with a convincing error message in those situations where I 
would have needed it, rather than try to force a square peg somewhere it 
doesn't want to go.

Ah, if I told you that, it wouldn't be a secret any more, now would it? ;-)

The biggest difference with multipart requests is that the request is
wrapped by Struts, so when you invoke a method on the request object, you
are actually invoking a method on the MultipartRequestWrapper class. This is
necessary so that calls to, for example, getParameter() go to Struts, which
parsed your request, rather than the container, which didn't.
In the code fragment below, I see you are invoking getParameterMap(). Note
that this is a Servlet 2.3 method. Since Struts 1.x is built for Servlet
2.2, that method is not implemented, and simply returns null.
Actually, there isn't a way to get the file items from the request itself,
since it doesn't have them. They're stored in the multipart request handler
itself. So, you would get the set of uploaded file items like this:
Hashtable fileItems =
formBean.getMultipartRequestHandler().getFileElements();
I'll be the first to admit that the current multipart implementation is a
little, um, arcane (not that I invented it ;). The plan is to completely
rewrite it for Struts 2.x, when we get there.
Hope this helps.

I'm going to put this another way: what's the secret with file upload 
requests? I can't see my file parameter in the request parameters when I 
submit the form with the multipart-request.

Re: File upload problem with Struts 1.1

[Martin Cooper]

This usually happens when you have your jars in the wrong place and your
container also includes (a different version of) FileUpload. Make sure that
the Commons FileUpload jar file, as well as the Struts jar file and other
Commons jar files, are in your WEB-INF/lib directory, and not in a
container-specific lib directory.

Hi,

 We are getting error while file uploading using struts 1.1. We have a demo
code for file uploading which demostrates the file uploading using struts.
When we run there application code works fine but  when we submit the form
by setting enctype for the form it throws the following error. (Remember we
are not doing anything in the action or in the form just getteer and
setters) so issue is with enctype settings. It may use some internal class
while sending data using enctype. Please advise us what to do.

We downloaded the sample file uploading code from :
http://forum.exadel.com/viewtopic.php?t=120

But according to me the problem can be with setting of enctype.

follwoing is the  code for our form

hi,
are you using a struts nightly build? it appears that might 
require a different version of commons-upload (cvs 
probably).

Re: File upload problem with Struts 1.1

[Garg Raman \(SDinc\)]

Hi Connor,

 Thanks for your reply. We have the commons-upload.jar in the lib of our
appliction directory and as well the struts.jar.

We also have set the Controller size to 2MB which is quite nice for any
file.

If you want to see the error coming itself we can pass on the URL for our
development server


Any other suggestion will be appreciated .

Looking forward to hear from you.

Re: File upload problem with Struts 1.1

[Caoilte O'Connor]

have you got the commons-upload jar in your lib dir? you 
need that as well as the struts jars.

Also check your controller (in struts-config) has something 
like this (though i think it's optional actually),

File upload problem with Struts 1.1

application code works fine but  when we submit the form by setting enctype for the

or in the form just getteer and setters) so issue is with enctype settings. It may use 
some internal class while sending data using enctype. Please advise us what to do.

We downloaded the sample file uploading code from : 
http://forum.exadel.com/viewtopic.php?t=120 

But according to me the problem can be with setting of enctype.

follwoing is the  code for our form

RE: file upload problem

Hi Brian, 

Thanks for replying. I really need help here, cause this is my first
time I am dealing with this.

All I wanted to know is how should and can I handle uploads of files
which are then being accessed intensively. 

Up to now I've seen two ways to do this:
(1) Store the uploaded files in the database and have a Struts Action
serve those files from the DB.
Pros: - The action has an ultimate control on who access what
- The files are better secured
 
Cons: - might turn up slow, even too slow to not acceptable

(2) Store those uploaded files under a file system directory and have
the JSP pages access these files through an Action or direct access,
like any normal image, logo, etc.
* Using an action - again, gaining control over the access, but might be
slower then direct access.
* Using direct access - probably faster (don't know how much more,
though), but losing control over pages access, less secured.

To do this I thought also of using Apache as the front door, using the
"alias" directive + JK2 module, which I guess you are familiar with.

Of course using Apache as the front door led me to the question of: "do
I need it really, is it that important to have the Apache just for the
files".
Many people argue that using Apache is best for static files, and I
guess images, photos, etc. *are* static in nature, so why not.

Still I did find that the configuration is a bit awkward, however it can
work. 

Do you use Apache for that as well? Or just Tomcat?

True, first I wanted to go along and delay my decision of how to access
those files and just have a file system directory. But I saw that JBoss
deletes those directories upon packed deployment. 

In your solution I have to deploy in an unpacked manner even in
production. Otherwise the whole directory will get lost. Do you see any
problems with your way?

It's really sad that there is not way to declare in JBoss/Tomcat a
directory with characteristics similar to the alias 
 in Apache. I don't see why it is not there, am I the only one
to deal with this kind of requirement? I guess not :)

Erez

Hi Erez,

Just wondering if you figured this out. I've found what I think could 
be a solution.

If you deploy your jboss ear in an exploded way:

[
>How can a war file be deployed in a exploded way .. 

just create a directory named foo.ear and in the deploy
directory,
and unpack your EAR file in foo.ear.
Then unpack the WAR file in a directory named foo.war in
foo.ear.
]

then you can write the uploaded files to a folder that the tomcat server

will be able to serve!

This works for me. Email me for more details.

Hi all,

I'm trying to do a file upload action based on the example
struts-upload.war.

I want to save the uploaded file to a folder on disk. However when I try
to run 
the action I get an error saying I don't have access to the folder. I've
tried 
changing the folder access and also using a different folder. 

I still get a file not found exception which says 

java.io.FileNotFoundException: .. (Access is denied)

I'm using JBoss 3.2.1_tomcat4.1.24. 
Perhaps JBoss restricts folder access?

The code that runs the struts action is:-


AddProductForm frm = (AddProductForm) form;

//retrieve the file representation
FormFile file = frm.getTheFile();

//retrieve the file name
String fileName= file.getFileName();

//retrieve the content type
String contentType = file.getContentType();

//retrieve the file size
String size = (file.getFileSize() + " bytes");

log.info("File details - name: "+fileName);
log.info("File details - contentType: "+contentType);
log.info("File details - size: "+size);


// this is where I get the folder path to save the image into.

String imageStorePath = Init.getImageStorePath();
log.info("the value of imageStorePath is: "+imageStorePath);

try {
//retrieve the file data
ByteArrayOutputStream baos = new ByteArrayOutputStream();
InputStream stream = file.getInputStream();

//write the file to the file specified
OutputStream bos = new FileOutputStream(imageStorePath);
int bytesRead = 0;
byte[] buffer = new byte[8192];
while ((bytesRead = stream.read(buffer, 0, 8192)) != -1) {
bos.write(buffer, 0, bytesRead);
}
bos.close();
log.info("The file has been written to \"" + imageStorePath
+ "\"");
//close the stream
stream.close();
}

catch (FileNotFoundException fnfe) {
log.error("Couldn't find the file: "+ fnfe.toString());
}
catch (IOException ioe) {
log.error("io exception: "+ ioe.toString()); 
}
finally{
//destroy the temporary file created
file.destroy();
return mapping.findForward( WebConstants.SUCCESS );
}
}


Any help would be greatly appreciated.

Yes.

I'm a strong proponent of storage in a database.  Not only is a BLOB the

ultimate quarantine but it saves you the headache of keeping meta-data 
and and the file content in synch.  Most RDBMs implement BLOBs as files 
so there is very little performance hit when you perform the upload.  
When users perform the download you will need an action to 'proxy' the 
bytes from the database to the response.  If you write good java.io 
code, set the content type on the response and return null from the 
execute method this is pretty straightforward and fast enough for most 
applications. 

Downloads will be a little slower this way but it's rare for system 
requirements to necessitate repeated file download.  If _each_ file is 
going to be downloaded more than a few hundred times/day you might want 
to write it to directory served by your _web_ server.  

Don't forget virus protection.  If users can upload and download MS 
Office documents you will need to virus check them after they are 
uploaded but before anyone else can download them.

I doubt something is out there that could actually scan BLOBs, 
especially platform independently.  I've yet to even find a "type-4" :) 
virus checker.  Instead, I've used a J2EE application client on a 
separate machine from the production server.  This client uses a native 
virus scanner to check the files.  Once the file is checked the app 
client sets a flag on the EJB allowing users to see the file.

File Upload problem and Size Validation

[Hemanth Setty]

Hi all,
I am havig a problem on FileUploads in RC1...This problem occurs when I 
use the FormFile feature of struts. If the size of the file is lesser 
than the limit specified by the controller, everything seems to work 
fine...but when the size exceeds the limit then it fails on the 
validate() method of the form. But it does not redirect back to the same 
page. It returns to any empty page. The log level of debug shows correct 
redirects and even debug statements on the jsp prints out.. I dont know 
what the error could be.
I even tried the same thing with the struts-upload webapp that comes 
with RC1 and it was doing the same thing.
Any suggestions.??
Thanks
Hemanth

RE: file upload problem

[Nicolas Robert]

Hello Mark,

Before upgrading my struts to beta 2, I was using DiskFile class in my form
bean to store the uploaded file.
After an upgrade to beta 2, the DiskFile class throws your exception.

If you use a DiskFile class to, my solution is to used instead a FormFile
class to store uploaded file.

hello again,

so i am trying to implement a file upload feature in my application, and i
think i have everything setup correctly, but i am getting this error on
submission.

javax.servlet.ServletException: BeanUtils.populate
java.lang.IllegalArgumentException: argument type mismatch

i feel that this might be due to the type of the file field in the Form
object.  right now it is string (as is everything else). 

should the file type is a form object be something different?

thanks,
mark

I would strongly encourage you to move to Struts 1.1-b2 if you can. It uses
a new file upload implementation which is faster and much more robust than
the one in 1.0.2. No code changes are required on your part, since the
interface is the same.

You mean FormFile. ;-)

You mean using getFileData()? That's OK as long as you are completely sure
that the file is always going to be small. However, if you might ever have
to process a large upload, then you should use getInputStream() to avoid
running out of memory. Once you have the input stream, you can do whatever
you like with it. Do remember to close it when you're done, though.

RE: file upload problem

[Mark Silva]

I am using version 1.0.2.  

i went and looked at the example, and found my answer, FileForm.

now i have another question, that may be a silly one, but is there any reason I 
shouldn't turn the contents of the FileForm into a String, and then run 
StringTokenizer over it?  This is a csv file, that i am importing into the database.

thanks,
mark

What version of Struts are you using?

You should take a look at the sources for the struts-upload sample
application that comes with Struts. That will give you a working example to
refer to.

RE: file upload problem

[Galbreath, Mark]

It's really difficult to help without seeing your code.  Are you using
 in your ?  I don't know anything
about BeanUtils, but if it acts like java.util.Properties, the key and value
are both strings.  File uploads are of type multipart/form-data (see
experimental RFC 1867) and you retrieve it in the servlet with

  public String MultipartRequest.getParameter( String key);

See: Jason Hunter, "Java Servlet Programming, 2d ed.," pp 119ff.

hello again,

so i am trying to implement a file upload feature in my application, and i
think i have everything setup correctly, but i am getting this error on
submission.

javax.servlet.ServletException: BeanUtils.populate
java.lang.IllegalArgumentException: argument type mismatch

i feel that this might be due to the type of the file field in the Form
object.  right now it is string (as is everything else). 

should the file type is a form object be something different?

Struts 1.0.2 file upload problem, was working with Struts 0.5

I am in the process of upgrading our application to struts 1.0.2 from
struts 0.5 ( I know it should have been done a lot earlier but still ... )
Everything is working as excepted except for this one problem when I try to

If any of you have any clues why I am getting this error it would greatly
help me. Again this feature used to work with the older version of struts

RE: File Upload Problem.

[SCHACHTER,MICHAEL (HP-NewJersey,ex2)]

Marli,

Your multipart data seems to be right. Make sure you prefix it with
the normal HTTP headers that go with a multipart request, I think something
like:

Content-Type: multipart/form-data; boundary=...\r\n
--boundary
 -same stuff as you had for the multipart data goes here

If you're still having this problem, would you mind sending me the stuff
that you're using so I could take a look at it?

Hi Marli,

No, you should be able to use the struts utils in your servlet. You will
have to manually create a FormFile however. Look at the source for the
html:file tag.

Hi Mike, I tested both with IE 6.0 and Netscape 4.5.
Both give the same problem.

Any idea whether I'm sending the CRLF correctly ?

RE: File Upload Problem.

[SCHACHTER,MICHAEL (HP-NewJersey,ex2)]

Hi,

What browser are you using to submit the form? Also,
you may already be aware, but as mentioned by the
other reply there's an easy way to handle multipart
form data in Struts, you can check out the struts-upload 
webapp in the distribution for an example.  

As with your use of MultipartIterator, I'm not sure what 
the problem could be there.

Hello,

I was writing some upload code to test the use of  MultipartIterator class.

My html code is as follows:
-

 MULTIPART TEST


CLASS: 

COMMAND: 

DATA (XML): 

File Location: 







My servlet code is as follows:
---
 protected void doPost(HttpServletRequest req, HttpServletResponse 
resp)
 throws ServletException, java.io.IOException
 {
  LogUtil.debug(_Class, " -> DO POST");
  MultipartIterator iter = new MultipartIterator(req, 64*1024, 
Integer.MAX_VALUE, "C:/Temp");

  MultipartElement elem = null;
  while( (elem = iter.getNextElement()) != null )
  {
 if( elem.isFile() )
 {
System.out.println("ELEM is a file");
System.out.println("FILENAME = " + elem.getFileName());
System.out.println("FILE PATH = " + 
elem.getFile().getAbsolutePath());
 }
 else {
System.out.print("NAME = '" + elem.getName() + "'");
System.out.println(". VALUE = '" + elem.getValue() +
"'");
//System.out.println(elem.getName() + " = " + 
elem.getValue());
 }
  }

 }

When I use my browser to the html file, put some data in the "dataParam" 
text area and
hit Submit,  I got the following result in Tomcat stdout.log

NAME = 'class'. VALUE = 'File'
NAME = 'cmd'. VALUE = 'Add'
'sword>bejo1663eb7d56063ec67f23be
ELEM is a file
FILENAME = ch-p506-2_enable_callhome.cfg
FILE PATH = C:\Temp\strts4674.tmp
NAME = 'SUBMIT'. VALUE = 'Submit Query'

My question is:
--
* Is there an explanation on why the "dataParam" parameter is not printed
out,
or printed out but has the wrong value ?
* I also have written a Java multipart writer to test it, but it looks like 
that the file is always
   larger by 2 bytes. Isn't the format for multipart request like this:
   --Boundary\r\n
   content-disposition: form-data; name="blah"; filename="file.txt"\r\n
   Content-type: application/octet-stream\r\n
\r\n
Body goes here..
   --Boundary--\r\n
   Am I correct about the CRLF (\r\n) ? I have read RFC 1867 and RFC 2046 
and it looks correct.
   Any ideas ?

Thanks in advance.
Marli.

Hi Marli,

I might be missing something here, but you don't appear to be using struts.
Are you aware that there is a strurs tag for file upload? Have a look at the
struts examples.

Jon.

File upload problem in Struts 1.0

[Imran Zafer]

We have recently switched to Struts 1.0 from a previous beta version.
After migrating we are having problems in uploading certain files. The
files do get uploaded to the server but the contents get corrupted some
times. We further investigate this problem and found out that files get
damaged when they contains non-English content. E.g. if we upload a
Microsoft Excel file that contains non-English characters it got
corrupted, and we are unable to process that file with MS Excel
afterwards. The problems disappears if we switch back to old struts.jar
file.
 
Any ideas how to fix this problem. Is it safe to replace the struts.jar
file with old one as in interim solution?.

RE: File Upload Problem

[Darryl Pentz]

Just to confirm to the NG that we do seem to have a problem with the way
that org.apache.struts.upload.MultipartIterator.java does the
createLocalFile(). I've tested this quite a bit today and have found that
Struts-b1 worked fine with this spreadsheet. Thereafter, the
createLocalFile() was COMPLETELY redesigned and it's also with this redesign
that the spreadsheet gets corrupted.

The change fixed the problem some found uploading ZIP files (including
myself) but this new problem persists.

thanks,
Darryl

That's just it. We HAVE upgraded to Struts 1.0 final. This fixed a problem
we were having with ZIP files but now it seems we can't view spreadsheets

fine, but when you try and view them, Excel can't open them up.

Hi all,

Has anyone else experienced problems with the file upload lately? I'm
finding that uploaded files are being corrupted. It doesn't seem to matter
what type the document is. I've found an Excel spreadsheet and a Word
document that have displayed problems. It seems, doing a binary compare,
that a 0A is being inserted arbitrarily. I'm looking at
MultipartIterator.java as the possible culprit as that's where a 0A ('\n')
is being inserted.

If anyone can point out the error of my ways I'd appreciate it. I don't know
why we're only finding this problem now since we've been testing uploads
regularly. Unless it has to do with the fixes in 1.0 final that maybe broke
something. I'm a little out of my depth here since I'm still fairly new to
the intricacies of Struts.

thanks,
Darryl

Subject: File Upload Problem


Hi all,

Has anyone else experienced problems with the file upload lately? I'm
finding that uploaded files are being corrupted. It doesn't seem to matter
what type the document is. I've found an Excel spreadsheet and a Word
document that have displayed problems. It seems, doing a binary compare,
that a 0A is being inserted arbitrarily. I'm looking at
MultipartIterator.java as the possible culprit as that's where a 0A ('\n')
is being inserted.

If anyone can point out the error of my ways I'd appreciate it. I don't know
why we're only finding this problem now since we've been testing uploads
regularly. Unless it has to do with the fixes in 1.0 final that maybe broke
something. I'm a little out of my depth here since I'm still fairly new to
the intricacies of Struts.

thanks,
Darryl

I just got done fighting this problem for the last week.  Upgrade to struts
1.0 and that will solve your problem.
