Multipart File Upload

[DeepEdward]

Hi,
I have tried the multipart file upload with spring webMVC which works fine there.
On integrating the same with webflow it works fine, but when i exceed the file size limit then i get the error :

exception

I googled it and found that this had been reported as a bug,
(see link, http://jira.springframework.org/browse/SWF-212)

Please lemme know if this is fixed? or any way out for this issue?

Rgds,

[DeepEdward]

Haven't come across a single answer to file upload yet, is there any fix for this?
On upgrading my Spring webflow jar, i get the error as specified in the thread(http://forum.springframework.org/showthread.php?t=54462). I am currently using version 1.0.5

Pls give a solution for this, if anyone came across this.

Regards,

Hi,

I have upgraded my Spring Webflow Jars from 1.0.5 to 2.0.2, and the Spring jar to 2.5.5.

Uploading the file using the previous version of webflow was not working for me, but the same worked when using just spring web mvc.

Now on upgrading the webflow jar, I am getting the following Exception:

Has anyone come across this issue...
Please let me know if there are some more changes to be done to implement the multipart upload functionality with SpringWebflow2.0.2

Is there a way to solve this..
I am stuck with this problem.
It seems that the apache commons-fileupload jar tries to clear the file to be uploaded(which it cannot find in the temp folder), and throws the FileNotFoundException.

Please let me know if this can be resolved, as uploading is a very important feature for me.

I think your problem is related to an error in the binding process. Swf2 is not using mvc for binding request parameters to properties in the model and they have a problem related to binding MultipartFile parameters. See this post and let me know if helped you.

http://forum.springframework.org/sho...ight=multipart

[DeepEdward]

If the problem would have been in the binding process then I think the File to be uploaded, would not have uploaded at all.

On changing the property to byte array type as specified in your post, I get the same exception. The problem I am facing here is, if the file is a small text file, it gets uploaded without any exception.

But when the file to be uploaded is big in size (like a pdf file or a video file) then I get this error. Though, this exception is thrown in this case, the file gets uploaded.

I think the problem is the commons-fileupload jar used by spring, which tries to clean up the temp folder for the specified file, on which it throws this error.
