File uploading to temp folder

Hi,

I've a Xforms document with a <xforms:upload ...> and I've written a REST service for uploading the file.

REST service is receiving the request, but the file is getting uploaded to TOMCAT_HOME\temp folder.

Even I removed the submission element's resource value then also the uploading to temp file is happening (I don't know who is uploading behind). When I inspected the source code, the html <form..> tag's action is set to my application context path.

Files in my application:

apps\my-upload\page-flow.xml :

<config xmlns="http://www.orbeon.com/oxf/controller"

xmlns:oxf="http://www.orbeon.com/oxf/processors">

<page path-info="/my-upload/" view="view.xhtml" />

<epilogue url="oxf:/config/epilogue.xpl"/>

</config>

apps\my-upload\view.xhtml : http://pastie.org/409126.txt

In the above view.xhtml, the resource atrribute of submission is kept blank intentionally (actually it is http://localhost:8182/upload; my upload REST service)

Please let me know if I m doing some this wrong or if any one has succeeded in implementing the above, please share the code.

Re: File uploading to temp folder

isn't it possible to upload (type: multipart/form-data) file just specifying REST service (without using xpl or URL generator) ?

I googled googled for file uploading in Orbeon with REST.... no clear sign... I end up writing my own REST service and it is accepting multipart/form-data type uploads and working correct.

But when used with Orbeon no luck. I m usig both 3.7beta1, nightly builds.

In nightly builds I hear multippart/form-upload is working fine. Yeah it is working fine but the temporary file path is only coming (used serialization="multipart/form-upload")

I need this for the client demo in the coming 2 days.

If some knows about this, I'll glad to hear from them

Thanks,

Re: Re: File uploading to temp folder

Hi,

The xforms-upload example uses a bind with xs:anyURI which makes the selected file being uploaded to a temp directory.
You can also use xs:base64Binary which will make the file being embedded encodedly in the xml document.

Not sure I understand this question. Please clarify what you intend to
do.

multipart/form-data will serialize any field with xs:anyURI or
xs:base64Binary type as a part. On the wire, the data is serialized
and there should not be a reference to temporary files if the type is
properly set.

If the receiving side is Orbeon Forms, then the request processor
makes every uploaded file available as a temporary file again.

Thanks Jeroen. I've used that but no luck as I need to upload to another folder, not to temp folder.

From the doc/spec, xml encoding is not preferable for larger size files, which results much more increase in size, and suggested to use multipart/related (as multipart/from-data is old one).

I've used xs:anyURI (which they suggested) and given url of the REST service (deals with the multipart/form-data upload) but the content type receing is application/xml (this should be when I use xs:base64Binary. Is n't is?)

Not sure I understand this question. Please clarify what you intend to do.

Please see the view.xhtml code in http://pastie.org/410080.txt

The submission resource is the REST service I wrote to handle the multipart/form-data (I've tested this by uploading a file using normal html form upload).

I've used <xforms:bind nodeset="file" type="xs:anyURI" /> too. Even then also I m getting media type as application/xml, and the REST service is returns bad request header. I suppose the media type should be multipart/form-data. Isn't it???

multipart/form-data will serialize any field with xs:anyURI or xs:base64Binary type as a part. On the wire, the data is serialized and there should not be a reference to temporary files if the type is properly set.

If the receiving side is Orbeon Forms, then the request processor makes every uploaded file available as a temporary file again.

What does this receiving side? If I got it correct, I m not using any Orbeon/XPL for uploading. Simple REST service.

I saw some replies from mailing list to use file serializer with url processer. I m trying to figer it out. Will this solves my problem? please share the way of doing so.

Thanks,

Re: Re: Re: File uploading to temp folder

Below is the request body received by service:

POST /upload HTTP/1.1

Cookie: JSESSIONID=57CE3140873C75E43CEB9377C273C9C1

Content-Type: application/xml

   size="1314486">

       file:/C:/Tomcat6/temp/upload__3efec1c_11fdfcc8ec5__7ffc_00000512.tmp

</file>

Now I m trying to use the XPL to copy the temp file to the required location.

As far I know I need to use file serializer to read the above response and copy to the required location:

<p:processor name="oxf:file-serializer">
  <p:param name="instance" type="input"/>

  <p:input name="config">
   <config>
    <directory>file:///e:/docs_upload/</directory>
    <file>single-file-doc.html</file>
    <make-directories>true</make-directories>
    <append>false</append>
   </config>
  </p:input>
  <p:input name="data" href="#instance"/>
</p:processor>

but I m not able to guess where do I need to place this. (I've tried this placing in the 3.7 beta1 bundled upload example's 'do-background-upload.xpl' file. but nothing happening).

Litter confusion! Even I removed all the files and just with the view.xhtml & page-flow.xml the file is uploaded to temp folder. how is this possible?

Am I making a BIG mistake some where?

First, the support for file uploads with multipart/form-data has been
implemented very recently. So you'll need a recent nightly build for
this. With a nightly build, you can do it directly in XForms, with an
<xforms:submission>.

Second, it is hard to get a clear picture of what you are doing and
what goes wrong. Could you send us some code that runs in the XForms
sandbox example? We don't need to have a real service on the other
side to catch the file; you can do the submission to any web site and
we can check the HTTP traffic to see if the right content is sent over
the wire.

I've mentioned the source file link in the above mail. Any way http://pastie.org/410080.txt is the link.

Sorry, I missed it. You just need:

1) To add a serialization="multipart/form-data" to your <xforms:submission>.
2) To add a <xforms:bind nodeset="/file" type="xs:anyURI"/>.

And here is modified file.
