submission with xml data and file upload ?

Hallo all,

I wonder how to upload files and XML data in one submission?
The XML data and uploaded file has to be validated and saved in one transaction on the server-side.

After submitting my instance data, a servlet reads out the XML data from the request input stream.
<xforms:submission id="submit_1" method="post" ref="instance(employee-instance)" resource="http://localhost:8080/test/submit"/>

To upload files I have to set the submission serialization to multipart/form-data to read out the uploaded temp file.
<xforms:submission id="submit_2" method="post" ref="instance(file-instance)" resource="http://localhost:8080/test/submit" serialization="multipart/form-data"/>

But with multipart/form-data I cant read out the XML data any more because the content of the server is a isMultipartContent of all single form fields.

How can I achieve to send and read out the XML data and file together?

Thank you for your help,
Karolin

Karolin,

The first question is how would you like this to be done at the HTTP
level? One way is to use a multipart/form-data with 2 parameters: the
file (as you do now) and the instance. So in XForms, the instance you
submit would look like:

<instance>
<file>...</file>
<employee>...</employee>
</instance>

Inside <employee> you have a serialized version of instance
('employee'). You can populate the value of that element with a
<xforms:setvalue>, using saxon:serialize(instance('employee', 'xml')),
that you run just before doing the submission. Could this work for you?

You need submission method="multipart-post" which uses serialization multipart/related.
http://www.w3.org/TR/xforms11/#serialize-multipart
It's not clear that Orbeon implements this currently, though.

Leigh,

Yes, but unfortunately the multipart/related serialization is not yet implemented.

In reply to this post by Alessandro Vernet

Hey Alex

Unfortunaltely its not working. With
serialization="multipart/form-data" I get all input fields of my xform
and not the instance data.

Do you know when the serialization type multipart/related will be
implemented?

Thank you very much for your help,
Karolin

</instance>

Inside <employee> you have a serialized version of instance
('employee'). You can populate the value of that element with a
<xforms:setvalue>, using saxon:serialize(instance('employee', 'xml')),

that you run just before doing the submission. Could this work for

Re: Antw: Re: submission with xml data and file upload ?

Karolin,

We have no ETA yet for implementing multipart/related. Most likely it
will be implemented if we need it badly for a project or if somebody
sponsors the feature.
