File upload issues
Hi all,
I was reviewing the state of ontologymanager Web resources and others
after the Clerezza Jena TDB bundlelist was added (thanks Rupert!).
I'm almost sure it's unrelated to the above, but most OntologyManager
ontology loading service (via POST Multipart Form Data) seem to fail on
my setting. Uploaded files do not seem to be created locally.
If I look at:
https://svn.apache.org/repos/asf/stanbol/trunk/ontologymanager/web/src/main/java/org/apache/stanbol/ontologymanager/web/resources/OntoNetRootResource.java
in the performLoadOntology() method I used to be able to get a POSTed
File like this.
file = new File(data.getFormFileParameterValues("file")[0].getFileName())
where data is a org.apache.clerezza.jaxrs.utils.form.MultiPartBody - one
of the things that I guess must have changed during the commons-ng move.
Trying that again now, both file.exists() and file.canRead() return
false - even after launching Stanbol with -no-security . No idea where
POSTdata from a file input are going.
I cannot find other Stanbol Web services that support fileupload so I
can compare against them. Do we have any others currently in trunk?
Many Thanks
Alessandro

Thanks very much, the archetype does work but it uses the byte array
from FormFile.getContent() rather than trying to create a File object.
Now that I'm checking it, FormFile.getFileName() is really just the
filename without a local path, so I guess it needs a tad different
handling than the old Jersey implementation. I'll patch the
ontologymanager.web resources to use byte arrays instead, looks like the
way to go.
Many Thanks
Alessandro

Hi Alessandro
Just from the code of your email you seem to be doing things right. The
method you're using should work both with 0.12 as well as with 1.0.0 (in
0.12 it was still possible to use a jersey specific method, but thta's not
what you're doing).
For a working example of file upload try out the stanbol-stateless-webapp
maven archetype (if this doesn't work, then it's definitively a bug).
Cheers,
Reto

Hi Alessandro,
AFAIK the multipart mime code in 0.12 depends on a Jersey specific
extension to JAX-RS. Because of this Stanbol could only be used with
Jersey and no other JAX-RS implementation. This was the reason why
Reto chanted this in the stabbol-ng branch to use the Clerezza
implementation for handling multipart requests.
I have never used this, as the Stanbol Enhancer consumes multipart
requests using custom code that does allow streaming of the request
data. Reto should be able to answer your question. Maybe you want
also to ask your question on the Clerezza Mailing list.
best
