Multipart and WebClient
I need to take an incoming file and send it to a third party. For
memory purposes, I'm dealing with InputStreams on the fly. I've copied
the code essentially from the jaxrs Multipart page on the CXF website,
from the section uploading files....
WebClient client = WebClient.create(<endpoint removed>)
.accept(MediaType.APPLICATION_JSON)
.type(MediaType.MULTIPART_FORM_DATA_TYPE);
ContentDisposition cd= new ContentDisposition("form-data; name=\"file\";
filename=\""+consult.getFilename()+"\"");
Attachment att = new Attachment("file", new ByteArrayInputStream(file),
cd);
MultipartBody body = new MultipartBody(att);
String resp = client.post(body, String.class);
However, when I run this code, I get:
No message body writer found for class : class
org.apache.cxf.jaxrs.ext.multipart.MultipartBody
Am I using the wrong class or did I not configure something correctly?
Any help would be greatly appreciated.
Thanks!

Re: CXF 2.3.3 - JSON output - java.lang.IllegalStateException: Invalid
JSON namespace
Posted by Sergey Beryozkin <sb...@gmail.com>.
I updated CXFNonSpringJaxrsServlet to support the injection of simple
properties for service and Application classes, providers and
interceptors, few people have asked about it, Carl-Eric, others, so it
makes sense to add some simple support, ex:
<init>
<param-name>jaxrs.interceptors</param-name>
<param-value>
org.bar.MyClass
(property=value, property2=value)
</param-value>
</init>
MyClass is expected to have setProperty and setproeprt1 methods, with a
primitive or List class type
Cheers, Sergey

Hi
The default Jettison provider expects a namespace-to-prefix map set up.
If you don't realy need the prefixes on the receiving end then the
simplest option is to configure JSONProvider with an "ignoreNamespaces"
property, otherwise you'd need to provide a map, here is more info:
http://cxf.apache.org/docs/jax-rs-data-bindings.html#JAX-RSDataBindings-ConfiguringJSONprovider
The thing is how to configure it given that you are using
CXFNonSpringJAXRSServlet.
One option is to extend JSONProvider and only set "ignoreNamespace" or
"namespaceMap" property as needed on the superclass. And register it
with the servlet using a jaxrs.providers parameter.
Another option is try registering Jackson.
I should probably do some enhancement for users be able to set simple
properties on providers registered from web.xml...
Cheers, Sergey

I got that fixed, only xsi:type was blocked, now both xsi:type and

RE: CXF 2.3.3 - JSON output - java.lang.IllegalStateException:
Invalid JSON namespace
Posted by "Muller, Anthony" <an...@sap.com>.
Hello,
I tried to remove:
final Map<String, String> namespaces = new HashMap<String, String>();
namespaces.put("http://www.w3.org/2001/XMLSchema-instance", "xsi");
setNamespaceMap(namespaces);
And to add:
setWriteXsiType(false);
However, it failed... (same error than previous one)
Regards,
Anthony

Hi
That is great, just for your info, "writeXsiType" property, if set to
false, can probably block that xsi:null...
You may also want to experiment with Jackson which is probably is less
dependent on the way JAXB operates, as opposed to Jettison
Cheers, Sergey

Hi
That is great, just for your info, "writeXsiType" property, if set to
false, can probably block that xsi:null...
You may also want to experiment with Jackson which is probably is less
dependent on the way JAXB operates, as opposed to Jettison

RE: CXF 2.3.3 - JSON output - java.lang.IllegalStateException:
Invalid JSON namespace
Posted by "Muller, Anthony" <an...@sap.com>.
Hey Sergey!
I found a solution to my issue after many attempts and after be sure that my provider was called by CXF.
I tuned the OSGi imported packages too.
I think the problem was for interpretation of XSD Nillable value. Even if I set 'ignoreNamespaces' to 'true', nillable values are formatted like this in JSON: "@xsi.nil"
Anyway, thanks for your help,
Anthony
@Produces({"application/json"})
@Consumes({"application/json"})
@Provider
public class ExtendedJSONProvider extends JSONProvider {
public ExtendedJSONProvider() {
setIgnoreNamespaces(true);
final Map<String, String> namespaces = new HashMap<String, String>();
namespaces.put("http://www.w3.org/2001/XMLSchema-instance", "xsi");
setNamespaceMap(namespaces);
}
}

Hi,
I got confused a bit, as you did say

>>>>>> class com.test.ExtendedJSONProvider
So the problem is, that for whatever reasons, a custom provider is not
recognized when it's registered from Application.
Can you please try one of the following:
- try returning com.test.ExtendedJSONProvider.class from
Application.getClasses() but not from Application.getSingletons(); or
the other way around. I can see that either approach is being tested on
the trunk but I'm not 100% sure that that works in 2.3.3 properly
- instead of using Application - try jaxrs.serviceClasses and
jaxrs.providers init parameters - this is a temp step which may help to
isolate the problem which may be to do with @Provider being still not
visible.
- finally - create a simple bundle that can help demonstrating that the
custom provider is not picked up - and please sent to me
thanks, Sergey

Re: CXF 2.3.3 - JSON output - java.lang.IllegalStateException: Invalid
JSON namespace
Posted by Sergey Beryozkin <sb...@gmail.com>.
Hi,
I got confused a bit, as you did say
>>>>>> In the stack trace, I see that JSONProvider is still used... Not

>>>>>> class com.test.ExtendedJSONProvider
So the problem is, that for whatever reasons, a custom provider is not
recognized when it's registered from Application.
Can you please try one of the following:
- try returning com.test.ExtendedJSONProvider.class from
Application.getClasses() but not from Application.getSingletons(); or
the other way around. I can see that either approach is being tested on
the trunk but I'm not 100% sure that that works in 2.3.3 properly
- instead of using Application - try jaxrs.serviceClasses and
jaxrs.providers init parameters - this is a temp step which may help to
isolate the problem which may be to do with @Provider being still not
visible.
- finally - create a simple bundle that can help demonstrating that the
custom provider is not picked up - and please sent to me
thanks, Sergey

Re: CXF 2.3.3 - JSON output - java.lang.IllegalStateException: Invalid
JSON namespace
Posted by Sergey Beryozkin <sb...@gmail.com>.
Hmm...
Sorry, can you please double-check that ExtendedJSONProvider does not
feature anyware in a stack trace ?
I'll add a test on my own a bit later on, I have few tests where
customized JAXB and JSON providers are used (these are effectively
overriding default ones),
Will get back to you asap - may be Monday
Thanks, Sergey

RE: CXF 2.3.3 - JSON output - java.lang.IllegalStateException:
Invalid JSON namespace
Posted by "Muller, Anthony" <an...@sap.com>.
Yep, classes are bundlized and deployed in an osgi environment.
And yes, I imported "javax.ws.rs.ext". As I said, my provider is well instantiated but JSONProvider seems to have an higher priority.
Regards,
Anthony

Hi
I've checked that the code in CXF 2.3.3, CXF 2.4.2 and 2.5.0 that deals
with getting providers from Applications is identical and I have a test
where exception mappers are registered from CXFNonSpringJaxrsServlet and
Application.
I'm wondering if it is an OSGI issue ? Do you have javax.ws.rs.ext
imported ?

RE: CXF 2.3.3 - JSON output - java.lang.IllegalStateException:
Invalid JSON namespace
Posted by "Muller, Anthony" <an...@sap.com>.
Yes, it's what I did. Do you see something wrong?
import javax.ws.rs.Consumes;
import javax.ws.rs.Produces;
import javax.ws.rs.ext.Provider;
import org.apache.cxf.jaxrs.provider.JSONProvider;
@Produces({"application/json"})
@Consumes({"application/json"})
@Provider
public class ExtendedJSONProvider extends JSONProvider {
public ExtendedJSONProvider() {
setIgnoreNamespaces(true);
}
}

Hi, yea it does, but as I said CXF (CXFNonSpringJaxrsServlet) does not
check superclasses for @Provider which will need to be fixed, so for now
please add another @Provider to your custom provider and that will do -

RE: CXF 2.3.3 - JSON output - java.lang.IllegalStateException:

Posted by "Muller, Anthony" <an...@sap.com>.
Hi Sergey,
Are you sure that "org.apache.cxf.jaxrs.provider.JSONProvider" doesn't have the @Provider annotation?
I found it in "cxf-2.3.3.jar" yet :-/

Hi Anthony
How do you register it, using jaxrs.providers parameter ?
A custom provider should be preferred to a default one.
That warning suggests that you probably use a jaxrs.serviceClasses
parameter ?
Or do use register it from the Application implementation ? In that case
this custom provider needs to have a JAX-RS @Provider annotation,
for it to be distinguished from other singletons. JSONProvider does have
it - but in 2.3.3 no checks are made on superclasses - that will need to
be improved in CXF
Let me know please if that works
Cheers, Sergey.

RE: CXF 2.3.3 - JSON output - java.lang.IllegalStateException:
Invalid JSON namespace
Posted by "Muller, Anthony" <an...@sap.com>.
Hey Sergey,
I'm trying to follow your advice and I inherited from JSONProvider class and just set "ignoreNamespace" to true.
At the beginning, I didn't inherit from JSONProvider, but only instantiated this class, set the "ignoreNamespace" property and add it as a provider: however I get an exception because this provider was already registered (by CXF itself I guess).
SO, I add the provider bellow, but I still have the same exception about namespace :(
In the stack trace, I see that JSONProvider is still used... Not my new instance... I guess CXF takes the first provider which is able to handle application/json MIME type?
Moreover, I see this warning in log:
org.apache.cxf.jaxrs.utils.ResourceUtils checkMethodDispatcher
ATTENTION: No resource methods have been found for resource class com.test.ExtendedJSONProvider
The code of the inherited JSONProvider.
import javax.ws.rs.Consumes;
import javax.ws.rs.Produces;
import javax.ws.rs.ext.Provider;
import org.apache.cxf.jaxrs.provider.JSONProvider;
@Produces({"application/json"})
@Consumes({"application/json"})
@Provider
public class ExtendedJSONProvider extends JSONProvider {
public ExtendedJSONProvider() {
setIgnoreNamespaces(true);
}
}
Thanks for help!
Cheers,
Anthony

Hi
The default Jettison provider expects a namespace-to-prefix map set up.
If you don't realy need the prefixes on the receiving end then the
simplest option is to configure JSONProvider with an "ignoreNamespaces"
property, otherwise you'd need to provide a map, here is more info:
http://cxf.apache.org/docs/jax-rs-data-bindings.html#JAX-RSDataBindings-ConfiguringJSONprovider
The thing is how to configure it given that you are using
CXFNonSpringJAXRSServlet.
One option is to extend JSONProvider and only set "ignoreNamespace" or
"namespaceMap" property as needed on the superclass. And register it
with the servlet using a jaxrs.providers parameter.
Another option is try registering Jackson.
I should probably do some enhancement for users be able to set simple
properties on providers registered from web.xml...
Cheers, Sergey

Re: CXF 2.3.3 - JSON output - java.lang.IllegalStateException: Invalid
JSON namespace
Posted by Sergey Beryozkin <sb...@gmail.com>.
Hi
The default Jettison provider expects a namespace-to-prefix map set up.
If you don't realy need the prefixes on the receiving end then the
simplest option is to configure JSONProvider with an "ignoreNamespaces"
property, otherwise you'd need to provide a map, here is more info:
http://cxf.apache.org/docs/jax-rs-data-bindings.html#JAX-RSDataBindings-ConfiguringJSONprovider
The thing is how to configure it given that you are using
CXFNonSpringJAXRSServlet.
One option is to extend JSONProvider and only set "ignoreNamespace" or
"namespaceMap" property as needed on the superclass. And register it
with the servlet using a jaxrs.providers parameter.
Another option is try registering Jackson.
I should probably do some enhancement for users be able to set simple
properties on providers registered from web.xml...
Cheers, Sergey

CXF 2.3.3 - JSON output - java.lang.IllegalStateException: Invalid
JSON namespace
Posted by "Muller, Anthony" <an...@sap.com>.
Hello,
I have an issue when I try to get a JSON output, using a JAXB object, of my REST webservice. (XML output is ok.)
My webservice is running without using Spring.
Can you help me? I don't know how to fix it despite browsing many websites from Google.
Cheers,
Anthony

For some reason, I removed the .accept line, built, it didn't work, put
it back in, built, and it worked. I have absolutely no idea what was
different. There must be ghosts in my machine...

Something is interfering, the above code looks fine - I updated one of
the existing tests (client part only) and did not get this exception.
I can see the Message.properties resource 'losing' a content-type value
which was passed to it during the exception handling, needs to be fixed,
but I think something else is interefing.
By the way, default JSONProvider does not handle Strings...
If you can get CXF source and put a breakpoint in
MulipartProvider.isWriteable then it would provide an answer -
alternatively please create a test project and attach it to JIRA...

Something is interfering, the above code looks fine - I updated one of
the existing tests (client part only) and did not get this exception.
I can see the Message.properties resource 'losing' a content-type value
which was passed to it during the exception handling, needs to be fixed,
but I think something else is interefing.
By the way, default JSONProvider does not handle Strings...
If you can get CXF source and put a breakpoint in
MulipartProvider.isWriteable then it would provide an answer -
alternatively please create a test project and attach it to JIRA...
