Hi Sergey, thanks for the awesome (and quick response). What you suggested
worked great. I overrode this method:
@Override
protected boolean isSupported(Class<?> type, Type genericType, Annotation[]
annotations) {
if(String.class.equals(type)) {
return false;
} else {
return super.isSupported(type, genericType, annotations);
}
}
And I was able to get at the body of the request as a String using the
following service method:
@POST
@Path("/execute/{scriptName}")
@Consumes({MediaType.APPLICATION_XML})
public Response executeDocumentPost(
final @PathParam("scriptName") String scriptName,
final String body {
Now, I've modified it slightly, and it is not working. Instead of
Content-Type: application/xml, I want to accept all content-types, and I want
the InputStream instead of the String body. I also want to inject the context
headers and uri info, so the new service method is like this:
@POST
@Path("/execute/{scriptName}")
@Consumes({MediaType.WILDCARD})
public Response executeDocumentPost(
final @PathParam("scriptName") String scriptName,
final InputStream body,
final @Context HttpHeaders httpHeaders,
final @Context UriInfo uri) {
This doesn't work, however. In the isSupported method, I am passed a
MultiValuedMap as the type, so I modified the behavior slightly like this:
Where does MultivaluedMap is coming from ? What about InputStream ?
if(String.class.equals(type) || type.isAssignableFrom(InputStream.class) ||
type.isAssignableFrom(MultivaluedMap.class) ) {
return false;
} else {
return super.isSupported(type, genericType, annotations);
}
Now, my code returns false here, but it still gives me an error => No mapping
found for MultiValuedMap input.
Now, if I change the @Consumes annotation to explicitly accept
MediaType.APPLICATION_XML, it works as expected:
@Consumes({MediaType.WILDCARD, MediaType.APPLICATION_XML})
But this only works if I set the Content-Type: application/xml. If I want to
upload JSON, for example, it won't work. Why doesn't the MediaType.WILDCARD
seem to work here for other content types?
We need to figure why are you seeing MultivaluedMap, do you have on some
other method ?
Cheers, Sergey
Thanks in advance,
Davis

Subject: Re: Question on Providers
Hi

Hi, I have a question on providers. The code base I'm working on uses a
subclass of AegisElementProvider. I'm trying to add a new method to a service
class where this provider is in play. I want a very simple resource that
allows one to POST any free-form XML document...like this:
@Path("/foo")
@Consumes(MediaType.APPLICATION.XML)
public Response postXml(String body) {
...
}
...and call it like this from curl:
curl -d "<xml>foo</xml>" -H "Content-Type: application/xml" -X POST
"http://host/path/foo"
Unfortunately, the same service has another method on it that accepts
a JAXB/typed XML document with namespaces, etc. When I post to my
method above, the Provider first gets the request, and tries to
marshall it into some Java type, and the request fails -- seems it
expecting a specific xsi:type
In this case it is still an AegisElementProvider that picks up the payload
because at the moment it supports all the types, even primitive ones such as
String (I guess Aegis will wrap/unwrap them somehow).
Does that other method you are referring to (or some other method in the
service class) rely on Aegis DataBinding ? Or is it all JAXB ? AFAIK Aegis can
handle JAXB annotations but if it is just JAXB then depending on JAXBProvider
can be better in which case you'll get a String provider copying the input xml
as String.
If you do need to use AegisElementProvider then the simplest thing to do is to
override isSupported method in your subclass and return false for String.class,
true - for others and that should do it
HTH, Sergey
WARN 2011-12-01 01:49:46,640 [TypeUtil] xsi:type was not specified
for top-level element xml WARN 2011-12-01 01:49:46,648
[WebApplicationExceptionMapper] WebApplicationException has been caught : No
mapping found for XML input.
So, my question is this: is there some way to easily bypass this Provider for
this method, so I can post any content I want as application/xml and have it
just converted to a String -- bypassing the whole JAXB process altogether?
