CXF REST problems
Hi there,
I've been looking through the user group and I haven't been able to find an
answer to my problem so I thought I'd send a post and see if anyone can help
me.
I downloaded the 20080228 and the 20080303 snapshots. What I describe below
are problems that I have found in both.
First problem that I've noticed is that I can't find the @UriTemplate
annotation. It's not in the jsr311-api-0.5.jar file where all of the other
JSR annotations can be found. So, I had a look at the JSR spec, and the
@Path annotation seemed appropriate so I used that instead. Is that correct?
Second problem is that I implemented a service using the @Path annotation
and I'm getting a null pointer exception as described below. I am using
spring configuration, so here's my spring config file:
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:jaxrs="http://cxf.apache.org/jaxrs"
xmlns:cxf="http://cxf.apache.org/core"
xsi:schemaLocation="
http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://cxf.apache.org/core http://cxf.apache.org/schemas/core.xsd
http://cxf.apache.org/bindings/soap
http://cxf.apache.org/schemas/configuration/soap.xsd

<import resource="classpath:META-INF/cxf/cxf-servlet.xml" />
<jaxrs:server id="registryEndpoint" address="/">
<jaxrs:serviceBeans>
<ref bean="emitterResource"/>
</jaxrs:serviceBeans>
</jaxrs:server>
</beans>
Here's the resource file:
@Path("/emitterResource")
public class EmitterResource {
@Path("/getEmitters")
public Collection<Emitter> getEmitters() {
return emitterDAO.getAllEmitters();
}
@Path("/emitters/{emitterId}")
public Emitter getEmitter(@QueryParam("emitterId") int id) {
//public Emitter getEmitter(@WebParam(name = "emitterId") int id) {
LOG.debug("looking for emitter id " + id);
return emitterDAO.get(id);
}
@Path("/emitters")
public void addEmitter(@QueryParam("emitter")Emitter emitter) {
LOG.warn("Adding an emitter");
LOG.warn("ID is " + emitter.getId());
LOG.warn("Name is " + emitter.getName());
emitterDAO.save(emitter);
}
When I try to add @HttpMethod annotations above the @Path annotations I get
the error "The annotation @HttpMethod is disallowed for this location"
The Emitter class is just a POJO with an Id and a Name.
Here's a snippet of my client code (I'm using apache commons HttpClient) :
Emitter e = new Emitter();
e.setId(12345);
e.setName("Test Name");
PostMethod post = new
PostMethod("http://localhost:8080/emitterResource/emitters");
StringWriter stringWriter = new StringWriter();
jaxbMarshaller.marshal(registryObject, stringWriter);
StringRequestEntity requestEntity = new
StringRequestEntity(stringWriter.toString(), "text/xml", "ISO-8859-1");
post.setRequestEntity(requestEntity);
HttpClient httpClient = new HttpClient();
int result = httpClient.executeMethod(post);
System.out.println("Response code " + result);
System.out.println(post.getResponseBodyAsString());
post.releaseConnection();
I'm deploying the server in tomcat 5.5 successfully (no errors), but when I
run the client, I'm getting the following exception:

Hey hey!
Removing the @UriParam did the trick!
@POST
@Path("/emitters")
public void addEmitter(Emitter emitter) {
}
thanks for the help!

Re: CXF REST problems

Hi,
In this case what happens is that no MessageBodyReader (provider capable of getting the input stream data and turning them into Emitter object) has been found, thus it's a null and it's an application level error. That said, I need to check what the spec says about it, perhaps an exception shouild be raised earlier...
What is an Emmiter class ? Is it annotated with JAXB annotatations such as @XmlRootElement ?
Does GET works for you, that is can you retrieve an individual Emitter from a browser ?
If Emitters are not JAXB-aware then you'd need to register a custom Emitter provider, which would know how to serialize/deserialize them. Alertantive you might want to use JAXP Source and deal with XML locally...
Actually, I've written it all and just realized that your annotations are not correct :
> @POST
> @Path("/emitters/")
> public void addEmitter(@UriParam("emitter")Emitter emitter) {
One can annotate with @UriParam only those parameters which are supposed to be substituted as template variables found in your @Path, for ex :
@PUT
@Path("/emitters/{id}")
public void addEmitter(@UriParam("id") String id, Emitter emitter) {
}
So in your case doing just
@POST
@Path("/emitters")
public void addEmitter(Emitter emitter) {
}
should work fine, provided your Emitter is JAXB-aware :-)
Give it a try please,
Cheers, Sergey

Hi, and thanks for your reply. I have tried your suggestion, I changed the
@QueryParam to @UriParam and now I get a different error. Here's the updated
method:
@POST
@Path("/emitters")
public void addEmitter(@UriParam("emitter")Emitter emitter) {
LOG.warn("Adding an emitter");
LOG.warn("ID is " + emitter.getId()); <----- NullPointerException on
this line
LOG.warn("Name is " + emitter.getName());
emitterDAO.save(emitter);
}
This is the NullPointerException exception:

It's a NumberFormatException there, and it's caused by the fact there's no expected QueryParam in a request.
You need to use @UriParam instead (please note in 0.6 it will be replaced with @PathParam), see below...
> When I try to add @HttpMethod annotations above the @Path annotations I get
> the error "The annotation @HttpMethod is disallowed for this location"
Yes, starrting from 0.5 one can use @HttpMethod to create designators, sucg as @GET/@POST@PUT/@DELETE,
so you may for example create @GetRequest if you think it's better than @GET or create designators for other http methods
Here's the class :
@Path("/emitterResource")
public class EmitterResource {
@GET
@Path("/getEmitters")
public Collection<Emitter> getEmitters() {
return emitterDAO.getAllEmitters();
}
@GET
@Path("/emitters/{emitterId}")
public Emitter getEmitter(@UriParam("emitterId") int id) {
LOG.debug("looking for emitter id " + id);
return emitterDAO.get(id);
}
}
You might want to chnage it like this to minimize a bit the numbner of annotations :
@Path("/emitters")
public class EmitterResource {
@GET
public Collection<Emitter> getEmitters() {
return emitterDAO.getAllEmitters();
}
@GET
@Path("{emitterId}")
public Emitter getEmitter(@UriParam("emitterId") int id) {
LOG.debug("looking for emitter id " + id);
return emitterDAO.get(id);
}
}
Hope it helps
