How to use CXF and JSON
Hello,
I'm very new to building RESTful webservices using apache cxf and I
currently have a small sample that returns a javax.ws.rs.core.Response in
xml format using the @ProduceMime("application/xml"). My question is how do
I return a javax.ws.rs.core.Response in JSON format? I've tried using
@ProduceMime("text/json"), @ProduceMime("application/json"). I'm using JAXB
to convert the object to xml and then rebuilding the response, but I'm not
sure how to rebuild the response when I return json. Is this possible with
CXF?
Thanks,
Colin

Hi Colin
Just replace get() with say post(objectInstance, CustomObject.class) or
just post(objectInstance). There's also a method called invoke() which
accepts an HTTP method name as the 1st parameter
Cheers, Sergey

Sergey,
how would you mimic a POST request with the WebClient? It works fine
for a
GET request. I need to post an entire object to the web service method
so I
would prefer using a POST. Any suggestions or guidelines for this?
Thanks,
Colin

Re: How to use CXF and JSON
Posted by Sergey Beryozkin <sb...@progress.com>.
Perhaps you can use a CXF client api instead ?
try
MyObject object = WebClient.create(address).accept("application/xml,application/json").get(MyObject.class)

RE: How to use CXF and JSON
Posted by cgswtsu78 <cg...@proofpoint.com>.
David or Sergey,
I guess back to my original question....except this should be a bit more
clear.
I'm using apache's httpclient in order to process POST and GET requests to
my REST service methods. These POST and GET requests are being executed
from a JSF managed bean in order to retrieve an object and then perform
operations on that object before displaying it in a xhtml page. While using
xml I'm able to return the HttpResponse from the service method and use the
HttpResponse.getBodyAsString() along with JAXB in order to convert the xml
string to an object.
For JSON, what would be the best way to return the JSON string and then
convert that to an object so that I can return that to the consumer of the
service method (JSF managed bean) in order for it to perform operations on
it?

it?

Then don't do that. :)
Use SoapUI, or some other tool that knows JAX-RS. It can even read the
WADL specification and generate the tests for you.

Re: How to use CXF and JSON
Posted by cgswtsu78 <cg...@proofpoint.com>.
That did work, but it required me to save the json string as a file. When
opening it in notepad it has the correct object representation. How can I
display the json string in the browser? Do I have to setup something prior
to making the request to the service method? Currently, I'm just executing
a GET request by pasting in a url in IE.

Hi
You probably just don't need to do it all, just do
@Produces(application/xml, application/json)
@GET
public SomeConcreteObjectType get(...) {

Re: How to use CXF and JSON
Posted by cgswtsu78 <cg...@proofpoint.com>.
Hi Sergey,
I don't quite understand the proper implementation for using CXF and JSON.
I have the xml implementation working, see below. Can you guide me on doing
the same basic function but returning JSON? I know I need to change the
@Produces to "application/json", but what setup do I need to do in order to
return the json string representing the Object "o" to the browser or
consumer of the service? Thanks for the help!
xml version:
import javax.ws.rs.GET;
import javax.ws.rs.POST;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.Response;
public class XMLExample{
@GET
@Path("/getTopSpamSender")
@Produces("application/xml")
public Response retrieveTopSpamSenderData() throws Exception {
Response httpresp;
String httpbody;
httpresp=null;
Object o = topSpamSenderService.getTopSpamSender(null);
if (o != null)
{
httpbody = JaxbUtils.ObjToXmlStr(o, false);
httpresp = setupResponse(Response.ok(httpbody)).build();
}
else
httpresp = setupResponse(Response.noContent()).build();
return httpresp;
}
}
public static String ObjToXmlStr(Object obj, boolean includeXmlVerHdr)
{
try
{
StringWriter sw = new StringWriter();
JAXBContext jaxbctx = JAXBContext.newInstance(obj.getClass());
Marshaller marshaller = jaxbctx.createMarshaller();
marshaller.setProperty(Marshaller.JAXB_ENCODING, "UTF-8");
marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);
marshaller.marshal(obj, sw);
if (!includeXmlVerHdr)
{
String str = sw.toString();
int beginIndex = str.toString().indexOf(">");
return str.substring(beginIndex + 2);
}
return sw.toString();
} catch (Exception e)
{
log.error("Failed to create XML from Object", e);
}
return null;
}

Re: How to use CXF and JSON

Thanks David...
Looks like the problem has to do with that fact that an Object instance is being returned....
The method.getReturnType() is used when searching for providers...

I believe if you Google for "JAXRSOutInterceptor

When I do the below I get the below exception. EnvFromHourlyWrapper is my

this.envs = envs;

RE: How to use CXF and JSON
Posted by cgswtsu78 <cg...@proofpoint.com>.
So the below will return the json representation of the Object o? No other
setup is needed? Thanks for the quick responses!
@GET
@Path("/topspamsenderjson")
@Produces("application/json")
public Object getTopSpamSenderData() throws Exception
{
Object o = topSpamSenderService.getTopSpamSender();
return o;
}

I wondered what you were talking about in your previous note.
Typically, you don't do anything to format the response except for
returning the object from the method. The container does the work of
formatting the response in either XML or JSON. Most of this code you've
written wasn't necessary. You can modify the formatting of the response
with "@Xml..." annotations (which also can affect the JSON output), but
mostly you just let the container do the work.

RE: How to use CXF and JSON
Posted by cgswtsu78 <cg...@proofpoint.com>.
Ok, I've made that switch, but I'm still confused as how I need to setup the
javax.ws.rs.core.Response. How would I take an Object and convert it into a
json string? Below is the xml sample I created, any suggestions on
converting this to a json implementation would be greatly appreciated.
import javax.ws.rs.GET;
import javax.ws.rs.POST;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.Response;
@Path("/chartsvcs/")
public class sample{
@POST
@Path("/topspamsender")
@Produces({"application/xml", "application/json"})
public Response getTopSpamSenderData(ChartSpecification chartSpec) throws
Exception {
Response httpresp;
String httpbody;
httpresp=null;
Object o = topSpamSenderService.getTopSpamSender(chartSpec); //just
retrieves an object to be returned to the consumer
if (o != null)
{
httpbody = ObjToXmlStr(o, false);
httpresp = setupResponse(Response.ok(httpbody)).build();
}
else
{
httpresp = setupResponse(Response.noContent()).build();
}
return httpresp;
}
/**
* Converts a Pojo to JAXB string
* @param obj
* @param includeXmlVerHdr Indicates if returned string should be have the
XML version tag
* @return JAXB representation of the object
*/
private static String ObjToXmlStr(Object obj, boolean includeXmlVerHdr)
{
try
{
StringWriter sw = new StringWriter();
JAXBContext jaxbctx = JAXBContext.newInstance(obj.getClass());
Marshaller marshaller = jaxbctx.createMarshaller();
marshaller.setProperty(Marshaller.JAXB_ENCODING, "UTF-8");
marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);
marshaller.marshal(obj, sw);
if (!includeXmlVerHdr)
{
String str = sw.toString();
int beginIndex = str.toString().indexOf(">");
return str.substring(beginIndex + 2);
}
return sw.toString();
} catch (Exception e)
{
log.error("Failed to create XML from Object", e);
}
return null;
}
}

The "old" "@ProduceMime" annotation has been replaced with "@Produces".
The following will make a method produce either XML or JSON, depending
on the Accept header value:
@Produces({"application/xml", "application/json"})
