glassfish - Why is POJO JSON mapping feature (MOXy) in Jersey not working in this simple example? -

i'm trying simple pojo mapping work in fresh application. i'm next several online examples, nil works.

severe: messagebodywriter not found media type=application/json...

from glassfish (4.0)

my app startup right out of bailiwick of jersey quickstart guide:

@applicationpath("/") public class app extends resourceconfig { public app() { final moxyjsonconfig moxyjsonconfig = new moxyjsonconfig(); map<string, string> namespaceprefixmapper = new hashmap<string, string>(1); namespaceprefixmapper.put("http://www.w3.org/2001/xmlschema-instance", "xsi"); moxyjsonconfig.setnamespaceprefixmapper(namespaceprefixmapper).setnamespaceseparator(':'); register(moxyjsonconfig); }

}

and resource class right out of guide:

@path("/") public class pojotestservice { @get @produces(mediatype.application_json) homecoming new pojo(); } }

the pojo well, pojo! i've tried , without @xmlrootelement, since found contradictory info on if should included or not...

my pom.xml:

web.xml:

<?xml version="1.0" encoding="utf-8"?> <!-- web.xml file not required when using servlet 3.0 container, see implementation details http://jersey.java.net/nonav/documentation/latest/jax-rs.html --> <web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/xmlschema-instance" xsi:schemalocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"> <servlet> <servlet-name>jersey web application</servlet-name> <servlet-class>org.glassfish.jersey.servlet.servletcontainer</servlet-class> <init-param> <param-name>jersey.config.server.provider.packages</param-name> <param-value>com.mycom.server.package</param-value> </init-param> <init-param> <param-name>com.sun.jersey.api.json.pojomappingfeature</param-name> <param-value>true</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>jersey web application</servlet-name> <url-pattern>/webapi/*</url-pattern> </servlet-mapping>

what have forgotten configure?

looks you're using config-keys bailiwick of jersey 1.x, starting "com.sun.jersey...". in version 2.x of bailiwick of jersey has changed, can perhaps see in key:

jersey.config.server.provider.packages

i've got running creating empty application class in top bundle of webservice classes:

package path.to.your.ws; import javax.ws.rs.core.application; public class wsapp extends application { }

in web.xml you've point application class , other classes in bundle , below registred.

<servlet> <servlet-name>rest-service</servlet-name> <servlet-class>org.glassfish.jersey.servlet.servletcontainer</servlet-class> <init-param> <param-name>javax.ws.rs.application</param-name> <param-value>path.to.your.ws.wsapp</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>rest-service</servlet-name> <url-pattern>/rest/*</url-pattern> </servlet-mapping>

instead moxy can seek next bailiwick of jersey media module (i have not compared them):

<dependency> <groupid>org.glassfish.jersey.media</groupid> <artifactid>jersey-media-json-jackson</artifactid> <version>2.13</version> </dependency>
