Hello,
no matter how hard I try I just cannot get TomEE to use Jackson instead of
Johnzon. Want to use Jersey with Jackson
I tried to:
- Set the providers "cxf.jaxrs.providers" in openejb-jar.xml
( log entry: org.apache.openejb.server.rest.RESTService.deployApplication
Registered JAX-RS Configuration: ...)
- Extend Jackson provider as
@Produces(MediaType.APPLICATION_JSON)
@Consumes(MediaType.APPLICATION_JSON)
public class OurJsonProvider
extends com.fasterxml.jackson.jaxrs.json.JacksonJaxbJsonProvider {}
I have pom dependencies:
<dependency>
<groupId>com.fasterxml.jackson.jaxrs</groupId>
<artifactId>jackson-jaxrs-json-provider</artifactId>
<version>2.9.0</version>
</dependency>
<dependency>
<groupId>org.glassfish.jersey.media</groupId>
<artifactId>jersey-media-json-jackson</artifactId>
<version>2.26-b09</version>
</dependency>
etc.
Yet whenever I try to serialize object I get
Caused by: org.hibernate.LazyInitializationException: failed to lazily
initialize a collection of role: ..., could not initialize proxy - no
Session
at
org.hibernate.collection.internal.AbstractPersistentCollection.throwLazyInitializationException(AbstractPersistentCollection.java:582)

org.hibernate.collection.internal.AbstractPersistentCollection.withTemporarySessionIfNeeded(AbstractPersistentCollection.java:201)

org.hibernate.collection.internal.AbstractPersistentCollection.initialize(AbstractPersistentCollection.java:561)

org.hibernate.collection.internal.AbstractPersistentCollection.read(AbstractPersistentCollection.java:132)
at
org.hibernate.collection.internal.PersistentBag.iterator(PersistentBag.java:277)
at
org.apache.*johnzon*.mapper.MappingGeneratorImpl.writeValue(MappingGeneratorImpl.java:315)
and a lot more johnzon stacktracke lines...
Obviously because I have my properties annotated with Jackson and the object
is serialized with Johnzon instead and it's ignoring my annotations.
What am I doing wrong?
Thank you
