[ERROR ] MessageBodyWriter not found for media type=application/xml, type=class XX.XX.XXX, genericType=class is coming , if we remove the #produces annotation in JERSER2 rest service
This error is resolved when I start using #produces annotations, however for my swagger to work, we need to remove this annotation.
Isnt that JERSEY2 should be able to accept it without explicitly mentioning #produces in the endpoint ?
Please advise, any input would be appreciated.

I'm using the latest milestone of spring-cloud-sleuth and I can't seem to get traces emitted through opentracing. I have a Tracer bean defined and spring boot seems to acknowledge that, but no traces are being emitted.
Is there a way to check if spring-cloud-sleuth is aware of the Tracer bean?
update
I did see the merged documentation and have a Tracer instance on the bean, as defined below:
#Bean(name = "tracer")
#Primary
public Tracer lightstepTracer() throws MalformedURLException {
Options opt = lightstepOptionsBuilder.build();
log.info("Instantiating LightStep JRETracer.");
return new JRETracer(opt);
}
I'm not explicitly importing the OpenTracing APIs, because the LightStep tracer pulls that in transitively, but I can try doing that.
I've also explicitly enabled OpenTracing support in my application.yml file.
sleuth:
opentracing:
enabled: true
If you go to the latest snapshot documentation (or milestone) and you search for the word OpenTracing, you would get your answer. It's here https://cloud.spring.io/spring-cloud-sleuth/single/spring-cloud-sleuth.html#_opentracing
Spring Cloud Sleuth is compatible with OpenTracing. If you have OpenTracing on the classpath, we automatically register the OpenTracing Tracer bean. If you wish to disable this, set spring.sleuth.opentracing.enabled to false
So it's enough to just have OpenTracing on the classpath and Sleuth will work out of the box
I want to run Hibernate in OSGi. I have added the standard Hibernate OSGi bundle and a Blueprint implementation, so that Envers gets registered right on startup.
Even without any kind of documentation I found out you have to start Envers, because... I doubt there is a logical reason, it does not work otherwise.
However now, even though Envers was registered in Blueprint, I get the following exception:
org.hibernate.service.UnknownServiceException: Unknown service requested [org.hibernate.envers.boot.internal.EnversService]

The stack trace starts at PersistenceProvider#createEntityManagerFactory in the following snippet:
public class Main {
private EntityManagerFactory entityManagerFactory;
public void startSession(Map<String, Object> config) {
BundleContext context = FrameworkUtil.getBundle(getClass()).getBundleContext();
ServiceReference<PersistenceProvider> serviceReference = context.getServiceReference(PersistenceProvider.class);
PersistenceProvider persistenceProvider = context.getService(serviceReference);
this.entityManagerFactory = persistenceProvider.createEntityManagerFactory("persistenceUnit", config);
context.ungetService(serviceReference);
}
I found this bug, and maybe this issue is fixed in the current version of Hibernate. But since the bundle IDs are broken, I have to use 5.1.
So Envers is registered, but not really. What could be the reason for such a strange error message?
I am currently working on Spring soap server project. I started off with the Getting Started guide from Spring here http://spring.io/guides/gs/producing-web-service/ to build a basic SOAP service.
The default SOAP protocol is SOAP v1.1. Is there a way I could set the protocol to v1.2, possibly via annotations?
I tried #BindingType(javax.xml.ws.soap.SOAPBinding.SOAP12HTTP_BINDING) annotation on the #Endpoint class but it doesnt seem to work.
I also tried #Endpoint(value = SOAPBinding.SOAP12HTTP_BINDING) to set it, but this doesnt work either as seen in the logs on startup

Any help is appreciated.
Thanks!
You are mixing Spring-WS with annotations from JAX-WS (package javax.xml.ws). That won't work. To configure Spring-WS to use SOAP 1.2, add the following bean definition:
#Bean
public SaajSoapMessageFactory messageFactory() {
SaajSoapMessageFactory messageFactory = new SaajSoapMessageFactory();
messageFactory.setSoapVersion(SoapVersion.SOAP_12);
return messageFactory;
}
If the messageFactory Bean is not in the singleton scope, then the afterPropertiesSet() method in the SaajSoapMessageFactory is not called on bean instantation.
The afterPropertiesSet() method sets up an internal message factory. So if your messageFactory bean has its own scope you need to set up the internal message factory like this:
#Bean
#Scope("custom-scope")
public SaajSoapMessageFactory messageFactory() {
SaajSoapMessageFactory messageFactory = new SaajSoapMessageFactory();
messageFactory.messageFactory = MessageFactory.newInstance(SOAPConstants.SOAP_1_2_PROTOCOL);
return messageFactory;
}
The messageFactory() #Bean is a necessary step, but isn't it also fundamental to add
wsdl11Definition.setCreateSoap12Binding(true);
to the service definition, to generate the appropriate soap 1.2 binding?
Anyway, thanks to Andreas Veithen
Although there already are quite some StackOverflow questions, blog entries, etc. on the web, I still cannot figure out a solution to the problem stated below.
Similar to this question (Injecting EJB within JAX-RS resource on JBoss7) I'd like to inject a EJB instance into a JAX-RS class. I tried with JBoss 5, JBoss 7, and WildFly 8. I either get no injection at all (field is null), or the server does not deploy (as soon as I try to combine all sorts of annotations).
Adding #Stateless to the JAX-RS makes the application server know both classes as beans. However, no injection takes place.
Is there a way to inject EJBs into a REST application? What kind of information (in addition to that contained in the question linked to above) could I provide to help?
EDIT: I created a Github project showing code that works (with Glassfish 4.0) and does not work (with JBoss 5).
https://github.com/C-Otto/beantest
Commit 4bf2f3d23f49d106a435f068ed9b30701bbedc9d works using Glassfish
4.0.
Commit 50d137674e55e1ceb512fe0029b9555ff7c2ec21 uses Jersey 1.8, which does not work.
Commit 86004b7fb6263d66bda7dd302f2d2a714ff3b939
uses Jersey 2.6, which also does not work.
EDIT2:
Running the Code which I tried on JBoss 5 on Glassfish 4.0 gives:
Exception while loading the app : CDI deployment failure:WELD-001408 Unsatisfied dependencies for type [Ref<ContainerRequest>] with qualifiers [#Default] at injection point [[BackedAnnotatedParameter] Parameter 1 of [BackedAnnotatedConstructor] #Inject org.glassfish.jersey.server.internal.routing.UriRoutingContext(Ref<ContainerRequest>, ProcessingProviders)]

EDIT3: The crucial information might be that I'd like a solution that works on JBoss 5
If you don't want to make your JAX-RS resource an EJB too (#Stateless) and then use #EJB or #Resource to inject it, you can always go with JNDI lookup (I tend to write a "ServiceLocator" class that gets a service via its class.
A nice resource to read about the topic:
https://docs.jboss.org/author/display/AS71/Remote+EJB+invocations+via+JNDI+-+EJB+client+API+or+remote-naming+project
A sample code:
try {
// 1. Retreive the Home Interface using a JNDI Lookup
// Retrieve the initial context for JNDI. // No properties needed when local
Context context = new InitialContext();
// Retrieve the home interface using a JNDI lookup using
// the java:comp/env bean environment variable // specified in web.xml
helloHome = (HelloLocalHome) context.lookup("java:comp/env/ejb/HelloBean");
//2. Narrow the returned object to be an HelloHome object. // Since the client is local, cast it to the correct object type.
//3. Create the local Hello bean instance, return the reference
hello = (HelloLocal)helloHome.create();
} catch(NamingException e) {
} catch(CreateException e) {
}
This is not "injecting" per-se, but you don't use "new" as-well, and you let the application server give you an instance which is managed.
I hope this was useful and I'm not telling you something you already know!
EDIT:
This is an excellent example: https://docs.jboss.org/author/display/AS72/EJB+invocations+from+a+remote+client+using+JNDI
EDIT 2:
As you stated in your comment, you'd like to inject it via annotations.
If the JNDI lookup is currently working for you without problems, and
If you're using Java EE 6+ (which I'm guessing you are), you can do the following:
#EJB(lookup = "jndi-lookup-string-here")
private RemoteInterface bean;
I am trying out simple JPA example on TomEE 4.0.0 and I am not able to get PersistenceContextType.EXTENDED working
If I make my session bean Stateless and leave PersistenceContextType then it works fine
#PersistenceContext(unitName = "xxx" )
private EntityManager entityManager;
If I keep my session bean as Stateless and then try to use this
#PersistenceContext(unitName = "xxx", type = PersistenceContextType.EXTENDED))
private EntityManager entityManager;
it gives me an error while deploying, which is perfectly fine and in line with expectation.
However now when I make my bean as #Stateful, then also it gives me an error
Managed ejbs are not capable of using EntityManagers with EXTENTED persistence. Convert your bean to a Stateful ejb or update the "java:comp/env/com.testwebservice.TestJPAService/entityManager" PersistenceContext reference to PersistenceContextType.TRANSACTION.
Can some one please help, I am really confused for this
#Stateful EXTENDED persistence contexts are tested in numerous ways in the TomEE build and also in the Java EE TCK.
Likely this is something else completely. We do our best to warn you when you make obvious mistakes as you note with the incorrect combination of #Stateless with PersistenceContextType.EXTENDED
Looking at the JNDI name which contains com.testwebservice.TestJPAService and given the fact it was #Stateless before it was changed to #Stateful, my guess is that this bean is also an #WebService which is illegal. #Stateful beans cannot be #WebService beans. Without a proper check to prevent this mistake, my guess is that the bean is actually being deployed twice; once as a #Stateful bean and once as an pojo #WebService. The pojo web service is the one causing the error.
In case that is the error, I've filed a JIRA for us to explicitly check that condition.
