JAX-WS & JSR 330 (Spring) - cannot inject dependency - dependency-injection

Question

I cannot seem to inject a simple bean into my #WebService. With Spring on the classpath and javax.inject dependencies defined, I created a simple JAX-WS webservice with some underlying interface-driven DAOs etc:
#Named
#WebService(name = "NoteStorage", serviceName = "NoteStorageWS")
public class NoteStorageWS implements NoteStore {
private static final Log l = LogFactory.getLog(NoteStorageWS.class);
#Named("NoteDAO")
#Inject
private NoteDAO noteDAO;
public NoteStorageWS() {
super();
}
#Override
#WebMethod
public StorageState takeNote(String note) {
try {
l.info(format("Service received message: '%s'", note));
Note n = new Note();
n.setContent(note);
noteDAO.store(n);
} catch (Exception e) {
l.error(e);
return StorageState.FAILURE;
}
return StorageState.SUCCESS;
}
#WebMethod(exclude = true)
public void setNoteDAO(NoteDAO noteDAO) {
this.noteDAO = noteDAO;
}
}
NoteDAOhas just implementation: FlatFileNoteDAO which is defined as follows:
#Named("NoteDAO")
public class FlatFileNoteDAO implements NoteDAO {
private static final Log l = LogFactory.getLog(FlatFileNoteDAO.class);
#Override
public void store(Note n) {
if (n == null) {
throw new IllegalArgumentException("Note was null");
}
try {
l.info(format("Storing note '%s'", n));
FileWriter fileWriter = new FileWriter(new File("Note"));
fileWriter.write(format("%s\n", n.getContent()));
fileWriter.close();
} catch (IOException e) {
throw new DataAccessException(e);
}
}
}
My web.xml says:
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="3.0" xmlns="http://java.sun.com/xml/ns/javaee"

</resource-env-ref>
</web-app>
I deploy the application to Glassfish by pointing it to the target/note-ws/ directory and execute the simple takeNote method via the ?Tester page.
Upon submission of the tester form I get a NullPointerException at the line noteDAO.store(n);, presumably because noteDAO wasn't injected.
I can confirm that Spring has been invoked by the logs from glassfish on context initialisation (the Java EE context):

which says my beans are defined: noteStorageWS, NoteDAO and so-on.
Any ideas?
Edit
to clarify, I'm using Spring to provide JSR 330 -- dependency injection -- functionality.

Answer 1

I never got this solved, so I ended up removing the DI-features as the codebase was small and relied on manual dependency resolution - plain old new IFaceImpl(); for now.

Answer 2

JAX-WS and Guice require a specific integration via #GuiceManaged annotation. More info here.

Answer 3

Move the business logic to a separate bean and annotate it with #Configurable so that Spring can handle the lifecycle of the bean. Now use that bean in NoteStorageWS
#Configurable
public class NoteStorageUtil{
#Named("NoteDAO")
#Inject
private NoteDAO noteDAO;
public StorageState takeNote(String note) {
try {
l.info(format("Service received message: '%s'", note));
Note n = new Note();
n.setContent(note);
noteDAO.store(n);
} catch (Exception e) {
l.error(e);
return StorageState.FAILURE;
}
return StorageState.SUCCESS;
}
}
#WebService(name = "NoteStorage", serviceName = "NoteStorageWS")
public class NoteStorageWS implements NoteStore {
public StorageState takeNote(String note) {
return new NoteStorageUtil().takeNote(note)
}
}
Or please check if your end point configuration is proper, so that the web service end point is a spring-managed bean also.
Eg:-
<bean id="hello" class="demo.spring.service.HelloWorldImpl" />
<jaxws:endpoint id="helloWorld" implementor="#hello" address="/HelloWorld" />
