Errore Glassfish durante la produzione di JSON

Question

Ho sviluppato un'app per Android e ora sto iniziando con il suo DB esterno e il suo server, la comunicazione viene eseguita dai servizi web RESTful.

Questa applicazione Android produce e consuma solo informazioni in JSON, quindi nelle facciate dei miei servizi Web voglio solo cancellare qualsiasi riferimento a XML nei metodi CRUD (generato automaticamente da NetBeans).

Voglio dire, da questo:

@GET 
@Override 
@Produces({MediaType.APPLICATION_XML, MediaType.APPLICATION_JSON}) 
public List<Counselor> findAll() { 
    return super.findAll(); 
} 

Per questo (senza il MediaType.APPLICATION_XML):

@GET 
@Override 
@Produces(MediaType.APPLICATION_JSON) 
public List<Counselor> findAll() { 
    return super.findAll(); 
} 

Il fatto è che quando ho distribuire questi cambiamenti nel mio GlassFish Server (4.1. 1) e faccio alcuni test con il mio browser (voglio solo vedere i miei dati DB) Ottengo un errore con questo stacktrace:

Qualche idea su questo?

Spero di spiegarmi ... grazie in anticipo !!

Answer 1

Si tratta di un bug in Glassfish 4.1.1 https://java.net/jira/browse/JERSEY-2888

sono stato in grado di risolvere il problema in un modo sporco:

In GlassFish/modules/org.eclipse.persistence.moxy.jar fissare META-INF /MANIFEST.MF basta aggiungere quanto segue per Import-Package:

,org.xml.sax.helpers,javax.xml.parsers;resolution:=optional,javax.naming;resolution:=optional 

in modo che appaia come dopo:

e riavviare GF

btw: si può facilmente modificare i vasetti IN con

emacs org.eclipse.persistence.moxy.jar 

Answer 2

risposta di Jack è veramente utile.
Individua il problema ed è stato utile in assenza di patch.

Ma suggerisco invece di modificare il vaso, dal momento che il bug è stato corretto in 2.6.1, per scaricarlo a: http://book2s.com/java/jar/o/org-eclipse-persistence-moxy/download-org.eclipse.persistence.moxy-2.6.1.html e sostituirlo.
Non dimenticare di chiudere e riaprire l'IDE.
