package-info.java

@XmlSchema( 
    namespace = "http://testv80.elsyarres.net/service.asmx", 
    elementFormDefault = XmlNsForm.QUALIFIED) 
package com.myProject.wegolo 

import javax.xml.bind.annotation.XmlNsForm; 
import javax.xml.bind.annotation.XmlSchema; 

Codice

 ... 
     SOAPMessage sm = response; 
     ByteArrayOutputStream out = new ByteArrayOutputStream(); 
     sm.writeTo(out); 

     this.results = (SearchFlightsResponse) JAXB.unmarshal(sm.toString(), SearchFlightsResponse.class); 

Answer 1

La riga seguente è quello che si sta causando il problema:

JAXB.unmarshal(sm.toString(), SearchFlightsResponse.class); 

Il risultato di sm.toString() sta per essere qualcosa di simile a quanto segue e non un String rappresentazione del XML.

com.sun.xml.internal.messaging.saaj.soap.ver1_2.Message1_2Impl@693f23a2 

Quello che state facendo ora è l'equivalente di fare la seguente:

import javax.xml.bind.JAXB; 

public class Demo { 

    public static void main(String[] args) throws Exception { 
     JAXB.unmarshal("com.sun.xml.internal.messaging.saaj.soap.ver1_2.Message1_2Impl@693f23a2", Foo.class); 
    } 
} 

che restituirà la seguente eccezione:

Exception in thread "main" java.lang.IllegalArgumentException: URI is not absolute 
    at java.net.URI.toURL(URI.java:1095) 
    at javax.xml.bind.JAXB.toSource(JAXB.java:291) 
    at javax.xml.bind.JAXB.unmarshal(JAXB.java:205) 
    at forum23652823.Demo.main(Demo.java:8) 

Nota

Il String parametro nelIl metodoè il percorso dell'XML e non l'XML stesso. Questo è il motivo per cui l'eccezione si lamenta di un URI.

Answer 2

La risposta XML che si riceve dal servizio SOAP non è XML valido. L'attributo xmlns deve essere assoluto URI.

Ciò significa il nome del namespace deve essere sotto forma: <scheme>:<scheme-specific-part>

Affinché l'XML sia valida, il servizio che si sta chiamando deve essere rimandando urn:ElsyArres.API come il valore dello spazio dei nomi.

<SearchFlightsResponse xmlns="urn:ElsyArres.API"> 

tuo file del pacchetto-info sarebbe quindi simile al seguente:

@XmlSchema( 
    namespace = "urn:ElsyArres.API", 
    elementFormDefault = XmlNsForm.QUALIFIED) 
package com.myProject.wegolo 

import javax.xml.bind.annotation.XmlNsForm; 
import javax.xml.bind.annotation.XmlSchema; 

Se non è possibile ottenere il servizio per risolvere il problema URI è possibile rimuoverlo mentre unmarshalling attraverso l'uso di un SAXFilter. Ecco un ottimo esempio che supporta sia l'aggiunta che la rimozione di spazi dei nomi durante lo smantellamento: https://stackoverflow.com/a/2148541/73446

Answer 3

Quando si esegue unmarshalling sto analizzando il file xml e dando l'unico elemento di classe. Per il tuo caso: dai la seguente stringa a unmarshaller, questo ti risparmia molti errori noiosi. Dopodiché, se ricevi un errore puoi provare a rimuovere anche xmlns = "ElsyArres.API". Anche le cose dello spazio dei nomi possono generare errori.
