wie ArrayList an Webservice geben?

[Lenzen]

Ich versuch schon eine Ewigkeit eine ArrayList mit einem Webservice aufzurufen.
Mein Versuch:

Nun habe ich folgende Zeile auskommentiert:

@SOAPBinding(style=SOAPBinding.Style.RPC, use=SOAPBinding.Use.LITERAL)

Als Response bekomme ich (fast das was ich will):

      </ns2:testArrayListResponse>
   </S:Body>
</S:Envelope>

und einen Validerungsfehler:
Invalid xsi:type qname: 'xs:int'
Invalid xsi:type qname: 'xs:string'
Invalid xsi:type qname: 'xs:double'
Invalid xsi:type qname: 'xs:long'
Invalid xsi:type qname: 'xs:string'


Was mache ich falsch?

Mittlerweile denke ich, dass man komplexe Datentypen nicht an einen Webservice geben kann. Über eine Bean klappt das. Vielleicht hat ja noch jemand eine Idee?

Probier es mal mit dem List anstatt ArrayList als Rückgabetyp

[Frank04]

Eine ArrayList wird bei der Übertragung automatisch zur List. Der Client muss auch die erhaltenen Daten in eine List speichern.

Hast Du die Validation der Nachrichten an?

@WebService  
@SchemaValidation()

Auf einer Tomcat7 und einer Websphere 6.1 Implementierung funktioniert die Listenübergabe.
