Error when returning an array

[juergen.zimmermann]

A method of a web service should return an array, namely KundeData[].

JBossWS generates this portion in the WSDL:

 <complexType name="KundeData">
 <sequence>
 <element name="art" nillable="true" type="string"/>
 <element name="id" type="long"/>
 <element name="nachname" nillable="true" type="string"/>
 <element name="rabatt" type="int"/>
 <element name="vorname" nillable="true" type="string"/>
 </sequence>
 </complexType>
 <complexType name="KundeData.Array">
 <sequence>
 <element maxOccurs="unbounded" minOccurs="0" name="value" nillable="true" type="tns:KundeData"/>
 </sequence>
 </complexType>

The ANT task "wstools" generates this portion for jaxrpc-mapping.xml:

 <wsdl-return-value-mapping>
 <method-return-value>de.hska.ws.KundeData[]</method-return-value>
 <wsdl-message xmlns:wsdlMsgNS='http://ws.hska.de/jaws'>wsdlMsgNS:KundenverwaltungService_findKundenByNachnameResponse</wsdl-message>
 <wsdl-message-part-name>result</wsdl-message-part-name>
 </wsdl-return-value-mapping>

When a client invokes the web service this stack trace is produced:

Hi,

Couple of thoughts -

I haven't used inner classes in any of my WS interface classes, and Id be a bit nervous about it, just based on the naming issues.

Also, I've found that arrays are best handled wrapped inside another class, that just contains that array.

So instead of

public Foo[] bar(String input) { ... }

Try

FooList bar(String input) { ... }

and in a separate class

public class FooList {
public Foo[] foos;
}

Good luck!

A JavaBean wrapper for the array solved the problem. Thanks.

BTW, I was not using inner classes althought the error message suggested so.

This should be fixed in jbossws-1.0.1. Please try the latest

[juergen.zimmermann]

http://labs.jboss.com/portal/index.html?ctrl:id=page.default.downloads&project=jbossws shows only 1.0.0GA.

Is 1.0.1 already available? If so, where can I download it. Thanks.
