JbossWS array type issues

[agohar]

Hi,

I am having a problem with JBossWS for Array elements in wsdl. I am using JBoss-4.2.2.

One of my webservices method returns an object (complex type), which contains the array of other objects in it. Here is the snippt from my wsdl

 <xs:complexType name='MyVO'>
 <xs:sequence>
 <xs:element maxOccurs='unbounded' name='attr1' type='xs:string'/>
 <xs:element maxOccurs='unbounded' name='attr2' type='tns:MyOtherVO'/>
 <xs:element name='attr3' type='tns:MyOtherVO'/>
 <xs:element maxOccurs='unbounded' name='attr4' type='tns:MyOtherVO2'/>
 <xs:element name='attr5' type='xs:int'/>
 <xs:element name='attr6' type='xs:string'/>
 <xs:element name='attr7' type='xs:string'/>
 <xs:element name='attr8' type='xs:int'/>
 </xs:sequence>
 </xs:complexType>

This Object is returned from one of the webservices method and when attr2 and attr4 are null array or empty array, it doesn't return anything back to the soap client. I want it to return empty array.

Is it possible?

Thanks
