Hi!
I'm having problems with a document style web service published with Axis
1.4.
I've implemented an operation wich returns a complex object wich has a
String[] attribute inside.
Here is the mapping for the element:
<complexType name="Group">
<sequence>
<element name="children" nillable="true"
type="impl:ArrayOf_xsd_anyType"/>
<element name="name" nillable="true" type="xsd:string"/>
<element name="parent" nillable="true" type="xsd:string"/>
</sequence>
</complexType>
<complexType name="ArrayOf_xsd_anyType">
<sequence>
<element maxOccurs="unbounded" minOccurs="0" name="item"
type="xsd:anyType"/>
</sequence>
</complexType>
The soap invocation returns an xsd:string for each String[] element.
When I invoke the operation with Axis I get:
15-may-2008 11:48:25 org.apache.axis.client.Call invoke
GRAVE: Exception:
java.lang.NullPointerException

Debuggin axis code, I see that Axis can't found a desearializer for the
elements inside String[] because it gets null xsi type for the elements.
I have added the bean mapping on server and client for the Group complex
type.
I think I don't need to add any deserializer for the String[].
Am I missing anything.
Any help will be greatly appreciated.
