Hi Vinh,
How I can define XSD schema that mentioned here? and how to reference that
from my services.xml? should i put these is a xml file and put the file in
classpath?
<xs:complexType name="StringArrayType">
<xs:sequence>
<xs:element name="Item" type="xs:string" minOccurs="0"
maxOccurs="unbounded"/>
</xs:sequence>
</xs:complexType>
<xs:element name="StringArray" type="tns:StringArrayType"/>
<xs:complexType name="2DStringArrayType">
<xs:sequence>
<xs:element ref="StringArray" minOccurs="0"
maxOccurs="unbounded"/>
</xs:sequence>
</xs:complexType>
<xs:element name="2DStringArray" type="tns:2DStringArrayType"/>
Please tell me the real file format of XSD Schema.

RE: Does Axis2 support 2D/2D object array as return type?

Hi,
Please see the attached email where I tried to address your question:)
The idea with web services is that you can pass/return any type of
object as long as you define an XML schema for it. The schema
definition tells the data binding tooling (i.e. ADB, XmlBeans, etc) how
to convert your type to/from XML.
So if you want to return a multi-dimension array, you need to define an
object schema that has such a data structure. For example, the
following might work for you if you want to pass a 2D string[].
<xs:complexType name="StringArrayType">
<xs:sequence>
<xs:element name="Item" type="xs:string" minOccurs="0"
maxOccurs="unbounded"/>
</xs:sequence>
</xs:complexType>
<xs:element name="StringArray" type="tns:StringArrayType"/>
<xs:complexType name="2DStringArrayType">
<xs:sequence>
<xs:element ref="StringArray" minOccurs="0"
maxOccurs="unbounded"/>
</xs:sequence>
</xs:complexType>
<xs:element name="2DStringArray" type="tns:2DStringArrayType"/>
