returning a 2-d array

[archit thakur]

can a 2-d array be returned from the method of end point implementation class generated using annotations?
if not, what is the solution to the problem?

Hi!
With the following method in the endpoint implementation class:

...
    @WebMethod(operationName="test2d")
    public String[][] test2d()
    {
        String [][]test = new String[5][5];

        // Fill in some data into the 2D array.

        return test;
    }
...

If we then look at the generated WSDL, there is the following type declared for the reply of the above method:

<xs:complexType name="test2dResponse">
    <xs:sequence>
        <xs:element name="return" type="ns1:stringArray" nillable="true" minOccurs="0" maxOccurs="unbounded" />
    </xs:sequence>
</xs:complexType>

The stringArray type is type predefined by JAXB that appears in a separate XML schema:

<xs:complexType name="stringArray" final="#all">
    <xs:sequence>
        <xs:element name="item" type="xs:string" minOccurs="0" maxOccurs="unbounded" nillable="true" />
    </xs:sequence>
</xs:complexType>

Thus the data returned from the method will be a list of stringArray-s.
Best wishes!
