Describing a string array in a wsdl file

Question

I'm using the globus toolkit for a project. In my service i have a resource: a string array. I want to get this resource from an Android client. How can I do that? How can I describe in the wsdl file the type "array of string"? Thank you.

I guess you're looking for this

<complexType name='ArrayOfString'>
    <sequence>
        <element name='item' type='xsd:string' maxOccurs='unbounded'/>
    </sequence>
</complexType>

Source: http://www.activebpel.org/samples/samples-2/BPEL_Samples/Resources/Docs/arrays.html

UPDATE:

I've done a test using NetBeans 7.0.1. The results were this:

Declare a method that receives a String[] parameter:

@WebMethod(operationName = "helloArray")
public String helloArray(@WebParam(name = "name") String[] name) {
    StringBuilder sb = new StringBuilder("Hello ");
    if (name != null) {
        for(int i = 0; i < name.length; i++) {
            sb.append(name[i]);
            if (i < (name.length - 1)) {
                sb.append(" and ");
            }
        }
    }
    sb.append('!');
    return sb.toString();
}

The WSDL generated a complex type for my method with a String array element

<xs:complexType name="helloArray">
    <xs:sequence>
        <xs:element name="name" type="xs:string" nillable="true" minOccurs="0" 
            maxOccurs="unbounded"/>
    </xs:sequence>
</xs:complexType>

In the client, the IDE generated a List<String> to consume it:

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "helloArray", propOrder = {"name"})
public class HelloArray {

    @XmlElement(nillable = true)
    protected List<String> name;

    public List<String> getName() {
        if (name == null) {
            name = new ArrayList<String>();
        }
        return this.name;
    }
}

And a method to consume the service

private String helloArray(java.util.List<java.lang.String> name) {
    edu.home.wsclient.HelloWorldWS port = service.getHelloWorldWSPort();
    return port.helloArray(name);
}

I've uploaded both projects in this address

Thank you. Now when I get the response from the client, as a generic Java object, and I try to cast it to a (String []) I get a ClassCastException. — Matteo Reda, May 07 '12 at 14:03
I also get an Exception in validating the wsdl: ArrayOfString is referenced but not defined! — Matteo Reda, May 07 '12 at 14:12
when I call the getClass() method on the response it returns me java.lang.String. I wonder why! — Matteo Reda, May 07 '12 at 15:42

You can use a custom type which has a String element (and more data, if you'd like) with multiplicity > 1.

<xsd:sequence>
  <xsd:element name="YourClass" type="pre:YourClass" maxOccurs="unbounded" minOccurs="0">
  </xsd:element>
</xsd:sequence>

How do I cast the Object returned by the response? If I try with (String []) I get a ClassCastException. – Matteo Reda May 07 '12 at 15:29

Have the XML call out a parent tag with multiple children, each with one string value from your array:

<parent>
    <child>String 1</child>
    <child>String 2</child>
</parent>

Name the tags appropriately.
