Is it possible to retrive multiple objects at one time ?

[Alex Parvan]

For example, i have a getUsersOnline() method on a WebService that returns the users online at that time. The User object (and xml schema) will contain the name, age and location of each user.

So, can i retreive more than one User object ? Like an array of users ? Maybe 1 user, maybe 3, maybe 10.

Hi!
Yes, of course you can retrieve many Users.
If you do Java-first development and the return type of a method in the endpoint implementation class is String[], then the following XML complex type will be generated:

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

If you do WSDL-first development, then use the maxOccurs attribute, as seen above, to define an array of some type.
Best wishes!

Great ! Thanks, i'll post here again if i'm having trouble, please check it again tomorrow or so :P

It works, if anyone else needs this, my xsd looks like this:

<xsd:complexType name="UserList">
        <xsd:sequence>
            <xsd:element name="User" minOccurs="0" maxOccurs="unbounded" nillable="true">
                <xsd:complexType>
                    <xsd:sequence>
                        <xsd:element name="Name" type="xsd:integer"/>
                        <xsd:element name="Age" type="xsd:int"/>
                        <xsd:element name="Location" type="xsd:string"/>
                    </xsd:sequence>
                </xsd:complexType>
            </xsd:element>
        </xsd:sequence>
    </xsd:complexType>

And then you can use it in Java like this:

UserList.User user = new UserList.User();
user.setName("Name");
user.setAge(99);

Thank you Ivan.
