Using HashMaps at WSDL?

Hi,

i defined an operation with WSDL and which should return an object which is derived from a HashMap. That's why the object has a method with two parameters.

Code:

---

put(fieldname,value)

---

So, this object isn't a bean anymore because of the two parameters. How can i specify such an object with WSDL? Is the following WSDL code correct? It's looking somehow odd.

Code:

---

<xsd:complexType name="MyHashObject">
  <xsd:sequence>
    <xsd:element name="put"  type="cas:TwoStrings" minOccurs="0" nillable="true"/>
...
<xsd:complexType name="TwoStrings">
  <xsd:sequence>
    <xsd:element name="string" type="xsd:string" nillable="true" minOccurs="2" maxOccurs="2" />
  </xsd:sequence>
</xsd:complexType>

---

Is it allowed to specify types in WSDL which are no beans?

How can i transfer the MyHashObject with all data? I mean, if i specify the operation with two paramteres a client can generate a class with that info, but the content of HashMap ist't transfered automatically(with Spring Marshall/Unmarshall), is it?

Cheers,

Ingo
