[news.eclipse.modeling.m2m] [ATL]UML 2 BPEL transformation

[unique <hr_mi@xxxxxxx>]

Hi ,everyone :
   I want to transform a class diagram to bpel , it is defined like this:
    -----------------
        <<Data>>
      purchaseOrder
    -----------------
         attributes
    customerID:String
    orderID:String
    orderItem:OrderItem
    -----------------
       operations
    -----------------
         classes
    -----------------


and the WSDL is defined as following:

Corresponding WSDL fragment:

<element name="purchaseOrder">
   <complexType>
   <sequence>
       <element name="customerID" nillable ="true" type="xsd:string" />
       <element name="orderI" nillable ="true" type="xsd:string" />
       <element name="avaliability" nillable ="true" type="xsd:string"/>
   </sequence>
   </complexType>
</element>

<wsdl:message name="purchaseOrderMessage">
    <wsdl:part name="parameters" element="tns:purchaseOrder" />
    <wsdl:part name="attribute1" type=" xsd:string" />
</wsdl:message>


I am a new learner about this , who can help me make a rue for this
transformation ?


Thanks very much.
