[graap-wg] WSAG schema to java stubs: a confusion

[Mumtaz Siddiqui]

Hi,

There is a confusion between schema description and generated Java stubs.
According to the WSAG specifications, multiple ServiceDescriptionTerms and
Preferences can be defined/described as shown in appendix 2/3 examples.

But, when we generate Java stubs (using WSDL2Java emmiter or castor), the
generated stubs provide these fields as single element instead of array 
or vector.
For examle TermCompositorType  class:

public class TermCompositorType  implements java.io.Serializable {
    private org.ggf.wsag.TermCompositorType exactlyOne;
    private org.ggf.wsag.TermCompositorType oneOrMore;
    private org.ggf.wsag.TermCompositorType all;
  
    private org.ggf.wsag.ServiceDescriptionTermType serviceDescriptionTerm;
    //???? Should not it array like ServiceDescriptionTermType[]????

    private org.ggf.wsag.ServiceReferenceType serviceReference;
    private org.ggf.wsag.ServicePropertiesType serviceProperties;
    private org.ggf.wsag.GuaranteeTermType guaranteeTerm;

    public TermCompositorType() {
    }
    ...
}

Here I expect ServiceDescriptionTermType[] instead of 
ServiceDescriptionTermType.
probably, here we can use domain specific terms like JobDefinition from 
JSDL as

    JobDefinition_Type[] jdefs = new JobDefinition_Type[2];
    jdefs[0] = new JobDefinition_Type();
    jdefs[1] = new JobDefinition_Type();
    sdterm.set_any(AnyHelper.toAnyArray(jdefs));
    sdterm.setServiceName(new NCName("job1"));

In this case the serialized XML document does not look like as expected! 
See the serialized
form below:

<agreement>
 ....
  <ns2:ServiceDescriptionTerm ns2:ServiceName="job1" 
xsi:type="ns2:ServiceDescriptionTermType">
    <ns3:value xsi:type="ns4:JobDefinition_Type"
          xmlns:ns3="http://www.globus.org/namespaces/2004/06/core"
          xmlns:ns4="http://schemas.ggf.org/jsdl/2005/11/jsdl">
                   <ns4:JobDescription 
xsi:type="ns4:JobDescription_Type" xsi:nil="true"/>
    </ns3:value>
    <ns5:value xsi:type="ns6:JobDefinition_Type"
          xmlns:ns5="http://www.globus.org/namespaces/2004/06/core"
          xmlns:ns6="http://schemas.ggf.org/jsdl/2005/11/jsdl">
                   <ns6:JobDescription 
xsi:type="ns6:JobDescription_Type" xsi:nil="true"/>
    </ns5:value>
   </ns2:ServiceDescriptionTerm>
....
</agreement>

Similarly, in case of BusinessValueListType class

public class BusinessValueListType  implements java.io.Serializable {
    private java.lang.Integer importance;
    private org.ggf.wsag.CompensationType[] penalty;
    private org.ggf.wsag.CompensationType[] reward;
    private org.ggf.wsag.PreferenceType preference; <<<<<<????????
    private java.lang.Object[] customBusinessValue;

    public BusinessValueListType() {
    }
 ...
}

again I expect PreferenceType field as array like  PreferenceType[].

Probably my understanding is wrong or the Java stubs are incorrectly
generated. Would be great if someone could explain it? How to specify
multiple terms and preferences using generated Java stubs?

Thanks

PS: Typo in wsag draft page 25? "A guarantee term can have one or more 
service scopes.
A service scope describes to what service element specifically a service 
applies."
May be the last 'service' is to be replaced with 'guarantee'?
