BaseModel and QName attributes

[objectiser]

Hi

I have a ComponentImplementationModel that has an attribute which is a QName. Currently this gets returned as a string, but then I only get the namespace prefix and local part, whereas I would actually like to have the qname (i.e. namespace and local part).

There does not seem to be an obvious way to resolve the namespace on the model - can someone point me in the right direction? just wondering whether there should be a 'getModelAttributeAsQName' method on the BaseModel?

Thanks in advance.

Regards

Gary

There isn't a direct way on the interface right now, however:

1. I added a jira to cover this: https://issues.jboss.org/browse/SWITCHYARD-1058
2. You can, for now:

// pseudo

public class MyModel extends BaseModel {

    public QName getFoo() {

        String foo = getModelAttribute("foo");

        if (foo != null && foo.indexOf(':') != -1) {

            String [] split = foo.split(":", 2);

           Map<String,String> map = getModelConfiguration().getPrefixNamespaceMap();

            String ns = map.get(split[0]);

            String localName = split[1];

            return new QName(ns, localName);

        }

    }

}

Thanks David, I'll give it a go.

Unfortunately didn't work. I have the following switchyard.xml:

<?xml version="1.0" encoding="UTF-8"?>
<switchyard xmlns="urn:switchyard-config:switchyard:1.0"
             xmlns:swyd="urn:switchyard-config:switchyard:1.0"
             xmlns:trfm="urn:switchyard-config:transform:1.0"
             xmlns:bean="urn:switchyard-component-bean:config:1.0"
             xmlns:soap="urn:switchyard-component-soap:config:1.0"
             xmlns:bpel="http://docs.oasis-open.org/ns/opencsa/sca/200903"
             xmlns:sca="http://docs.oasis-open.org/ns/opencsa/sca/200912"
             xmlns:ls="http://example.com/loan-approval/loanService/"
             xmlns:ra="http://example.com/loan-approval/riskAssessment/"
             targetNamespace="urn:switchyard-quickstart:bpel-loan-approval:0.1.0"
             name="loanapproval">
     <sca:composite name="loanservice" targetNamespace="urn:bpel:test:1.0">
        <sca:service name="loanService" promote="loanService">
            <soap:binding.soap>
                <soap:wsdl>loanServicePT.wsdl</soap:wsdl>
                <soap:socketAddr>localhost:18001</soap:socketAddr>
            </soap:binding.soap>
         </sca:service>

         <sca:component name="loanService">
             <bpel:implementation.bpel process="ls:loanApprovalProcess" />
             <sca:service name="loanService">
                 <sca:interface.wsdl interface="loanServicePT.wsdl#wsdl.porttype(loanServicePT)"/>
             </sca:service>
             <sca:reference name="riskAssessor" >
                 <sca:interface.wsdl interface="riskAssessmentPT.wsdl#wsdl.porttype(riskAssessmentPT)"/>
             </sca:reference>
         </sca:component>
         
         <sca:component name="riskAssessor" >
             <bpel:implementation.bpel process="ra:riskAssessmentProcess" />
             <sca:service name="riskAssessor">
                 <sca:interface.wsdl interface="riskAssessmentPT.wsdl#wsdl.porttype(riskAssessmentPT)"/>
             </sca:service>
         </sca:component>

     </sca:composite>
</switchyard>

When I attempt to retrieve the QName for the first "bpel:implementation" model element, the namespace/prefix map contains:

map={ns0=http://www.w3.org/2000/xmlns/, ns1=http://docs.oasis-open.org/ns/opencsa/sca/200903}

Okay, I'll squeeze something into 0.6.0-SNAPSHOT for you later today.

Sorry; it's gonna hafta be tomorrow.

Gary,

I finally submitted a pull request that fixes https://issues.jboss.org/browse/SWITCHYARD-1058 for you.

You can now call getModelAttributeAsQName(String):QName or getModelAttributeAsQName(QName):QName.  You can also set model attibutes as qnames.

I tested it with your XML, and I get the proper qnames out per your examples, testing the prefix, namespace and local parts are all good:

pfx: ls

ns: http://example.com/loan-approval/loanService/

lp: loanApprovalProcess

pfx: ra

ns: http://example.com/loan-approval/riskAssessment/

lp: riskAssessmentProcess

So once this gets processed, you should be good to go.  Thanks for your patience!

Sincerely,

David
