Array Deserialized Incorrectly

[Ma...@micorp.com]

Hi,

I used java2wsdl when publishing an axis service.  The service method 
expects a parameter class with contains an array of a different 
(non-primitive) class.  The client has no problem calling the service, and 
the service does almost everything perfectly.  However, no matter how many 
array elements I send to the service, it only receives an array of length 
= 1 for processing.

Here is the wsdl:

  <?xml version="1.0" encoding="UTF-8" ?>

When the client inserts 3 metrics, here is the outgoing SOAP request XML 
as picked up by the Handler:

<?xml version="1.0" encoding="UTF-8"?>
<soapenv:Envelope 
xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"

     <level>0</level>
     <metricCreator>testSendMetric_1</metricCreator>
     <metricName>my metric_1</metricName>
     <type>1</type>
    </metricsArray>
    <metricsArray>
     <begin>1087312889439</begin>
     <dateTime>1087317889439</dateTime>
     <end>1087313889439</end>
     <level>0</level>
     <metricCreator>testSendMetric_2</metricCreator>
     <metricName>my metric_2</metricName>
     <type>1</type>
    </metricsArray>
    <metricsArray>
     <begin>1087312889439</begin>
     <dateTime>1087317889439</dateTime>
     <end>1087313889439</end>
     <level>0</level>
     <metricCreator>testSendMetric_3</metricCreator>
     <metricName>my metric_3</metricName>
     <type>1</type>
    </metricsArray>
   </in0>
  </processMetricComposite>
 </soapenv:Body>
</soapenv:Envelope>

Again, during processing, the service implementation only gets an array 
(of Metric) of length = 1.  The message completes, albeit with what 
appears to be partial input, and flawlessly returns a positive response to 
the client.

Am I doing something wrong here javs2wsdl?  The only place that I am a 
little concerned about is the axis-generated MetricComposite definition. I 
can include additional bits upon request.  The typeDesc is initialized in 
the following manner:

public class MetricComposite  implements java.io.Serializable {
    private int metricLevel;
    private java.lang.String metricSponsor;
    private com.micorp.metrics.Metric[] metricsArray;

    public MetricComposite() {
    }
.
.
.

    public com.micorp.metrics.Metric[] getMetricsArray() {
        return metricsArray;
    }

    public void setMetricsArray(com.micorp.metrics.Metric[] metricsArray) {
        this.metricsArray = metricsArray;
    }

.
.
.

    // Type metadata
    private static org.apache.axis.description.TypeDesc typeDesc =
        new org.apache.axis.description.TypeDesc(MetricComposite.class);

    static {
        typeDesc.setXmlType(new javax.xml.namespace.QName("http://metrics.MY_COMPANY.com", "MetricComposite"));
        org.apache.axis.description.ElementDesc elemField = new org.apache.axis.description.ElementDesc();
        elemField.setFieldName("metricLevel");
        elemField.setXmlName(new javax.xml.namespace.QName("", "metricLevel"));
        elemField.setXmlType(new javax.xml.namespace.QName("http://www.w3.org/2001/XMLSchema", "int"));
        typeDesc.addFieldDesc(elemField);
        elemField = new org.apache.axis.description.ElementDesc();
        elemField.setFieldName("metricSponsor");
        elemField.setXmlName(new javax.xml.namespace.QName("", "metricSponsor"));
        elemField.setXmlType(new javax.xml.namespace.QName("http://www.w3.org/2001/XMLSchema", "string"));
        typeDesc.addFieldDesc(elemField);
        elemField = new org.apache.axis.description.ElementDesc();
        elemField.setFieldName("metricsArray");
        elemField.setXmlName(new javax.xml.namespace.QName("", "metricsArray"));
        elemField.setXmlType(new javax.xml.namespace.QName("http://metrics.MY_COMPANY.com", "Metric"));
        typeDesc.addFieldDesc(elemField);
    }

I thought the metricsArray definition would have possibly suggested an 
array of Metric (i.e., Metric[]) rather than simply Metric, but I may not 
be comfortable enough at this point with the code.

Thanks, in advance, for taking a look at the source.

RE: Array Deserialized Incorrectly

[Anne Thomas Manes <an...@manes.net>]

 Well for starters, you shouldn't use soapenc:Array  with document/literal
services.
I notice that your SOAP message isn't generated properly. It should contain
an element called <metricsArray>, which should contain a set of three
<metric> elements, except that instead you get three <metricsArray>
elements. The service sees only the one array element in the first array and
ignores the following two (unexpected) elements. I suspect it's because
you've defined the array using soapenc:Array.
 
What version of Axis are you using? I suggest you use the latest Axis 1.2
build.
