Patrick Houbaux commented on AXIS-1746:
---------------------------------------

Ok it seems that I found a workaround to this.

Declaring the type mapping for the primitive types in the deployment wsdd file seems to do
the trick.

Is this the correct way?

Meaning adding the following to deploy.wsdd of the webservice:

<typeMapping  qname="ns:double"
            xmlns:ns="http://www.w3.org/2001/XMLSchema"
            type="java:java.lang.Double" 
            serializer="org.apache.axis.encoding.ser.SimpleSerializerFactory" 
            deserializer="org.apache.axis.encoding.ser.SimpleDeserializerFactory" 
            encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"/>
      
<typeMapping  qname="ns:int"
            xmlns:ns="http://www.w3.org/2001/XMLSchema"
            type="java:java.lang.Integer" 
            serializer="org.apache.axis.encoding.ser.SimpleSerializerFactory" 
            deserializer="org.apache.axis.encoding.ser.SimpleDeserializerFactory" 
            encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"/>
                    
<typeMapping  qname="ns:boolean"
            xmlns:ns="http://www.w3.org/2001/XMLSchema"
            type="java:java.lang.Boolean" 
            serializer="org.apache.axis.encoding.ser.SimpleSerializerFactory" 
            deserializer="org.apache.axis.encoding.ser.SimpleDeserializerFactory" 
            encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"/>
                    
<typeMapping  qname="ns:long"
            xmlns:ns="http://www.w3.org/2001/XMLSchema"
            type="java:java.lang.Long" 
            serializer="org.apache.axis.encoding.ser.SimpleSerializerFactory" 
            deserializer="org.apache.axis.encoding.ser.SimpleDeserializerFactory" 
            encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"/>
                    
<typeMapping  qname="ns:float"
            xmlns:ns="http://www.w3.org/2001/XMLSchema"
            type="java:java.lang.Float" 
            serializer="org.apache.axis.encoding.ser.SimpleSerializerFactory" 
            deserializer="org.apache.axis.encoding.ser.SimpleDeserializerFactory" 
            encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"/>
                    
<typeMapping  qname="ns:byte"
            xmlns:ns="http://www.w3.org/2001/XMLSchema"
            type="java:java.lang.Byte" 
            serializer="org.apache.axis.encoding.ser.SimpleSerializerFactory" 
            deserializer="org.apache.axis.encoding.ser.SimpleDeserializerFactory" 
            encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"/>
                    
<typeMapping qname="ns:short"
            xmlns:ns="http://www.w3.org/2001/XMLSchema"
            type="java:java.lang.Short"
            serializer="org.apache.axis.encoding.ser.SimpleSerializerFactory" 
            deserializer="org.apache.axis.encoding.ser.SimpleDeserializerFactory" 
            encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"/>

> Using a RPC web service using complex data types (exposed java beans with primitive type
properties).
> Using Multi-Ref because the data type model is a graph.
> BUG: For the primitive type properties of the beans sent through the wire, Axis sent
them as multi ref.
> Explanation:
> After a debugging session with the Axis 1.2RC2 source, noticed that the SerializationContext.isPrimitive
method in org.apache.axis.encoding return false for these simple types.
> The method    public void serialize(QName elemQName,
>                           Attributes attributes,
>                           Object value,
>                           QName xmlType,
>                           Boolean sendNull,
>                           Boolean sendType)
> at line 727 is called with a correct xmlType (i.e. (http://www.w3.org/2001/XMLSchema)double
for instance) parameter for the simple type but in the body of this method the checking if
the value is a primitive (line 802) is not taking into account this correct xmlType.
> In the method isPrimitive the following test(starting at line 609) fails:
>         // Note that java.lang wrapper classes (i.e. java.lang.Integer) are
>         // not primitives unless the corresponding type is an xsd type.
>         // (If the wrapper maps to a soap encoded primitive, it can be nillable
>         // and multi-ref'd).
>         QName qName = getQNameForClass(javaType);
>         if (qName != null && Constants.isSchemaXSD(qName.getNamespaceURI()))
{
>             if (SchemaUtils.isSimpleSchemaType(qName)) {
>                 return true;
>             }
>         }
> During the debug runtime the values in the previous piece of code are the following:
> - javaType = java.lang.Double
> - qName = (http://schemas.xmlsoap.org/soap/encoding/)double
> Why qName don't get the value : (http://www.w3.org/2001/XMLSchema)double?
> Following an example of what is sent through the wire.
> p.s.: Orginally sent in the axis-user mailing list, thread:
