BeanSerializer ignores namespace of arguments
---------------------------------------------

                 Key: AXIS-2625
                 URL: https://issues.apache.org/jira/browse/AXIS-2625
             Project: Axis
          Issue Type: Bug
          Components: Serialization/Deserialization
    Affects Versions: 1.4
         Environment: any, server is not Axis.
            Reporter: Hugo Hallman


When calling a web-service with parameter complex types in a different namespace than the service itself, the BeanSerializer does not set the namespace of the parameter attributes to that of the parameter type, but leaves the namespace to the namespace of the service, on the server side, the parameters will be parsed as null.

Example code
javax.xml.rpc.Service service;
service.getTypeMappingRegistry().getDefaultTypeMapping().register(ArgumentType.class, "qn-other-than-service's-qname", new BeanSerializerFactory(ArgumentType.class, qn), new BeanDeserializerFactory(ArgumentType.class, qn));


The problem was encountered on Axis 1.3, but looks to be the same on Axis 1.4 and on trunk:
http://svn.apache.org/repos/asf/webservices/axis/trunk/java/src/org/apache/axis/encoding/ser/BeanSerializer.java

This can be patched with a change in org.apache.axis.encoding.ser.BeanSerializer.java.
I have not tested that this suggestion does not break something else, but it solves the problem for me.

BeanSerializer is in serialize():178

From:
if (qname == null) {
     qname = new QName(isEncoded ? "" : name.getNamespaceURI(),
                        propName);
}

To:
if (qname == null) {
      qname = new QName(isEncoded ? "" : this.xmlType.getNamespaceURI(),
                         propName);
}

WORKAROUND:
In the call to service.getTypeMappingRegistry().getDefaultTypeMapping().register(), give a reference to the FixedBeanSerializerFactory, and 
copy the from http://svn.apache.org/repos/asf/webservices/axis/trunk/java/src/org/apache/axis/encoding/ser/BeanSerializer.java 
to FixedBeanSerializer where the above mentioned patch can be applied.
This solution works with XFire, and should also be appropriate for .net.

    /**
     * Creates a bugfixed serializer.
     */
    static class FixedBeanSerializerFactory extends BeanSerializerFactory {
        private static final long serialVersionUID = -8850895971122182792L;

        /**
         * Creates a new instance of <code>FixedBeanSerializerFactory</code>.
         * @param javaType
         * @param xmlType
         */
        public FixedBeanSerializerFactory(Class javaType, QName xmlType) {
            super(javaType, xmlType);
        }

        /**
         * Optimize construction of a BeanSerializer by caching the
         * type and property descriptors.
         */
        protected Serializer getGeneralPurpose(String mechanismType) {
            if ((javaType == null) || (xmlType == null)) {
                return super.getGeneralPurpose(mechanismType);
            }

            if (serClass == EnumSerializer.class) {
                return super.getGeneralPurpose(mechanismType);
            }

            return new FixedBeanSerializer(javaType, xmlType, typeDesc,
                propertyDescriptor);
        }
    }
