We are upgrading an old web service based on Axis 1.2 to 1.4 so that we
can start using Java5 (way belatedly) and I am having problems with the
deserialization of a HashMap. This always worked easily in 1.1 and 1.2
but not in axis 1.3 or 1.4.
The error is this;
SEVERE: Could not convert [Lorg.apache.xml.xml_soap.MapItem; to bean
field 'attributes', type java.util.HashMap
Basically it seems that the MapDeserializer is not doing its thing and
is trying to set the array of MapItems into a slot that is supposed to
have a deserialized HashMap.
======== the setup ==============
Basically, I have a class that inherits from HashMap (TaskInfoAttributes
extends HashMap). The typemapping is registered in the wsdd file as
follows;
<typeMapping
deserializer="org.apache.axis.encoding.ser.MapDeserializerFactory"
encodingStyle="http://schemas.xmlsoap.org/soap/encoding/";
qname="ns7:TaskInfoAttributes"
serializer="org.apache.axis.encoding.ser.MapSerializerFactory"
type="java:java.util.HashMap" xmlns:ns7="TaskIntegrator"/>
When I generate the stub from the WSDL (wsdl2j), the server shows this
warning;
2006-11-22 07:12:36.815 The class
org.genepattern.webservice.TaskInfoAttributes
extends non-bean class java.util.HashMap. An xml schema anyType will be
used to define org.genepattern.webservice.TaskInfoAttributes in the
wsdl file.
Now I compile the stub and try to call a method that returns another
object holding on to one of these TaskInfoAttribute/HashMap objects and
I see the following error;
Nov 22, 2006 6:58:08 AM
org.apache.axis.encoding.ser.BeanPropertyTarget set
SEVERE: Could not convert [Lorg.apache.xml.xml_soap.MapItem; to bean
field 'attributes', type java.util.HashMap
Nov 22, 2006 6:58:08 AM org.apache.axis.client.Call invoke
SEVERE: Exception:
java.lang.IllegalArgumentException: argument type mismatch
at
org.apache.axis.encoding.ser.BeanPropertyTarget.set(BeanPropertyTarget.java:157)
at
org.apache.axis.encoding.DeserializerImpl.valueComplete(DeserializerImpl.java:249)
=============================================================
So has anybody sucessfully gotten a Map class to serialize/deserialize
that would be willing to explain to me where I have gone wrong?
Thanks
Ted
