Title: .NET and Axis

Hi Dino,

 

thanks for your suggestion but I have found that I can generate helper classes using --helperGen on the WSDL2Java command.  These helper classes contain the typeDesc code that Axis uses for it serialization.  BeanSer/Deser actually tries to load these _Helper classes if the getTypeDesc static method is not found is the X.class in order to get the TypeDesc.

 

I have found that I need to use a variation of the WSDL first approach as the axis generated WSDL contains ArrayOf elements which I cannot get to work with my .NET client.

 

But I can use my existing classes and a wrapped/literal service if I include the generated Helper classes and edit the WSDL as below.   

 

The steps I follow are therefore:

1. Java2WSDL

2. Edit the ArrayOf XML

3. WSDL2Java using --helperGen

 

and it works.

 

Thanks for all your help.

 

<complexType name="ArrayOf_tns2_X">

<sequence>

<element maxOccurs="unbounded" minOccurs="0" name="item" type="tns2:X"/>

</sequence>

....

<complexType name="Y">

<complexContent>

<sequence>

<element name="queries" nillable="true" type="impl:ArrayOf_X"/>

</sequence>

</complexContent>

</complexType>

gets changes to....

<element name="Y">

<complexType>

<sequence>

<element maxOccurs="unbounded" name="X1" type="tns2:X"/>

</sequence>

</complexType>

</element>

Aedmar, One last thing. . .

 

If I take your inquiry.wsdl, and modify it, I can generate a .NET client that accepts the response.xml that you included previously. 

 

The modifications are:

 

- collapse all <schema> into a single <schema>, targetNamespace="http://inquiry.webservice.gpb.rbc.com"

-  re-define tns3 and tns4 to be "inquiry.webservice.gpb.rbc.com" rather than util... and customer....

 

In other words, effectively I redefine all types used in the wsdl to reside in a single namespace.  ("inquiry.blah.blah"). 

 

Then, the .NET client generated from such a WSDL can consume the response document you sent out.

 

I don't feel quite right in doing this.  Effectively I have turned the contract on its head - I am writing the WSDL to conform to the actual XML on the wire, rather than the other way 'round ("WSDL First", which as you know is the One True Way to Interop Enlightenment). 

 

But, on the other hand, WSDL is just a tool, no?   Modifying the WSDL in this way may be completely acceptable.  Of course, a better approach is to convince AXIS to generate a WSDL like that, automatically.   How?  Just modify the WSDD so that all your custom types (Code, BankIdentifier, GPBException, etc) all reside in the same XMLNS, "http://inquiry.webservice.gpb.rbc.com"

 

 

Then, the auto-gen'd WSDL should reflect the XML on the wire. 

 

-Dino

ahh, sorry, I don't know much about custom serializers for AXIS, someone else maybe on the list can help you with that.  maybe you need to restate the question (it has been a long-ish thread, and probably lots of people tuned out).

Hi Dino,

 

you can get it working because you are using the Axis generated Java beans which contains class specific Serializer and Deserializer code.

 

If I cut and paste the Axis generated Serializer and Deserializer code into my existing classes it works aswell. 

 

Thanks to you I have recognised the problem, i.e., that using the de/serializers specified in the server-config.wsdd file creates name space issues.

 

<typeMapping deserializer="org.apache.axis.encoding.ser.BeanDeserializerFactory" encodingStyle="" qname="ns5:BankIdentifier" serializer="org.apache.axis.encoding.ser.BeanSerializerFactory" type="java:com.rbc.gpb.util.BankIdentifier" xmlns:ns5="http://util.gpb.rbc.com"/>

<typeMapping deserializer="org.apache.axis.encoding.ser.BeanDeserializerFactory" encodingStyle="" qname="ns6:Code" serializer="org.apache.axis.encoding.ser.BeanSerializerFactory" type="java:com.rbc.gpb.util.Code" xmlns:ns6="http://util.gpb.rbc.com"/>

Any idea how I can continue to use my preexisting Java classes (and there are a lot of them) without having to cut and paste the de/serializer code into each of them?

 

Example of Axis generated Serializer and Deserializer code

private static org.apache.axis.description.TypeDesc typeDesc =

new org.apache.axis.description.TypeDesc(BankIdentifier.class, true);

static {

typeDesc.setXmlType(new javax.xml.namespace.QName("http://util.gpb.rbc.com", "BankIdentifier"));

org.apache.axis.description.ElementDesc elemField = new org.apache.axis.description.ElementDesc();

elemField.setFieldName("bank");

elemField.setXmlName(new javax.xml.namespace.QName("http://util.gpb.rbc.com", "bank"));

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("transit");

elemField.setXmlName(new javax.xml.namespace.QName("http://util.gpb.rbc.com", "transit"));

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("key");

elemField.setXmlName(new javax.xml.namespace.QName("http://util.gpb.rbc.com", "key"));

elemField.setXmlType(new javax.xml.namespace.QName("http://www.w3.org/2001/XMLSchema", "string"));

elemField.setNillable(true);

typeDesc.addFieldDesc(elemField);

elemField = new org.apache.axis.description.ElementDesc();

elemField.setFieldName("number");

elemField.setXmlName(new javax.xml.namespace.QName("http://util.gpb.rbc.com", "number"));

elemField.setXmlType(new javax.xml.namespace.QName("http://www.w3.org/2001/XMLSchema", "int"));

typeDesc.addFieldDesc(elemField);

}

/**

public static org.apache.axis.description.TypeDesc getTypeDesc() {

return typeDesc;

}

/**

public static org.apache.axis.encoding.Serializer getSerializer(
