It also works for typeMapping, ( I cant explain why I had failures first time I tried).
Thanks

Christophe,
Yes, it works now. But, I had to use beanMapping and not TypeMapping tags. (I will try again with type mapping).
Secondly, the process here is important-- after adding the new mapping information to WSDD, I had to regenerate the proxies. ( This is for anybody else who might have a similar problem)
Thanks for your help.
Regards
Sagar

As far as I understand Party is your abstract class. You need to declare the derived type:
If you have:
public class MyConcreteParty extends Party { … }
Declare:
<typeMapping xmlns:ns=" http://businessClasses.pmf.chordiant.com" qname="ns:MyConcreteParty" type=" java:com.chordiant.pmf.businessClasses.MyConcreteParty " serializer="org.apache.axis.encoding.ser.BeanSerializerFactory" deserializer="org.apache.axis.encoding.ser.BeanDeserializerFactory" encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" />

Thanks for the response. I did declare these abstract classes as beans with BeanMapping in WSDD file for this service. It does cause trouble, even with mappings specified.
I will do some more experiments. I really don’t want to go and convert all abstract classes to Normal classes. I have tried this and it does resolve the problem in some cases.
I will report back my findings.
Please respond with any other ideas.
Here is my bean mapping in my WSDD file.
<beanMapping xmlns:ns="http://businessClasses.pmf.chordiant.com" qname="ns:Party" languageSpecificType="java:com.chordiant.pmf.businessClasses.Party" />

Works fine for me (axis1.1, rpc-enc), just declared your derived types in the wsdd.

Hi,
I am experiencing some problems while instantiating some of the business objects on the server. This could be because the base classes are abstract and any attempt use these objects in a parameter would require such an object’s instantiation. In our native code usage such base class objects like Person were obtained from a factory and probably type cast because we were controlling/developing the code.
When axis tries to instantiate a Party, it fails because Party is an abstract class and can not be instantiated. We may have a problem with abstract classes (at run time), just as we had problem with interfaces as parameters ( at proxy generation time) in a method call.
Given below is the call I am trying to make on the client
Vector RETVAL = partyRoleCA.getAllPaymentMethods(userName, authentication, (Party)myPerson);
The Axis server receives the call through a SOAP message and tries to instantiate a Party object and then…..
Given below is the error message received from the server.
faultString: org.xml.sax.SAXException: Unable to create JavaBean of type com.chordiant.pmf.businessClasses.Party. Missing default constructor? Error was: java.lang.InstantiationException: com/chordiant/pmf/businessClasses/Party.
Can anybody confirm this observation? Is there a way around the problem?
Regards
Sagar
