RE: how to get rid of these warnings?

[Tami Wright]

Any complex objects being passed across the wire need to be standard bean types 
(getters/setters) with a default constructor in each.  java.util.List and 
net.sf.hibernate.Interceptor will not qualify because axis cannot marshall/unmarshall 
them into platform-independent/soap-compliant types.

Sample complex object for web service:

Class Product
{
        private String name;
        private String type;

        public Product(){}  //A default constructor takes not parameters
        
        public String getName()
        {
                return this.name;
        }

        public void setName(String name)
        {
                this.name = name;
        }

        public String getType()
        {
                return this.type;
        }

        public void setType(String type)
        {
                this.type = type;
        } 
} 

Sample web-service method using complex object Product:

Public Product getProduct(String productName)
{
        Product product = new Product();
        ... //Your code
        return product;
}

If you want to use List and Interceptor(Hibernate) the design pattern is to use them 
inside your web-service, but do not expose them to web service clients (Remote Fa�ade 
pattern).  So if you are doing some sort of object-relational mapping, do so, but 
don't use the tool's objects to be return types.  Use the tool to create your 
"Product" bean and then let the web-service return it to the client.  Remember, web 
services are for interoperability.  A .NET client wouldn't know how to operate on a 
Java List or Hibernate Interceptor.

Go through Java2Wsdl and Wsdl2Java again, and then see what happens.

Subject: how to get rid of these warnings?

I am trying to develop the service using Spring and Hibernate.
When I try to get the WSDL from the java classes I am getting the following
warnings:

WARNING: The class java.util.List is defined in a java or javax package and cann ot be 
converted into an xml schema type.  An xml schema anyType will be used to define this 
class in the wsdl file.


WARNING: The class net.sf.hibernate.Interceptor does not contain a default const 
ructor, which is a requirement for a bean class.  The class cannot be converted into 
an xml schema type.  An xml schema anyType will be used to define this clas s in the 
wsdl file.


I ignored the warnings and executed WSDL2Java command and the WSDD file was generated.
When I tried to deploy the service with that WSDD, I am getting error
message:


Null Response Message  

So I think the problem is with those warnings that I ignored earlier...

Can someone plz tell me how to remove those warnings??

Thanks,
SSSS
