Deserialization Problem

[rajaguru ganesan <ra...@gmail.com>]

Hi,

I am facing problem while deserializing SOAP responses containing an
Object encapsulating an Array of Objects(Please see the Examples
below).  I am using AXIS 1.2.1. I have used WSDL2JAVA to generate
client stubs.

The Error Message is below:

Caught Exception from Example:org.xml.sax.SAXException: No

pleService}MyClass

Following are the classes:

Original java Classes:
================
package package1;
public class MyClass
{
       public String string;
}


package package1;
public class ExampleCollection
{
       public MyClass[] myClass;
}



Service Class:
==========
package package1;
public class ExampleService
{
       public ExampleCollection returnExampleCollection()
       {
               ExampleCollection exampleCollection=new ExampleCollection();

               MyClass myClassObject[]=new MyClass[2];
               myClassObject[0]=new MyClass();
               myClassObject[1]=new MyClass();
               myClassObject[0].string=new String("Test1");
               myClassObject[1].string=new String("Test2");

               exampleCollection.myClass=myClassObject;
               return exampleCollection;
       }

       public ExampleCollection testExampleCollection(ExampleCollection e)
       {
               return e;
       }

       public MyClass[] testArray(MyClass[] m)
       {
               return m;
       }

}

server-config.wsdd file:
=================
<service name="ExampleService" provider="java:RPC">
<parameter name="allowedMethods" value="*"/>
<parameter name="className" value="package1.ExampleService"/>
<beanMapping qname="myNS:ExampleCollection"
xmlns:myNS="urn:ExampleService"
languageSpecificType="java:package1.ExampleCollection"/>
<beanMapping qname="myNS:MyClass" xmlns:myNS="urn:ExampleService"
languageSpecificType="java:package1.MyClass"/>
</service>

client code:
========
import ExampleService_pkg.*;

class TestExam{

 public static void main(String args[]){


       try {

               ExampleCollection exampleCollection=new ExampleCollection();
               MyClass myClassObject[]=new MyClass[2];
               myClassObject[0]=new MyClass();
               myClassObject[1]=new MyClass();
               myClassObject[0].setString("Test1");
               myClassObject[1].setString("Test2");
               exampleCollection.setMyClass(myClassObject);

               ExampleServiceServiceLocator exLocator=new
ExampleServiceServiceLocator();

               AxisServletSoapBindingStub
exService=(AxisServletSoapBindingStub)exLocator.getAxisServlet();

               if(exService!=null)  {
                       System.out.println("Inside If Part ");
                       ExampleCollection
exampleCol=exService.returnExampleCollection();
                       ExampleCollection
examCol=exService.testExampleCollection(exampleCollection);
                       MyClass[] myCl=exService.testArray(myClassObject);
                       System.out.println("after calling ");

               } else {
                       System.out.println("Error");
               }


       } catch (Exception e) {
               System.out.println("Caught Exception from
Example:"+e.getMessage());
               e.printStackTrace();

   }

 }

}

testArray() method invocation completed succesfully without anyproblem.

But testExampleCollection() and returnExampleCollection() methods are  failing!.

That's I am unable to send or receive ExampleCollection.

Even I have tried adding the  following entries in
server-config.wsdd(both not at a time, one by one): but these changes
also don't improve anything.

<arrayMapping qname="myNS:ArrayOfMyClass"
languageSpecificType="java:package1.MyClass[]"
innerType="myNS:MyClass" xmlns:myNS="urn:ExampleService"
encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"/>


<typeMapping qname="myNS:ArrayOfMyClass" xmlns:myNS="urn:ExampleService"
            languageSpecificType="java:package1.MyClass[]"
            serializer="org.apache.axis.encoding.ser.ArraySerializerFactory"
            deserializer="org.apache.axis.encoding.ser.ArrayDeserializerFactory"
            encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"/>
