RE: Return type for complex types

[Uppili Srinivasan <us...@questerra.com>]

In case anyone is interested, I found a solution for this problem. 

 

If I modify my client to call "call.setReturnType(new QName("urn:myNS",
"myBean", ArrayList.class)", I am able to run the client without any
exceptions and access the returned array of objects.

 

IToo bad there are not enough examples or documentation on this.

Hi Rogério,

 

Thanks for your response. Your example uses RPC-style of service. I got
that working as well but for interoperability reasons and other reasons
we have switched to

"wrapped" and that is where I am having the problem in parsing the
response which contain an array of objects. Please let me know if you or
others have had any success with it.

Hi Uppili

  Try to create a wsdd like this:

<deployment xmlns=" http://xml.apache.org/axis/wsdd/" xmlns:java="
http://xml.apache.org/axis/wsdd/providers/java"
<http://xml.apache.org/axis/wsdd/providers/java> >
    <service name="YourWebServiceName" provider="java:RPC">
        <parameter name="className" value="your.package.ClassName"/> 
        <parameter name="allowedMethods" value="*"/>
        <beanMapping qname="myNS:YourBean" xmlns:myNS="urn:ClassName"
languageSpecificType="java:your.package.YourBean"/>
    </service>
</deployment>

  Deploy it then try this in your client code:

  QName qnYourBeanName = new QName("urn:ClassName", "YourBean");
  QName qnYourBeanArr = new QName("urn:ClassName", "ArrayOf_ClassName");
  call.registerTypeMapping(YourBean.class, qnYourBeanName ,  
                    new
org.apache.axis.encoding.ser.BeanSerializerFactory(YourBean.class,
qnYourBeanName ),  
                    new
org.apache.axis.encoding.ser.BeanDeserializerFactory(YourBean.class,
qnYourBeanName )); 
 
   call.registerTypeMapping(YourBean[].class, qnYourBeanNameArr , 
                    new
org.apache.axis.encoding.ser.ArraySerializerFactory(), 
                    new
org.apache.axis.encoding.ser.ArrayDeserializerFactory());

   YourBean[] yba = (YourBean[]) call.invoke( new Object[] {});

  This should work.
  Any problem let me know.

Best Regards,

Rogério Luz

Hi everyone,



I searched the recent archives for an answer to the problem I am having
but could not find one. Any help would be greatly appreciated.=20



I have a wrapped service which returns TestObject[] where TestObject is 
a bean with a just a String property.



The WSDD entry for that is



<service name=3D"Test" style=3D"wrapped">



  <parameter name=3D"className" = 

value=3D"com.questerra.webservices.Test"/>



  <parameter name=3D"allowedMethods" value=3D"*"/>



  <beanMapping qname=3D"myNS:TestObject" 

xmlns:myNS=3D" http://webservices.questerra.com"

languageSpecificType=3D"java:com.questerra.webservices.TestObject"/>



</service> 





I don't have any problems in calling the service but am having problems
in parsing the response. If the service returns only one object in the
array and



if I do the following in my client, I don't get any exceptions 



      QName    qnArr         =3D new QName("
http://webservices.questerra.com < http://webservices.questerra.com/> ",
"doTestResponse" ); 

      call.setOperationStyle("wrapped");

      call.registerTypeMapping(TestObject[].class, qnArr,

                    new
org.apache.axis.encoding.ser.ArraySerializerFactory(),

                    new 
org.apache.axis.encoding.ser.ArrayDeserializerFactory());

      call.setOperationName( "doTest" );

      call.setReturnType(qnArr);





But if the service returns more than one object, I am getting an AXIS 
fault as follows:



faultCode:

{ http://schemas.xmlsoap.org/soap/envelope/}Server.userException
<http://schemas.xmlsoap.org/soap/envelope/%7dServer.userException> 
< http://schemas.xmlsoap.org/soap/envelope/%7dServer.userException
