Usage of ParameterMode.OUT with Call.invoke()

[Ambekar Venu <ve...@siemens.com>]

Guys,

I am having issues to retrieve the output
parameters(ParameterMode.OUT/ParameterMode.INOUT) after calling invoke
().

Appreciate if anyone can tell me what I am doing wrong or point me to a
sample code.

Thanks a ton,
Venu.



My code looks as follows:

       Service  service = new Service();
       Call     perCall    = (Call) service.createCall();
       QName    personqn      = new QName( "urn:DBInsertService", "Person"
);

       perCall.registerTypeMapping(Person.class, personqn,
                     new
org.apache.axis.encoding.ser.BeanSerializerFactory(Person.class, personqn),
                     new
org.apache.axis.encoding.ser.BeanDeserializerFactory(Person.class,
personqn));

       perCall.setTargetEndpointAddress( new java.net.URL(endpoint) );
       perCall.setOperationName( new QName("DBInsertService", "insertPerson"
) );
       perCall.addParameter( "person", personqn, ParameterMode.IN );
       perCall.addParameter( "serviceTimes", XMLType.XSD_STRING,
ParameterMode.OUT );
       perCall.setReturnType( XMLType.XSD_BOOLEAN );            // set
return type

      Person dbP = new Person();
      String str = null;     // also tried with new, the result was that
there was no value.

      //   This method sets the result to str;
      boolean l_result = ((Boolean)perCall.invoke(new Object[] {dbP,
str})).booleanValue();

      System.out.println("Output: " + str);    // this line showed up str as
null.

Hi Venu,
I have bit confused with your question. What is the error you exactly get?.
If the string value is null that seems it is correct. Because you set the
String as null and it is an OUT parameter.

Actually the OUT parameter means, in wsdl If a part name appears in only
the output message, it is an out parameter. You check your wsdl whether
the String is an OUT parameter or not.(You can check it in the part
name.If it only occurs in the out message then only it will be a OUT
parameter).

I think it is right when it is an OUT parameter.(String is null). You
better set a value to that String and check it whether it works.

Hope it would help you a bit.
