Subject Sending array object with Axis
Date Mon, 14 Feb 2005 01:42:07 GMT
Ok, my problem is I'm accessing a web service with
apache axis and when I try to send an array ob object
to the service only the first element of the array is
received. I'm using JBuilder to develop the client,
and the web service is written in PHP using NuSOAP.
The service is simple it just counts the number of
elements in the array  and returns the amount. Here's
the WSDL:
<?xml version="1.0" encoding="ISO-8859-1"?>

And here is my code that I'm using to test the
service:
package soapobjectarraytest;

import java.net.URL;

import nu.mine.homegrown.TestService.*;
import org.apache.axis.*;

public class ObjectTest {
    public static void main(String[] args) {
        TestFunctions service = new
TestFunctionsLocator();
        Person p1, p2, p3;

        try {

            TestFunctionsBindingStub binding = new
                                              
TestFunctionsBindingStub(new URL(
                   
service.getTestFunctionsPortAddress()), service);
            p1 = new Person(12, "Bart", "Simpson",
"bart@yahoo.com");
            p2 = new Person(14, "Marge", "Simpson",
"marge@hotmail.com");
            p3 = new Person(22, "Harry", "Potter",
"harry@gmail.com");
            Person[] pers = {p1, p2, p3};

            System.out.println("Number of objects
recieved at server: " + binding.countObjects(pers));
        } catch (AxisFault e) {
            System.err.println("Caught SOAPException
(" + e.getFaultCode() +
                               "): " +
e.getMessage());
        } catch (Exception ex) {
            ex.getMessage();
            ex.printStackTrace();
        }
    }
}
