Perl client to JAX-WS java server issue

Question

I have a JAX-WS java server which publishes a web-service

@WebService(endpointInterface="calculator.operation.Calculator")
public class CalculatorWs implements Calculator{

public String[] add(String a) {

    System.out.println(a);

    String[] test = {"this", "that"};
    System.out.println(test);
    return test;
}

}

and

@WebService
@SOAPBinding(style=SOAPBinding.Style.DOCUMENT)
public interface Calculator {
    String[] add(String a);
}

and have a perl client

use SOAP::Lite +trace => 'all';
$SOAP::Constants::PREFIX_ENV = 'soapenv';
$SOAP::Constants::PREFIX_ENC = "SOAP-ENC";
my $soap = SOAP::Lite
->service('http://localhost:8080/tomcat/calculator?wsdl')
->soapversion('1.1');
my $var = {'a' => "test"};
my $result = $soap -> add($var);

The problem I'm having is that the Java server does not receive the arguments passed by the Perl client, although the value returned by the Java server is received and recognized by the client.

<?xml version="1.0" encoding="UTF-8"?>
<soapenv:Envelope xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd" soapenv:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" xmlns:wsp="http://www.w3.org/ns/ws-policy" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:wsam="http://www.w3.org/2

><a xsi:type="xsd:string">test</a></c-gensym3></tns:add></soapenv:Body></soapenv
:Envelope>

this is the SOAP request sent by the Perl client. Im assuming the way its building the SOAP request is to blame . But if anyone could help me figure it out, would be greatly appreciated. Thanks.

(edit) Here is the WSDL generated by JAX-WS:

Answer 1

I was having the same problem. I made it work with the following two changes:

1. Name your arguments as in the XSD (http://localhost:8080/tomcat/calculator?xsd=1)
2. Don't use the default namespace, but a namespace prefix for the SOAP method (ns() method).

Example code:

my $soap = SOAP::Lite                                             
  -> proxy('http://localhost:8080/tomcat/calculator')
  -> ns   ('http://operation.calculator/');

my $response = $soap->call('add', SOAP::Data->name( arg0 => 'Peter Pan'));

Answer 2

Showing the java function is great for java programmers, you need to show the WSDL or sample SOAP (read XML) invocation ... my guess, all you need

my $result = $soap -> add( 'test');

You should know SOAP::Simple is better at wsdl than SOAP::Lite
