Perl 客户端到 JAX-WS java 服务器问题

Question

我有一个发布 Web 服务的 JAX-WS java 服务器

@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;
}

}

和

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

并有一个 perl 客户端

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
007/05/addressing/metadata" xmlns:wsp1_2="http://schemas.xmlsoap.org/ws/2004/09/
policy" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:SOAP-ENC="ht
tp://schemas.xmlsoap.org/soap/encoding/" xmlns:tns="http://operation.calculator/
" xmlns:xsd="http://www.w3.org/2001/XMLSchema"><soapenv:Body><tns:add><c-gensym3
><a xsi:type="xsd:string">test</a></c-gensym3></tns:add></soapenv:Body></soapenv
:Envelope>

这是 Perl 客户端发送的 SOAP 请求。 我假设它构建 SOAP 请求的方式是罪魁祸首。 但如果有人能帮我弄清楚，将不胜感激。 谢谢。

（编辑）这是 JAX-WS 生成的 WSDL：

Answer 1

我遇到了同样的问题。 我使它与以下两个更改一起工作：

1. 将您的 arguments 命名为 XSD ( http://localhost:8080/tomcat/calculator?xsd=1 )
2. 不要使用默认命名空间，而是使用 SOAP 方法（ ns()方法）的命名空间前缀。

示例代码：

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');

您应该知道 SOAP::Simple 在 wsdl 上优于 SOAP::Lite
