[求助]问两个SAAJ编程的问题，高手们帮忙－－急

KevinChen · 发表于 2006-7-21 16:18:23

1.怎么在<soapenv:Envelope>元素里添加而外的namespace，用SAAJ的API生成SOAP包，<soapenv:Envelope>里只有一个默认的namespace

2.怎么设置元素不同类型的值，我在api中只看到addTextNode()的这个方法，可是这个方法添加的只是String类型的，怎么可以添加比如boolean，以及自己定义的一些类型？

问题很急，希望大家帮忙
毕业上班的第一个任务，希望能够完成的出色点

SAAJ是什么？
ＳＯＡＰ？
呵呵。
正好我最近也有一个SOAP的东西在弄。
不知道楼上用的是啥工具？
我目前了解了两种：
Perl的SOAP:

ite和java的axis.

就是SOAP啦，我想自己手动写一个客户端程序，连接到已经规定好服务端上
以Google的API为例，我想不用Google的api，自己手动写一个满足google的wsdl文件规定的客户端程序，但是编写的时候就遇到上面的两个问题了，第一问题解决了一半，第二个问题毫无头绪，我把SAAJ的的API看了遍，但是就是没有看到怎么样添加不同类型的元素值，就看到了一个addTextNode()，但是google的wsdl里规定的还有boolean类型，还有int类型，不知道要怎么做，如果只用addTextNode()方法发出去，收到的就是类型错误的<soapfault>代码的回复

顺便贴一下我写的代码，很糙就是了

import javax.xml.soap.*;
import javax.xml.messaging.*;
import javax.xml.namespace.QName;
public class GoogleSearchClient{
public static final String DEFAULT_HOST_URL = "http://api.google.com/search/beta2";
public static void main(String[] args){
try{
// Create the connection
SOAPConnectionFactory scf = SOAPConnectionFactory.newInstance();
SOAPConnection connection = scf.createConnection();
// create a empty context message
MessageFactory mf = MessageFactory.newInstance();
SOAPMessage message = mf.createMessage();
// create objects for the message
SOAPPart soapPart = message.getSOAPPart();
SOAPEnvelope envelope = soapPart.getEnvelope();
SOAPBody body = envelope.getBody();
//QName qname = new QName("urn:GoogleSearch","GoogleSearchPort");
Name name = envelope.createName("doGoogleSearch","urn:GoogleSearch","GoogleSearchPort");
SOAPElement bodyElement = body.addChildElement(name);
// add message context of doGoogleSearch
bodyElement.addChildElement("key").addTextNode("FKwUhSBQFHItwJcf5LxGsjKMyhC0cggp");
bodyElement.addChildElement("q").addTextNode("Linux");
bodyElement.addChildElement("start").addTextNode("0");
bodyElement.addChildElement("maxResults").addTextNode("10");
bodyElement.addChildElement("filter").addTextNode("false");
bodyElement.addChildElement("restrict");
bodyElement.addChildElement("safeSearch").addTextNode("false");
bodyElement.addChildElement("lr");
bodyElement.addChildElement("ie");
bodyElement.addChildElement("oe");
message.saveChanges();
// Output the message
System.out.println("message:");
message.writeTo(System.out);
System.out.println();
URLEndpoint url = new URLEndpoint(DEFAULT_HOST_URL);
SOAPMessage reply = connection.call(message, url);
// check the response
System.out.println("the response");
reply.writeTo(System.out);
connection.close();
}catch(Throwable e){
e.printStackTrace();
}
}
}

还有就是google的wsdl文件,http://api.google.com/GoogleSearch.wsdl

我的目的比较简单，我只想完成符合wsdl文档规定的客户端
可以发送soap包，然后收到回复就可以了
不必要完成服务端的配置及实现

顺带说一下：我自己学习的时候用的是apache axis
我是刚开始学Web Service，概念上还是很不清楚，经常一头雾水

解决了，我namespace在编写的时候写错了位置了，解决了，呼呼，任务快完成了
