使用AXIS调用WSDL描述的Web服务

首先说一下使用AXIS调用WSDL文件时需要的JAR包：
（1）axis    其中包括axis.jar、axis-ant.jar、commons-discovery-0.2.jar、commons-logging-1.0.4.jar、jaxrpc.jar、log4j-1.2.8.jar、log4j.properties、saaj.jar、wsdl4j-1.5.1.jar。http://www.apache.org/dyn/closer.cgi/ws/axis/
（2）javamail    mail.jar。http://java.sun.com/products/javamail/
（3）jaf    activation.jar。http://java.sun.com/javase/technologies/desktop/javabeans/jaf/downloads/index.html
一、WSDL文件内容
该实例采用的WSDL文件是使用AXIS创建的Web服务，功能是输入字符串，返回欢迎语句。对于远程（其他服务器）的Web服务的调用一直不成功，原本想调用下DictionaryService.wsdl，可是运行时总是返回“ faultString: org.xml.sax.SAXException: Bad envelope tag: definitions”错误，实在无奈、、、Hello.jws的内容如下：

<?xml version="1.0" encoding="UTF-8" ?>

<wsdl:definitions targetNamespace="http://localhost:8080/axis/Hello.jws" xmlns:apachesoap="http://xml.apache.org/xml-soap" xmlns:impl="http://localhost:8080/axis/Hello.jws" xmlns:intf="http://localhost:8080/axis/Hello.jws" xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:wsdlsoap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:xsd="http://www.w3.org/2001/XMLSchema">

WSDL created by Apache Axis version: 1.4

-->

<wsdl:message name="helloResponse">

<wsdl:part name="helloReturn" type="xsd:string" />

</wsdl:message>

<wsdl:message name="helloRequest">

<wsdl:part name="name" type="xsd:string" />

</wsdl:message>

<wsdl:portType name="Hello">

<wsdl:operation name="hello" parameterOrder="name">

<wsdl:input message="impl:helloRequest" name="helloRequest" />

<wsdl:output message="impl:helloResponse" name="helloResponse" />

</wsdl:operation>

</wsdl:portType>

<wsdl:binding name="HelloSoapBinding" type="impl:Hello">

<wsdlsoap:binding style="rpc" transport="http://schemas.xmlsoap.org/soap/http" />

<wsdl:operation name="hello">

<wsdlsoap:operation soapAction="" />

<wsdl:input name="helloRequest">

<wsdlsoap:body encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" namespace="http://DefaultNamespace" use="encoded" />

</wsdl:input>

<wsdl:output name="helloResponse">

<wsdlsoap:body encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" namespace="http://localhost:8080/axis/Hello.jws" use="encoded" />

</wsdl:output>

</wsdl:operation>

</wsdl:binding>

<wsdl:service name="HelloService">

<wsdl:port binding="impl:HelloSoapBinding" name="Hello">

<wsdlsoap:address location="http://localhost:8080/axis/Hello.jws" />

</wsdl:port>

</wsdl:service>

</wsdl:definitions>

二、调用Web服务
据说有三种方法，参见：http://blog.csdn.net/boy_wh520/archive/2007/05/09/1601756.aspx
http://www.ibm.com/developerworks/cn/webservices/ws-startaxis/index.html
这里只介绍一下第一种方法，代码如下：

package wsdl;

import org.apache.axis.client.Call;

import org.apache.axis.client.Service;

public class CallService {

public static void main(String[] args) {

try {

String endpoint = "http://localhost:8080/axis/Hello.jws";

//调用过程

Service service = new Service();

Call call = (Call) service.createCall();

call.setTargetEndpointAddress(new java.net.URL(endpoint));

call.setOperationName("hello");//WSDL里面描述的操作名称

call.addParameter("helloRequest", org.apache.axis.encoding.XMLType.XSD_STRING, javax.xml.rpc.ParameterMode.IN);//操作的参数

call.setReturnType(org.apache.axis.encoding.XMLType.XSD_STRING);//设置返回类型

call.setUseSOAPAction( true );

//给方法传递参数，并且调用方法

String temp = "Tom";

Object[] obj = new Object[]{temp};

String result = (String)call.invoke(obj);

System.out.println("Result is : "+result);

} catch (Exception e) {

e.printStackTrace();

}
