使用AXIS調用WSDL描述的Web服務

首先說一下使用AXIS調用WSDL文件時需要的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文件內容
該實例采用的WSDL文件是使用AXIS創建的Web服務，功能是輸入字符串，返回歡迎語句。對于遠程（其他服務器）的Web服務的調用一直不成功，原本想調用下DictionaryService.wsdl，可是運行時總是返回“ faultString: org.xml.sax.SAXException: Bad envelope tag: definitions”錯誤，實在無奈、、、Hello.jws的內容如下：

<?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

Built on Apr 22, 2006 (06:55:48 PDT)

-->

<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、調用Web服務
據說有三種方法，參見：http://blog.csdn.net/boy_wh520/archive/2007/05/09/1601756.aspx
http://www.ibm.com/developerworks/cn/webservices/ws-startaxis/index.html
這里只介紹一下第一種方法，代碼如下：

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";

//調用過程

Service service = new Service();

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

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

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

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

call.setReturnType(org.apache.axis.encoding.XMLType.XSD_STRING);//設置返回類型

call.setUseSOAPAction( true );

//給方法傳遞參數，并且調用方法

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();

}

@胖胖泡泡
這里是加？WSDL的目的
“?WSDL: Obtaining WSDL for deployed services
When you make a service available using Axis, there is typically a unique URL associated with that service. For JWS files, that URL is simply the path to the JWS file itself. For non-JWS services, this is usually the URL "http://<host>/axis/services/<service-name>".

If you access the service URL in a browser, you'll see a message indicating that the endpoint is an Axis service, and that you should usually access it using SOAP. However, if you tack on "?wsdl" to the end of the URL, Axis will automatically generate a service description for the deployed service, and return it as XML in your browser (try it!). The resulting description may be saved or used as input to proxy-generation, described next. You can give the WSDL-generation URL to your online partners, and they'll be able to use it to access your service with toolkits like .NET, SOAP::Lite, or any other software which supports using WSDL.

You can also generate WSDL files from existing Java classes (see Java2WSDL: Building WSDL from Java).
