Axis2 Quick Start Guide
It introduce many methods here, I just read them and find that axis2.war is useful. So I copy the code from
F:\book\opensource\axis2\axis2-1.5.1-src\axis2-1.5.1\modules\webapp
and build a project easyaixs to be a management system of my own axis2 webservice.
my ivy.xml will be like this:
<ivy-module version="2.0">
<info organisation="sccl" module="swak" />
<configurations>
<conf name="release" />
</configurations>
<publications>
<artifact name="common" />
<artifact name="client" />
</publications>
<dependencies>
<!-- commons -->
<dependency org="commons-logging" name="commons-logging" rev="1.1.1" />
<dependency org="commons-fileupload" name="commons-fileupload" rev="1.1.1" />
<dependency org="commons-httpclient" name="commons-httpclient" rev="3.1" />
<dependency org="commons-io" name="commons-io" rev="1.4" />
<dependency org="commons-codec" name="commons-codec" rev="1.4" />
<!-- axis2 -->
<dependency org="org/apache/axis2" name="axis2-kernel" rev="1.5.1" />
<dependency org="org/apache/axis2" name="axis2-adb" rev="1.5.1" />
<dependency org="org/apache/axis2" name="axis2-jaxws" rev="1.5.1" />
<dependency org="org/apache/axis2" name="axis2-transport-http" rev="1.5.1" />
<dependency org="org/apache/axis2" name="axis2-transport-local" rev="1.5.1" />
<dependency org="wsdl4j" name="wsdl4j" rev="1.6.2" />
<dependency org="org/apache/ws/commons/schema" name="XmlSchema" rev="1.4.3" />
<dependency org="org/apache/ws/commons/axiom" name="axiom-api" rev="1.2.8" />
<dependency org="org/apache/ws/commons/axiom" name="axiom-impl" rev="1.2.8" />
<dependency org="org/apache/neethi" name="neethi" rev="2.0.4" />
<dependency org="javax/mail" name="mail" rev="1.4" />
<dependency org="org/apache/woden" name="woden-api" rev="1.0M8" />
<dependency org="org/apache/httpcomponents" name="httpcore" rev="4.0" />
<dependency org="org/codehaus/woodstox" name="wstx-asl" rev="3.2.4" />
</dependencies>
</ivy-module>
And the username and password of the admin console is configured in axis2.xml with location WEB-INF/conf/axis2.xml, and it will be admin/axis2 in default situation.
After that I just follow the article
http://ws.apache.org/axis2/1_5_1/pojoguide.html
POJO Web Services using Apache Axis2
to build a webservice example.
撰写一个简单的POJO,Weather.java如下：
package com.sillycat.axis2.weather.models;
public class Weather {
float temperature;
String forecast;
boolean rain;
float howMuchRain;
...getter and setter snip...
}
一个简单的service服务类WeatherService.java如下：
package com.sillycat.axis2.weather.services;
import java.util.Date;
import com.sillycat.axis2.weather.models.Weather;
public class WeatherService {
Weather weather;
public void setWeather(Weather weather) {
this.weather = weather;
}
public Weather getWeather() {
return this.weather;
}
public void echoTheWeather() {
System.out.println("Today=" + new Date() + " temperature="
+ weather.getTemperature());
}
}
配置文件services.xml如下：
<service name="WeatherService" scope="application">
<description>
Weather POJO Service
</description>
<messageReceivers>
<messageReceiver mep="http://www.w3.org/2004/08/wsdl/in-only"
/>
<messageReceiver mep="http://www.w3.org/2004/08/wsdl/in-out"
/>
</messageReceivers>
<parameter name="ServiceClass">com.sillycat.axis2.weather.services.WeatherService
</parameter>
</service>
打包脚本也准备好了，build.properties如下：
service.name=WeatherService
service.version=1.0
catalina.home=E:\\tool/apache-tomcat-6.0.20/
ant.encoding=UTF-8
java.level=1.5
compile.debug=true
compile.deprecation=true
compile.optimize=true
axis.home=E:\\work/easyaxis/
build.xml脚本如下：

打包后，直接将打好的Weather-1.0.saar拷贝到easyaxis下面的services目录了，启动easyaxis就发布了服务了。同时，我还参考示例写了个测试类WeatherServiceTest.java：
package com.sillycat.axis2.weather;
import javax.xml.namespace.QName;
import org.apache.axis2.AxisFault;
import org.apache.axis2.addressing.EndpointReference;
import org.apache.axis2.client.Options;
import org.apache.axis2.rpc.client.RPCServiceClient;
import com.sillycat.axis2.weather.models.Weather;
public class WeatherServiceTest {
@SuppressWarnings("unchecked")
public static void main(String[] args1) throws AxisFault {
RPCServiceClient serviceClient = new RPCServiceClient();
Options options = serviceClient.getOptions();
// EndpointReference targetEPR = new EndpointReference(
// "http://localhost:8080/easyaxis/services/WeatherService");
EndpointReference targetEPR = new EndpointReference(
"http://192.168.1.127:8080/easyaxis/services/WeatherService");
options.setTo(targetEPR);
// Setting the weather
QName opSetWeather = new QName(
"http://services.weather.axis2.sillycat.com", "setWeather");
Weather w = new Weather();
w.setTemperature((float) 39.3);
w.setForecast("Cloudy with showers");
w.setRain(true);
w.setHowMuchRain((float) 4.5);
Object[] opSetWeatherArgs = new Object[] { w };
serviceClient.invokeRobust(opSetWeather, opSetWeatherArgs);
// Getting the weather
QName opGetWeather = new QName(
"http://services.weather.axis2.sillycat.com", "getWeather");
Object[] opGetWeatherArgs = new Object[] {};
Class[] returnTypes = new Class[] { Weather.class };
Object[] response = serviceClient.invokeBlocking(opGetWeather,
opGetWeatherArgs, returnTypes);
Weather result = (Weather) response[0];
if (result == null) {
System.out.println("Weather didn't initialize!");
return;
}
// Displaying the result
System.out.println("Temperature : "
+ result.getTemperature());
System.out.println("Forecast : "
+ result.getForecast());
System.out.println("Rain : " + result.isRain());
System.out.println("How much rain (in inches) : "
+ result.getHowMuchRain());
}
}
由于这个测试类，还必须导入写jar包才行，ivy.xml如下：
<dependencies>
<!-- commons -->
<dependency org="commons-logging" name="commons-logging" rev="1.1.1" />
<dependency org="commons-httpclient" name="commons-httpclient" rev="3.1" />
<dependency org="commons-codec" name="commons-codec" rev="1.4" />
<!-- axis2 -->
<dependency org="org/apache/axis2" name="axis2-kernel" rev="1.5.1" />
<dependency org="org/apache/axis2" name="axis2-adb" rev="1.5.1" />
<dependency org="org/apache/ws/commons/axiom" name="axiom-api" rev="1.2.8" />
<dependency org="org/apache/ws/commons/axiom" name="axiom-impl" rev="1.2.8" />
<dependency org="wsdl4j" name="wsdl4j" rev="1.6.2" />
<dependency org="org/apache/ws/commons/schema" name="XmlSchema" rev="1.4.3" />
<dependency org="org/apache/neethi" name="neethi" rev="2.0.4" />
<dependency org="org/apache/axis2" name="axis2-transport-local" rev="1.5.1" />
<dependency org="org/apache/axis2" name="axis2-transport-http" rev="1.5.1" />
<dependency org="javax/mail" name="mail" rev="1.4" />
<dependency org="org/apache/httpcomponents" name="httpcore" rev="4.0" />
</dependencies>
这也是参考官方文档做了练习，以后要使用，可能还有很多细节要看。
问题一：
我用写的Client访问WS服务的时候。
出错信息：
信息: Unable to sendViaPost to url[http://localhost:8080/easyaxis/services/WeatherService]
org.apache.axis2.AxisFault: Transport error: 404 Error: Not Found
at org.apache.axis2.transport.http.HTTPSender.handleResponse(HTTPSender.java:310)
解决方案：
难道我写错了，命名wsdl文件都可以访问哒，看到404，怀疑是不是网络问题，修改为127.0.0.1还是不行，非要改成自己的IP才行。
// EndpointReference targetEPR = new EndpointReference(
// "http://localhost:8080/easyaxis/services/WeatherService");
EndpointReference targetEPR = new EndpointReference(
"http://192.168.1.127:8080/easyaxis/services/WeatherService");
问题二：
直接访问WSDL文件http://localhost:8080/easyaxis/services/Version?wsdl，成功，访问
http://localhost:8080/easyaxis/services/Version 却报错。
出错信息：
严重: The endpoint reference (EPR) for the Operation not found is /easyaxis/services/Version and the WSA Action = null
org.apache.axis2.AxisFault: The endpoint reference (EPR) for the Operation not found is /easyaxis/services/Version and the WSA Action = null
at org.apache.axis2.engine.DispatchPhase.checkPostConditions(DispatchPhase.java:89)
解决方案：
最先以为是自己的问题，后来发现axis2给的例子都不得行，原来调用的时候必须加上方法名作为参数，比如要这么访问：
http://localhost:8080/easyaxis/services/Version/getVersion
