先写一个java的class:AwbModel(相当于要在web service中传输的实体对象)
package webservicesample;
public class AwbModel {
private String _a1 = "_a1";
public String getA1() {
return _a1;
}
public void setA1(String value) {
this._a1 = value;
}
private String _A2 = "_A2";
public String getA2() {
return _A2;
}
public void setA2(String value) {
this._A2 = value;
}
private String a3 = "a3";
public String getA3() {
return a3;
}
public void setA3(String value) {
this.a3 = value;
}
private String A4 = "A4";
public String getA4() {
return A4;
}
public void setA4(String value) {
this.A4 = value;
}
private String A5 = "A5";
public String getA5() {
return A5;
}
private String A6 = "A6";
public void setA6(String value) {
this.A6 = value;
}
public String A7 = "A7";
//private String _a8="a8";
public String get_a8(){
//return _a8;
return "";
}
public void set_a8(String value){
//this._a8=value;
}
public String sayHelloA(){
return "Hello!";
}
}然后再写一个Awb类(相当于web service的接口+实现)
package webservicesample;
public class Awb {
public AwbModel GetAwbModelByNo() {
AwbModel a = new AwbModel();
a.setA1("a1_new");
return a;
}
private String _b1 = "_b1";
public String getB1() {
return _b1;
}
public void setB1(String value) {
this._b1 = value;
}
private String _B2 = "_B2";
public String getB2() {
return _B2;
}
public void setB2(String value) {
this._B2 = value;
}
private String b3 = "b3";
public String getB3() {
return b3;
}
public void setB3(String value) {
this.b3 = value;
}
private String B4 = "B4";
public String getB4() {
return B4;
}
public void setB4(String value) {
this.B4 = value;
}
private String B5 = "B5";
public String getB5() {
return B5;
}
private String B6 = "B6";
public void setB6(String value) {
this.B6 = value;
}
public String B7 = "B7";
public String sayHelloB() {
return "Hello B!";
}
}jBuilder2006环境下，封装成web service发布到weblogic后，WSDL的内容见下图:
注意：因为A5只有get方法，A6只有set方法，最终生成的WSDL自动去掉了这二个“属性”(后面在用c#调用该java web Service时，能看到这将会生成真正意义上的.net property)，自定义的其它方法(比如sayHelloA)被丢弃(即：这类方法没有自动序列化)，同时比较有意思的是"_a8"，AwbModel.java里只定义了set_a8(String value),get_a8()方法，根本没有声明_a8的private变量，但是java自动视为已经存在“_a8”的私有成员；此外直接声明的public变量，WSDL里不改变大小写，仍然还是A7；而其它的setXXX,getXXX方法，最终一律去掉set/get后，将首字母小写，即xXX。
类似vs.net里添加服务引用后，会自动生成xxxClient、xxxChannel、代理类等客户端调用代码一样，make之后，jBuilder也会生成客户端代码示例包Awb_Client.jar，解压后看下AwbModel.java的内容:

}
}与WSDL里看到的基本一致，不过跟原始的AwbModel.java相比，还是有一些有趣的小变化：原始AwbModel.java里定义的私成成员，一律变成了小写，而自动添加的"_A8"却又是大写。
下面看看用java如何调用web service：
随便新建一个java项目，把jBuilder自动生成的Awb_client.jar包引用进来
package jmyang.web_service_call;
import webservicesample.generated.*;
import java.io.IOException;
import javax.xml.rpc.ServiceException;
public class wsCallDemo {
public void callService() {
String wsdlUrl = "http://127.0.0.1:7001/MyWebService/Awb?WSDL";
try {
Awb service = new Awb_Impl(wsdlUrl);
AwbPort port = service.getAwbPort();
AwbModel result = port.getAwbModelByNo();
System.out.println("awbmodel.a1=" + result.getA1());
} catch (IOException e) {
e.printStackTrace();
} catch (ServiceException e2) {
e2.printStackTrace();
}
}
}这样就能调用了.
.net当然也能调用java写的web service，在vs.net里添加服务引用，服务地址输入:http://127.0.0.1:7001/MyWebService/Awb?WSDL vs.net会象添加wcf/asmx服务引用一样，自动生成代理类等其它代码，看看自动生成的AwbModel类

if ((propertyChanged != null)) {
propertyChanged(this, new System.ComponentModel.PropertyChangedEventArgs(propertyName));
}
}
}可以发现，刚才截图里的a1、a2、a3、a4、A7、_a8全都以属性(property)的方式出现了。
c#的调用代码还是一如继往的简单：
using (YJM.AwbPortClient client = new AwbPortClient())
{
var model = client.GetAwbModelByNo();
Console.WriteLine("a1=" + model.a1);
Console.WriteLine("a2=" + model.a2);
Console.WriteLine("a3=" + model.a3);
Console.WriteLine("a4=" + model.a4);
Console.WriteLine("A7=" + model.A7);
Console.WriteLine("_a8=" + model._a8);
Console.Read();
