看看两段简单的JAVA代码,我们用它作为WSDL的服务实现代码:
//CatDTO.java
public class CatDTO
{
  private long id;
  private String name;
  public long getId()
  {
    return id;
  }
  public String getName()
  {
    return name;
  }
  public void setId(long id)
  {
    this.id = id;
  }
  public void setName(String name)
  {
    this.name = name;
  }
}
//Test.java
public class Test
{
  public String echo(CatDTO cd){
    return "Hello " + cd.getName();
  }
}
然后看看用它导出的WSDL:

   //与实现进行绑定,这里用SOAP方式

      <wsdl:operation name="echo">

         </wsdl:output>

      </wsdl:operation>

   </wsdl:binding>
  //用于发布服务

   <wsdl:service name="TestService">

         <wsdlsoap:address location="http://localhost:8080/hongsoft/services/Test"/>

      </wsdl:port>

   </wsdl:service>

</wsdl:definitions>
