Axis2 1.3 POJO guide里的例子通过Axis2的Service Achiever插件发布，调用服务问题！

axis2 bin包里的源码使用ant生成的arr发布使用客户端调用服务正常，输出：
Temperature               : 39.3
Forecast                  : Cloudy with showers
Rain                      : true
How much rain (in inches) : 4.5
而使用Axis2的Service Achiever插件生成的arr发布调用失败，输出：

    String forecast;
    boolean rain;
