开发flex错误篇-Couldn't establish a connection to

现在在做flex和spring的集成,在写好了工厂类,配置好服务以后再启动服务使用服务是提示如下错误

[RPC Fault faultString="[MessagingError message='Destination 'product' either does not exist or the destination has no channels defined (and the application does not define any default channels.)']" faultCode="InvokeFailed" faultDetail="Couldn't establish a connection to 'product'"]

分析大体意思就是连接不到服务器上。

问题描述:

1、缓存数据问题,如果编译出现问题,第二次不会发生变异,可以采用project -> clean...来清除所有的编译生成的文件

2、问题点发现就是在flex编译的时候没有找到services-config.xml,当找到这个文件以后,因为里面包含了一个factories标签,发现错误,不进行编译

3、在配置的工程编译属性中添加-context-root=/flex工程出错,不进行编译,编译完成的context-root名称为默认的工程名称,通过修改工程目录下的.flexproperties文件修改就可以。

4、可以编译,可以运行代码,但是运行中出现如下错误:
