Re: Tuscany自动生成的WebService的WSDL文件格式有问题,会自动将wsdl:fault中的message属性前加入了错误的namespace

[DT]

修正一下,具体版本是1.6.2.

在 2012年7月17日星期二UTC+8下午2时46分57秒，DT写道：

本人使用Tsucany SCA 1.6的版本:

最近在测试Tuscany生成的WSDL是否可用于生成客户端,结果发现WSDL中对于Exception的处理存在问题:

这是我写的一个简单的服务通过Tuscany自动生成的WSDL文件,请大家注意加粗加下划线的部分:

使用上述的WSDL文件,通过下列命令生成客户端,会出错:

>>>>通过将上文中的红色中的粗体带下划线的去掉ns4改为

<wsdl:fault name="Exception" message="Exception"> 

即可正确生成客户端.

通过观察,发现这个message应该是指向上面的<message />的定义,而上面的定义没有在ns4的名字空间下,导致寻找出错.

感觉这个问题应该是个BUG,有人发现同样的问题吗?如何解决?

请高手赐教,谢谢.

另外:如果使用Tuscany作为客户端调用自己生成的WebService,不会出错.(应该是直接跳过了WSDL这个环节了).

此问题是Tuscany的BUG，已在1.6.x的trunk中解决了，通过同步WSDL部分的代码可以解决此问题。

 It was reported as TUSCANY-3778 and it was fixed
in the 1.x trunk under revision r1036533.
