Answer 1

我查了很久的资料  看到一个说  
javax.xml.transform.TransformerException: Operation not supported.
这个错误是   structs2.0.11与JDK之间的异常
但是我用的是2.3.1与2.3.4 
XML用过多种方式   都是一模一样的  这个错误   晕死啊

Answer 2

..........没人知道吗   大家有人用ssh框架   通信协议是xml的吗   求教啊

Answer 3

而且在同一部电脑上面，两个应用、同一份代码，一个可以正常返回，一个报错！javax.xml.transform.TransformerException: Operation not supported.
