Java WS不支持DencodingException

当我尝试使用运行在JBoss4.0.2上的Web服务时，它返回以下错误

四处搜索，这似乎是JAX-WS的一个问题。这里有几个bug报告支持这一结论

很难说JBoss包含了哪个版本的JAX-WS，因为它实际上是AXIS2包的一部分，但我最好的猜测是它是1.4版。JBoss是否有解决此问题的方法，或者它是否需要不同版本的JAX-WS？我对JBoss一点也不熟悉，所以我不知道是否可以用一个更新的版本来替换JAR。

如何通过http post使用部署在JBoss中的web服务。将xml和内容类型作为http头传入。我有一个类似的问题。但是我用的是Spring，你现在有解决方案吗？
