Websphere 7中的JAX-WS客户端失败，出现java.io.UnsupportedEncodingException：text / xml

Question

在IIS中部署AXIS2 Web服务。使用wsdl我生成了JAX-WS客户端。如果我单独使用它，即使用Oracle JDK，它可以正常工作。

我必须从我在websphere 7中部署的应用程序中调用webservice。因此，我在我的应用程序中包含了jax-ws生成的客户端（作为jar）。当应用程序调用webservice时，它失败并出现java.io.UnsupportedEncodingException：text / xml异常。 Websphere 7将与axis2相关的jar文件用于jax-ws。

编辑：更多信息..网络服务正在返回响应。似乎websphere无法处理响应，即问题中指定的异常失败。

请帮忙。

异常是因为无效的响应标头*text/xml;charset:UTF-8*. It supposed to be *text/xml;charset=UTF-8*。 IBM JDK在解析时更严格，而Oracle JDK则不然。希望这有助于在调用任何外部Web服务时，如果任何人在Websphere应用程序服务器中遇到类似于“java.io.UnsupportedEncodingException：text / xml”的异常。
