当我尝试从部署到 WebSphere 7.0 的类调用 WebService(HP-Service Manager，如果它有帮助的话)时出现错误。当我调用它时，相同的代码起作用从 JUnit 代码...
WSDL的片段是:
<definitions targetNamespace="http://schemas.hp.com/SM/7"
xmlns="http://schemas.xmlsoap.org/wsdl/"
xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://schemas.xmlsoap.org/wsdl/ http://schemas.xmlsoap.org/wsdl/">
我认为 xmlns:xsi 总是被 XML 解析器识别，所以我不明白这个错误。为什么在 WebSphere 上会出现此类错误，而在 JUnit 中使用 com.ibm.ws.webservices.thinclient 启动代码时却不会出现？
适当的 StackTrace 片段是:

最佳答案
错误的意思正是它所说的:xsi 前缀没有命名空间声明。
XML 解析器并不具备此 namespace 的内置知识。需要声明它以使文档命名空间格式正确。
关于java - SAX 解析异常 : The prefix "xsi" for attribute "xsi:schemaLocation" is not bound，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/16690404/
