我有一个WSDL和一些模式文件,我用它来生成一个JAX-WS Web服务客户端。当我尝试获取客户端的实例时,我得到了这个堆栈跟踪:
Caused by: java.lang.IllegalArgumentException: The specified prefix was null. at com.ibm.xml.xlxp.api.stax.msg.StAXMessageProvider.throwIllegalArgumentException(StAXMessageProvider.java:42) at com.ibm.xml.xlxp.api.stax.XMLStreamReaderImpl.getNamespaceURI(XMLStreamReaderImpl.java:721) at com.ibm.xml.xlxp.api.stax.XMLInputFactoryImpl$XMLStreamReaderProxy.getNamespaceURI(XMLInputFactoryImpl.java:212) at com.sun.xml.internal.ws.util.xml.XMLStreamReaderFilter.getNamespaceURI(XMLStreamReaderFilter.java:242) at com.sun.xml.internal.ws.wsdl.parser.ParserUtil.getQName(ParserUtil.java:78) at com.sun.xml.internal.ws.wsdl.parser.RuntimeWSDLParser.parsePortTypeOperationInput(RuntimeWSDLParser.java:721) at com.sun.xml.internal.ws.wsdl.parser.RuntimeWSDLParser.parsePortTypeOperation(RuntimeWSDLParser.java:694) at com.sun.xml.internal.ws.wsdl.parser.RuntimeWSDLParser.parsePortType(RuntimeWSDLParser.java:668) at com.sun.xml.internal.ws.wsdl.parser.RuntimeWSDLParser.parseWSDL(RuntimeWSDLParser.java:305) at com.sun.xml.internal.ws.wsdl.parser.RuntimeWSDLParser.parse(RuntimeWSDLParser.java:136) at com.sun.xml.internal.ws.client.WSServiceDelegate.parseWSDL(WSServiceDelegate.java:227) at com.sun.xml.internal.ws.client.WSServiceDelegate.(WSServiceDelegate.java:190) at com.sun.xml.internal.ws.client.WSServiceDelegate.(WSServiceDelegate.java:160) at com.sun.xml.internal.ws.spi.ProviderImpl.createServiceDelegate(ProviderImpl.java:92) at javax.xml.ws.Service.(Service.java:67) ...
对于我来说,看起来很像Service类试图将WSDL解析为其初始化的一部分,然后因为某些前缀为null而失败。行at com.sun.xml.internal.ws.wsdl.parser.ParserUtil.getQName(ParserUtil.java:78)
表明它在解析QName时遇到问题。创建服务时,QName设置如下:
new QName("http://www.mycompany.ca/some/schema/MyService", "MyService")
但错误信息不太清楚。是"MyService"
之前需要的前缀,还是必需的WSDL更改(我不是WSDL所有者,因此很难将更改推送到其他团队)。
(环境是WAS 7.0的RAD 7.5)
答案 0 :(得分:1)
如果检查堆栈跟踪的详细信息,您会注意到问题在于WSDL中端口类型操作输入的名称:
<wsdl:definitions .... >
<wsdl:portType .... >
<wsdl:operation>
<wsdl:input message="qname"/> <--- your problem is here
</wsdl:operation>
</wsdl:portType >
</wsdl:definitions>
