WebService调用出现 java.net.UnknownHostException异常？

Question

我用http://172.16.0.65/PowerInfo/WebServiceReportWar/ReportParser访问时出现如下：<?xml version="1.0" encoding="UTF-8" ?>

  </definitions>

Answer 1

难道是address里面错误？
<port binding="tns:ReportParser_REMOTEBinding" name="ReportParser_REMOTEPort">
  <soap:address location="http://statdb:81/PowerInfo/WebServiceReportWar/ReportParser" /> 
 </port>
访问时详细错误如下：

Answer 2

java.net.UnknownHostException
再看一下你的调用URL是http://statdb:81/PowerInfo/WebServiceReportWar/ReportParser
你把这个statdb换成那台机器的IP地址，然后在IE中试一下http://IP地址:81/PowerInfo/WebServiceReportWar/ReportParser?wsdl能不能出东西，如果可以出，那就说明可以了。

Answer 3

看看你的几个JAR包加全了没有，特别是远程访问用到的jaxrpc.jar等等
