【WebService异常分析】

1. Axis1.x框架的WebService

1.1 在生成server-config.wsdd时报错

命令：java -cp %AXISCLASSPATH% org.apache.axis.client.AdminClient deploy.wsdd
报错内容：

D:\Tomcat\apache-tomcat-6.0.43\webapps\DemoWebService\WEB-INF>java -cp %AXISCLASSPATH% org.apache.axis.client.AdminClien

}}}

如我的deploy.wsdd文件如下：

<?xml version="1.0" encoding="UTF-8"?>
<deployment xmlns="http://xml.apache.org/axis/wsdd/"xmlns:java="http://xml.apache.org/axis/wsdd/providers/java"><service name="HelloWorldWSDD" provider="java:RPC"><parameter name="className" value="cn.hw.ws.HelloWorldWSDD" /><!-- 代表所有的方法都暴露 --><parameter name="allowedMethods" value="*" /><parameter name="scope" value="request" /></service>
</deployment>

解决办法
dos命令到WEB-INF下，命令改为：java -cp %AXISCLASSPATH% org.apache.axis.client.AdminClient -l http://localhost:8181/axis/services/HelloWorldWSDD deploy.wsdd
参考文档： webservice Axis发布deploy.wsdd出错， {http://xml.apache.org/axis/}stackTrace:java.net.ConnectException: Coction refused: connect

1.2 将不带报名的类HelloWorldService放到tomcat的axis工程中，在浏览器中访问，点击Click to see the WSDL 报错

报错内容

AXIS error
Sorry, something seems to have gone wrong… here are the details:

……

原因分析
在tomcat中的axis工程原来部署过HelloWorldWSDD类，虽然该类在tomcat中删除了，但是其发布用的配置文件“server-config.wsdd”还在tomcat中。删除该文件，然后重启tomcat，在tomcat重启的过程中会报出”Unable to find config file. Creating new servlet engine config file: /WEB-INF/server-config.wsdd“，应该是tomcat的某个文件中有记录，所以重启时会显示该记录，但是并不影响其他类HelloWorldService的发布。

错误原因分析
我在编写deployComplex.wsdd时，里面含有中文注释。将该中文注释删除，然后重新发布即可。可以将deployComplex.wsdd中的encoding=”UTF-8”改为encoding=”gbk”。

原因分析
客户端代码中url地址错误，如下面代码中的url与发布的服务地址不符合

String url = "http://localhost:8080/AxisWebService/services/UploadFile";
Service service = new Service();
Call call = (Call) service.createCall();
call.setTargetEndpointAddress(url);
