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

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。

1.3 Dos进行webService发布时报错

  • 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);
