axis2开发笔记-消息监控

  在调试或者定位问题的时候通常需要看到传递的具体消息内容，得益于axis2良好的架构设计，首先想到开发一个log模块插到axis的消息处理流中，但事实上axis2已经提供了这个模块，用了一下感觉挺好用，但为性能考虑默认情况下这个模块是没有装载的，下面介绍一下装载配置过程（以tomcat容器在本机安装为例）。

1.因为使用了applet进行显示，首先要安装applet
将<CATALINA_HOME>/webapps/axis2/WEB-INF/lib/soapmonitor-1.3.jar解压放到<CATALINA_HOME>/webapps/axis2下
注意：浏览器需要安装jre1.3以上的插件来支持applet运行

2.配置servlet，在<CATALINA_HOME>/webapps/axis2/WEB-INF/web.xml中加上以下内容
    <servlet>
       <servlet-name>SOAPMonitorService</servlet-name>
       <display-name>SOAPMonitorService</display-name>
       <servlet-class>
         org.apache.axis2.soapmonitor.servlet.SOAPMonitorService
       </servlet-class>
       <init-param>
          <param-name>SOAPMonitorPort</param-name>
          <param-value>5001</param-value>
       </init-param>
       <load-on-startup>1</load-on-startup>
    </servlet>

    <servlet-mapping>
        <servlet-name>SOAPMonitorService</servlet-name>
        <url-pattern>/SOAPMonitor</url-pattern>
    </servlet-mapping>

3.装载soapmonitor模块
冷装载：<CATALINA_HOME>/webapps/axis2/WEB-INF/conf/axis2.xml中插入一行
<module ref="soapmonitor"/>，重启tomcat；
或者使用web方式热装载：http://localhost:8080/axis2/axis2-admin登陆后选Engage Module进行操作。热装载在在线运行系统的调试方面很有用。

4.观察监控信息
连接http://localhost:8080/axis2/SOAPMonitor，就可以用图形界面可视化的监控soap消息了，附图是一个实际监控情况。

还有我的QQ：307216786
可以和你交流下吗

我看了很多的关于SOAPMonitor部署步骤
可是我在访问http://localhost:8080/axis2/SOAPMonitor时就出现了以下的错误：java.lang.NullPointerException

环境变量、路径什么的，我都配了。
请问我这是什么回事？会是版本的问题吗？

1 楼 fenxue 2008-09-28  

问一下，我也准备采用2的版本，看了官方的文档，布署服务时可能要打包成一个aar文件，扔到WEB-INF/services目录下,感觉不像1版本那样，可以直接调试，现在只能通过监视器，或日志查看正误了，不知道楼主有没有好的解决方案？？？有空可以加我的QQ：87961327，一起交流。
