查找错的几种方式·

今天头儿给现场演示了怎么找看不到的页面

 

1.   在显示不出的页面上单击右键，查看出错的信息

    例如;

<input type="hidden" name="ExceptionName" value="java.lang.NullPointerException

at java.util.Hashtable.put(Hashtable.java:396)

at _jsp._nos._netflow._netflow._CurMonitorDetail__jsp._jspService(_CurMonitorDetail__jsp.java:643)

at com.caucho.jsp.JavaPage.service(JavaPage.java:61)

at com.caucho.jsp.Page.pageservice(Page.java:578)

at com.caucho.server.dispatch.PageFilterChain.doFilter(PageFilterChain.java:195)

at com.zhongying.util.EncodingFilter.doFilter(EncodingFilter.java:80)

at com.caucho.server.dispatch.FilterFilterChain.doFilter(FilterFilterChain.java:87)

at com.caucho.server.webapp.WebAppFilterChain.doFilter(WebAppFilterChain.java:187)

at com.caucho.server.dispatch.ServletInvocation.service(ServletInvocation.java:266)

at com.cauho.server.hmux.HmuxRequest.handleRequest(HmuxRequest.java:435)

at com.caucho.server.port.TcpConnection.run(TcpConnection.java:678)

at com.caucho.util.ThreadPool$Item.runTasks(ThreadPool.java:721)

at com.caucho.util.ThreadPool$Item.run(ThreadPool.java:643)

at java.lang.Thread.run(Thread.java:595)

">

首先hashtable不会出错，所以锁定

        _jsp._nos._netflow._netflow._CurMonitorDetail__jsp._jspService(_CurMonitorDetail__jsp.java:643)，

 

用ftp工具打开slview/apache/htdocs/WEB-INF/work/_jsp/_nos/_netflow/_netflow/._jspService下的(_CurMonitorDetail__jsp.java

 

2。 页面上 有公司自定义的异常“查询流量监控字段信息出错”，secureCRT打开    more ErrorList.xml

 

<ErrorNode>
                <ErrorCode>com.zhongying.dslamprofile.busi.DslamProfileBusi:06</ErrorCode>
                <ErrorName>业务选择失败</ErrorName>
                <ErrorExplain>业务选择失败</ErrorExplain>
         </ErrorNode
