只有红色部分是我的代码.但看了对应的代码,根本没什么问题!
而且是运行一段时间Tomcat才会报这样的错误.
出现这个错误以后刷新页面有的时候好时.有的时候会出现白页.网上找了一下有人跟我遇到同样的问题,但都没有解决办法.LogoAlarmAction.java 22,23行:
response.setContentType("text/xml");
response.setHeader("Cache-Control", "no-cache");ActionBase.java:310,311行map = new CastMap((Map) indata.getMap());
strRlt = this.invoke(map, userinfo,request);--------------------------------------------------------------------------------

不知道如何查起.因为看错误报告,唯一2个是我的代码的地方,应该没有问题啊.更奇怪的是,我换了一台机器,跑了一晚上了也没出现这个问题.
会不会跟机器中的tomcat或者jdk安装配置有关?不太懂.请各位帮忙分析分析.
上面贴的代码就是可能的代码,再往下就是tomcat自带的jar了.
想不通问题出在哪.以为有人遇到过,所以发上来看看有没有解决办法.
