websphere在控制台重启应用程序后报错，请各位帮忙看一下
注：websphere服务器重启后，就不会报错了，但当在websphere的控制台中对应用程序重启后就会出现！应用程序是spring+hibernate+spring-mvc
1、dwr的服务器页面推送，页面不显示信息，我log打印了一下通过以下方法中的allSessionss为null。
DefaultServerContext sctx = (DefaultServerContext) ServerContextFactory.get();
Collection<ScriptSession> allSessionss = sctx.getAllScriptSessions();
2、通过以下方法取spring容器中加载的信息wac为null。
WebApplicationContext wac = ContextLoader.getCurrentWebApplicationContext();
以上两段程序都是在服务器端口监听进程中调用的。同时还报以下错误
