错误3:tomcat启动时出现 :Address already in use: JVM_Bind 解决3:端口已经被占用,额外设置 tomcat的启动端口
错误4:启动BI后,访问页面报错 HTTP STRUTS 500 description: the server encountered an internal error that prevented it from fulfilling the request exception: java.lang.NullPointerException 解决4:license 过期了,重新申请license。(根据具体场景做判断,有时候不一定是license问题,license解析是有效的则需要检查其他原因)
