org.apache.el.parser.ParseException 由tomcat版本导致

在搭建一个web工程项目过程中，发现某个jsp页面报错，前台显示报错是“Stream closed"，查看后台日志，报错为如下代码。

搞不清楚状况，以为是代码错误，后来经过定位发现，原因是tomcat 有的版本不支持此el表达式，搭建环境使用的是myeclipse10自带tomcat，版本为6.0.13，不支持就更换tomcat版本。

果然，更换tomcat版本为7之后，问题没有再出现了，记录下问题，供有类似情况的同学查看。

严重: Servlet.service() for servlet jsp threw exception
org.apache.el.parser.ParseException: Encountered "templateInfo.backgroupColor: \'#FFFFFF\'" at line 1, column 37.
Was expecting one of:

    <IDENTIFIER> ...
