websphere发布应用，jsp的el表达式 ${fn.replace}报错：
[10/24/17 19:02:45:181 CST] 00000038 servlet E com.ibm.ws.webcontainer.servlet.ServletWrapper service SRVE0068E: An exception was thrown by one of the service methods of the servlet [/WEB-INF/jsp/modules/xx/xx.jsp] in application [xx_war]. Exception created : [javax.el.ELException: Function ‘fn:replace‘ not found
at org.apache.el.lang.ExpressionBuilder.visit(ExpressionBuilder.java:197)
at
错误原因：websphere不能正确处理单引号包裹的el表达式的函数。
解决方法：在el表达式外面用双引号包裹，而不是单引号。
例子如下：
有问题的jsp代码
<div id =‘${fn:replace(pdata.attributes.type, "|", "_")}_invest${ind.index}‘ ></div>
修改为：
<div id ="${fn:replace(pdata.attributes.type, ‘|‘, ‘_‘)}_invest${ind.index}" ></div>
