Problem with JSTL functions

[Joshua Cloch]

Hey guys,

Here is the problem: suppose i want to check whether string A contains string B.

I may use this funtion: <c:if test="${fn:contains(A, B)}">

If A is a varibles,for example,A is defined as ${param.customerName};B is a constant:tom

The funtion is converted into:

c:if test="${fn:contains('${param.customerName}', 'tom')}">

Problem occurs! The tomcat server wont get the value defined by ${param.customerName},instead,it just treat it as a constant string.

Any ideas?

c:if test="${fn:contains('${param.customerName}', 'tom')}">

Your syntax is hosed.

The ${} notation is used to surround an entire EL expression. It's not some sort of "fetch" operator. They cannot be nested.

Remove the nested ${}.
