发帖数: 361 | 1 It seems that EL is trying hard to convert my strings to double values. I
am confused. I remember the plus operator (+) can be used to concatenate
strings. Did I do anything wrong? What's the better way to deal with this?
I am using Tomcat 5.5.17 and JDK 1.5.0_06 on WinXP Home.
Thanks.
1: Working code
<%
String resourceType = "service";
pageContext.setAttribute("resourceType", resourceType);
pageContext.setAttribute("resourceName", resourceType + "Name");
%>

concatenate two strings within the ${} scope, not that I know of. I know, it

发帖数: 361 | 4 Thanks. This is a solution.
However, not being able to concatenate strings within EL makes simple things
more difficult and less straightforward. I agree with magicfat that this
is stupid. Anyway, I am not that smart either and I can live with it :)
