Glenn,
You're right: thanks for the correction. The scriplet should read
<%
String a = "foo";
String b = new String(a);
pageContext.setAttribute("a", a);
pageContext.setAttribute("b", b);
%>
The point remains: the JSTL expression language's '==' operator leads to
a call t
Shawn,
Just to clarify - your code snippet is very misleading. The reason
evaluates to true is because null == null, not
because "a == b" where a = "foo". a & b are not in any scope so in the
EL, a & b are null - in fact it doesn't matter what you set a or b to.
Changing your example a little

Are you sure the strings are really identical? For instance, just to be
sure you're using two different Strings with the same value, you can
experiment via the String copy constructor. Doing this demonstrates that
JSTL's '==' operator does work correctly:
<%@ taglib prefix="c" uri="http://jav
I'm try to compare two string fields in a MySql table row
here's my code that evaluate false even if the strings are identical:
SELECT * FROM FILIALI_EXT_LOG LEFT JOIN FILIALI_EXT USING (ID)
WHERE FILIALI_EXT_LOG.LASTMODI >
