Summary: Expression Language fails parsing a correct
expression.
Product: Tomcat 6
Version: 6.0.18
Platform: PC
OS/Version: Windows XP
Status: NEW
Severity: major
Priority: P2
Component: Jasper
AssignedTo: [email protected]
ReportedBy: [email protected]
Hi,
If you create a JSP and paste the following expression Tomcat fails executing
it.
Test ${not(true)}
if you put a space between the "not" and "(" it works:
Test ${not (true)}
This worked in Tomcat 6.0.16 but not in Tomcat 6.0.18.
This the exception that you get when it fails.
