Tomcat : error on token "enum" ?

[Lalit Nagalkar]

I tried "ShowHeaders.jsp" in "java servlet and jsp- by falker and jones"
I am getting following error :-
(code works after changing "enum" to any other valid variable name)

Can any one please tell me what's goin on?

THANKS in advance....

Moved to the Tomcat forum.

What JDK are you using? It could because enum is a keyword.

[Lalit Nagalkar]

i am using jdk 1.5/tomcat 5.5

If enum is keyword how come the authors made mistake

[Masoud Kalali]

it means that main author used enum as a variable name and in java 5 enum is a keyword, so it return a compiler error as it is in violation ith language rules (the book is not for tomcat 5.5 and java 5)

you can use tomcat 5.5.x with an older jdk to compile the code with no error.
but you will need tomcat compatibility pack to use tomcat 5.5 with jdk 1.4.x
