public class Constants {

    public final static String SIMPLE_CAPCHA_SESSION_KEY =

    public final static String SIMPLE_CAPTCHA_BOX = "cap.border";
    public final static String SIMPLE_CAPTCHA_BOX_C = "cap.border.c";
}

actually this might be simple problem but i cannot understand the
problem.. can u [sic] please help me....

"u" is txtspeek, not English.

I suspect that your 'Constants' class is not in scope for the servlet. What
is the ".class" file organization of the WAR?

I'm also suspicious of the way you deployed it. What happens if you use the
Tomcat deployer app? I've never seen an app deployed to a subdirectory of a
subdirectory of "webapps/" so it looks fishy.

Can you prepare an SSCCE?
