Welcome to the JavaRanch, Chowdary!

I'm uncomfortable with your Windows pathnames ("C:\development\ ..."). Backslashes can often bite. I prefer the safer form: "C:/development/...".

As I read it, the Ant script is deploying a WAR into a running Tomcat when it fails. You didn't provide much context for the exception, however. If the webapp itself is attempting the use class org.apache.tomcat.util.codec.binary.Base64, then it's probably right to fail. Webapps should not attempt to directly employ Tomcat's internal classes.

If Tomcat is failing, then the stacktrace and related information from the Tomcat catalina.out console log would be useful.
