V.Thangavelu, I ran into a similar error as what you state below a month or so ago.
Chuck Caldarale had made the suggestion, and it turned out to be the elixir for me, was to make ABSOLUTELY sure you had NO other classes (or jar files) of the same name, i.e. tomcat-dbcp.jar, floating around elsewhere in the directory anywhere. It not only can, but will wreak havoc on this DBCP connection. Double check that, clean it out if you find extras, kill of the context.xml file created from META-INF/ in the conf directory. And try again. That worked wonders for me.
