after couple of days of searching , integrating found solution .....

  1. why classnotfoundexception exception occurs here article real ...

    http://javarevisited.blogspot.com/2011/08/classnotfoundexception-in-java-example.html

  2. the main reason of problem shows log java.lang.classnotfoundexception: javax.servlet.asynccontext

    it means not finding asynccontext class provided javax.servlet-3.0 . in servlet 2.5 missing.

i running apache tomcat 7 in localhost, in local server 192.168.1.10 running apache tomcat 6 . in given link apache doc says servlet version.

 solution either upgrade apache tomcat 6 apache tomcat 7  or posting file javax.servlet-3.0 in apache tomcat 6 lib folder.  [here][3] jar file.
