After Couple of days of searching and integrating i found the solution .....

  1. Why a ClassNotFoundException exception occurs most frequently here the article is real good ...

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

  2. The main reason of the problem shows the log java.lang.ClassNotFoundException: javax.servlet.AsyncContext

    it means it is not finding the asyncContext class provided by javax.servlet-3.0 . In servlet 2.5 its missing.

i was running Apache Tomcat 7 in localhost, but in local server 192.168.1.10 i was running Apache Tomcat 6 . In the given link apache doc says the servlet version.

 So the solution is either anyone upgrade the Apache Tomcat 6 to Apache Tomcat 7
 or posting the file javax.servlet-3.0 in Apache Tomcat 6 lib folder.
 [Here][3] is the jar file.

You can also force your Grails app to use Servlet 2.5 In your BuildConfig.groovy

grails.servlet.version = "2.5"

Hope it helps
