You may already have guessed that ClassNotFoundException meens that a class can not be found (by the classloader). In this case is the class com.linkdom.intercom.listener.ContextListener not available to the classloader.

You may check that you have the library, that includes this file, on the classpath, ie in your war-file that is deployed in Tomcat or in the /lib folder in Tomcat (there can be other options where the library may be added to the classpath depending on your setup).

actually this a custome file included in my dir – Maltesh B K Aug 22 '23 at 14:39
Make sure your custom java file is compiled and that the resulting class-file (not the java-file) is included on the classpath – joran Aug 24 '23 at 19:38
