How to know if a class or resource bundle is deployed into ATG Dynamo server

Into your atg server go to the following Path /dyn/dyn/findclass.jhtml i.e. http://localhost:8180/dyn/dyn/findclass.jhtml and type the full qualified name of the class or resource bundle, and it will let you know where is that .class deployed

This is very useful to when you are facing an issue where a class your are debugging is not being reached, simply search for that and if is deployed you will know where is.
