I have a class called "DmsCheckinDoc". This class will invoke another class based on the "appName" parameter passed to it. If parameter passed is "cobs" then class "CobsHandler" will be invoked. If parameter passed in "dobs" then "DobsHandler" will be invoked.

The "DmsCheckinDoc" looks something like this



The decision as to which handler class to invoke is there in "DmsCheckinFactory". The lookup method finds out the handler class (from a properties file) based on the appName parameter. The "DmsCheckinFactory" looks like this



One of the handler class looks something like this


The interface implemented by CobsHandler looks like this


Can someone please let me know if the above approach is correct. Given these requirements, am I implementing the design pattern correctly?

Thank you
