           myCollection = testDB("mycol")//get collection Name

please explain what is the difference

Solution

MongoConnection has been deprecated in favor of MongoClient. To my knowledge there was no difference at the time MongoClient was introduced. I guess the functionality may diverge over time.

From the API tutorial: Casbah API tutorial

"MongoClient was added to the Java driver in 2.10 as the default connection class for MongoDB. Older Casbah code may use MongoConnection which should be updated to use MongoClient."
