R to Mongo DB authentication failing

[AarthyBS]

Hi,
I was trying to connect to mongo db in three ways.
Its mongo version 3.0.4

1. using rmongodb - which fails with the error 'authentication failed'.
2. using RMongo - which also fails with the following error
   Error in .jcall(rmongo.object@javaMongo, "Z", "dbAuthenticate", username, :
   java.lang.NoSuchMethodError: com.mongodb.DB.authenticate(Ljava/lang/String;[C)Z
3. trying JDBC connection using jar files.
   drv <- JDBC("com.mongodb.MongoClient",list.files("path:/",

• pattern="jar$",full.names=T))
  con<-dbConnect(drv,"jdbc:mongodb://host:port/dbname",user,pwd)
  again this throws the following error:
  Error in .jcall(drv@jdrv, "Ljava/sql/Connection;", "connect", as.character(url)[1], :
  method connect with signature (Ljava/lang/String;Ljava/util/Properties;)Ljava/sql/Connection; not found

Can somebody help with the next step to follow.
