Reverse Engineering does not work

Hi,

I am trying to reverse engineer an existing database in MS SQL Server. I need to extend database capabilities and therefore need the existing model to start with. 

I am using the following connection string but getting an error. 

Can you please advise if this command is right? 

java -jar reverse-engineering.jar com.vertabelo.reverse.Main -url jdbc:sqlserver://00.11.222.333\MMISQLE16,1433 -user xxx -password xxxxxx -o qa_db

The error message is as follows: 

No JDBC driver given. Using JDBC driver: com.microsoft.sqlserver.jdbc.SQLServerD
