Cannot use teleporter for DB2

We are using DB2 as our primary database. We want to use teleporter for data syncronisation, data viewing etc.

I had checked jdbc-drivers.json in config directory in orientdb. There is no such configuration for DB2.

In jdbc-drivers.jso for all the other databases there is direct url reference to driver jar files from some sites.
But for DB2 there is no such direct links.

So, I added the following script to the bottom of jdbc-drivers.json and added the db2 driver in lib folder in orientdb.

"DB2": {
    "className": "com.ibm.db2.jcc.DB2Driver",
    "url":"/home/yashaswini/orientDB/orientdb-enterprise-2.2.3/lib/db2jcc.jar",
    "version":"4.1.0",
    "format":[
         "jdbc:db2://<HOST>:<PORT>/<DB>"
    ]

    }

Though I have mentioned DB2 as additional database in jdbc-drivers.json, it doesn't show up in drop down of database list in teleporter page in OrientDB studio.

Is there any way I can get DB2 working in teleporter?
I would be grateful if anyone can help me in this regard.

Below is the whole script of jdbc-drivers.json after I edited.
