Play Framework (2.4) and DB2 configuration - scala

Question

I am developing a web application in Scala with Play 2.4 which needs to connect to DB2, Vertica, MySQL, and others.
Vertica and MySql configuration is working fine but I am not able to connect to DB2, version 10.5, fix pack 5.
Here is the application.conf setting
db.db2.driver=com.ibm.db2.jcc.DB2Driver
db.db2.url="jdbc:db2://host:port/database"
db.db2.username="user"
db.db2.password="pass"
db.db2.logStatements=false
db.db2.initSQL="select 1 from sysibm.sysdummy1"
I am using the following type 4 JDBC Drivers:
db2jcc.jar
db2jcc4.jar
However, I am getting the following errors (apologize for a long error message):
Unexpected exception
CreationException: Unable to create injector, see the following errors:

I guess you're missing this:
Caused by: java.sql.SQLException: JDBC4 Connection.isValid() method not supported, connection test query must be configured
Since you are supplying both JDBC 3.0 (db2jcc.jar) and JDBC 4.0 (db2jcc4.jar) drivers, you cannot guarantee which of the two drivers will be loaded.
To ensure JDBC 4 functionality leave only db2jcc4.jar in the classpath.
