Oracle Database connection in play framework 2.5.10 - playframework-2.5

Question

I am unable to connect the oracle database in play framework.
Steps I followed as below:
configuration of database in application.conf file as below:
default.driver=oracle.jdbc.driver.OracleDriver
default.url="jdbc:oracle:thin:#localhost:1521:XE"
default.username=username
default.password=password
->added ojdbc14.jar in lib folder in the project
while hitting the browser with url http://localhost:9000
I am getting below error:
Cannot connect to database [default]
exception is as below on console:
[error] c.z.h.p.PoolBase - HikariPool-1 - Failed to execute isValid() for connection, configure connection test query. (oracle.jdbc.driver.T4CConnection.isValid(I)Z)
[info] application - Creating Pool for datasource 'default'

any advice will be appreciated.

Answer 1

Essentially, the problem is Oracle connectivity with ojdbc14.jar is not supported by Play Framework.
I tried with ojdbc6 for Oracle 11g and it worked.
