Data Base Connection using Groovy Script in SOAP UI

I am trying to connect to Data base and getting the below error.

Executed the below query and getting some exception in error log.:

QUERY :

import groovy.sql.Sql
//import groovy.sql.*
import java.sql.SQLException
import oracle.jdbc.driver.*
//import com.eviware.soapui.support.GroovyUtils.*

// Set up database connection properties.
def url = '' /* IMPORTANT: must start with jdbc:mysql:// */
def user = ''
def password = ''
def driver = 'oracle.jdbc.driver.OracleDriver'

// Register the MySQL JDBC driver – required for Groovy to send requests to the database.
com.eviware.soapui.support.GroovyUtils.registerJdbcDriver(driver)

// Connect to the SQL instance.
def sql = Sql.newInstance(url, user, password,driver)

// Use the SQL instance.
sql.execute('')

// Close the SQL instance.
sql.close();

Exception :

Can anyone help me here ?

Setup :

I have added the JDBC files in to C:\Program Files\SmartBear\SoapUI-5.4.0\lib and C:\ProgramFiles\SmartBear\SoapUI-5.4.0\bin\ext. Still getting the same error. Did restart after the above setup also
