ORA-28040: No matching authentication protocol exception when using groovy.sql package with oracle12c

Question

I am trying to connect to oracle12c database using groovy.sql.Sql

Sql sql = Sql.newInstance('jdbc:oracle:thin:@'+hostName:port/serviceName, dbUser, dbPassword, 'oracle.jdbc.driver.OracleDriver')

and it returns

java.sql.SQLException: ORA-28040: No matching authentication protocol

I guess, this is because of the dialect mismatch.

It works fine with oracle11g, but not with 12c. If it is a problem with dialect, how can we externally specify dialect to groovy.sql.Sql. If not, what could be the problem/solution?

I'm using ojdbc14 driver.

Solution

The ojdbc14 is a relatively old driver and that could be the problem. I would recommend trying ojdbc6 and see if that fixes your problem.

Note that this appeared to fix a similar problem based on information in the comments in this SO question ORA-28040: No matching authentication protocol exception.

No, actually I am trying to dynamically connect to some other databases from my application.

Yes, ojdbc6 has fixed the problem
