Cannot connect to Oracle 12c from Tomcat 6: no matching authentication protocol (ORA-28040)

I have to connecto to an Oracle 12c database from Tomcat 6. I made a servlet that create a connection to this datasource (from META-INF/context.xml):

<Context debug="0" docBase="/Test" path="/" reloadable="true">
   <Resource
      name="jdbc/test" auth="Container" type="javax.sql.DataSource"
      driverClassName="oracle.jdbc.OracleDriver"
      url="jdbc:oracle:thin:@somewhere:someport:someservice"
      username="someuser" password="somepass" maxActive="10" maxIdle="5"
      maxWait="5000" removeAbandoned="true" removeAbandonedTimeout="60"
      logAbandoned="true"
   />
</Context>

When I create the connection using this code:

InitialContext initContext = new InitialContext();
Context ctx = (Context) initContext.lookup("java:comp/env");
DataSource ds = (DataSource) ctx.lookup("jdbc/test");
conn = ds.getConnection();

I get the following exception:

    ... 18 more

But creating the connection with this code

Class.forName("oracle.jdbc.driver.OracleDriver");
conn = DriverManager.getConnection("jdbc:oracle:thin:@somewhere:someport:someservice", "someuser", "somepass");

works fine; moreover, if I use an URL to an Oracle 11g database in the servlet, it works.

I am using ojdbc6.jar driver for Oracle 12c, Tomcat 6, Java 1.6, Windows 7. Anyone have some hints?

Works for me, but with the parameter SQLNET.ALLOWED_LOGON_VERSION_SERVER

I set it to 8 to be sure.

See the doc : http://docs.oracle.com/database/121/NETRF/sqlnet.htm#NETRF2016

You probably have set the SQLNET.ALLOWED_LOGON_VERSION in the sql.net ora file on the server.
