- Liferay: No suitable driver found 1 answer
Back in the old days, you had to load the appropriate driver class using Class.forName(org.postgresql.Driver.class) construct. With JDBC 4.0 drivers it's no longer necessary - but you may give it a try.
Alternatively, try starting your application with -Djdbc.drivers=org.postgresql.Driver, it does virtually the same as Class.forName snippet, but doesn't require you to hardcode the driver class. Hope it helps.
